CMD workers are working fine because they're directed to F:\software\Flamenco 3.7, and i9kf is working fine because I've installed flamenco 3.7 to that local path. Can we have Launch Standard Worker run the worker executable in F:\software\Flamenco 3.7 ?

Yes, you can have the "Launch Standard Worker" option run the worker executable from `F:\software\Flamenco 3.7` for all systems, just like the CMD workers. Currently, the `Get-RemoteStandardWorkerCommand` function is set up to run the worker from `C:\Program Files\Blender Foundation\Flamenco 3.7` if it exists, but you want it to always use `F:\software\Flamenco 3.7\flamenco-worker.exe`.
|
|||
|
|
|
|||
|
|
**Here's what you need to do:**
|
|||
|
|
|
|||
|
|
- Update the `Get-RemoteStandardWorkerCommand` function so that it always sets the location to `F:\software\Flamenco 3.7` and runs `flamenco-worker.exe` from there, regardless of whether the directory exists in `C:\Program Files\...`.
|
|||
|
|
|
|||
|
|
---
|
|||
|
|
|
|||
|
|
**How to update:**
|
|||
|
|
|
|||
|
|
Replace the entire worker start block in `Get-RemoteStandardWorkerCommand` with the following:
|
|||
|
|
|
|||
|
|
```powershell
|
|||
|
|
# Start worker
|
|||
|
|
Write-Host "Starting Flamenco worker..." -ForegroundColor Cyan
|
|||
|
|
Set-Location 'F:\software\Flamenco 3.7'
|
|||
|
|
if (Test-Path 'flamenco-worker.exe') {
|
|||
|
|
Write-Host "Running flamenco-worker.exe..." -ForegroundColor Green
|
|||
|
|
# Run the worker and capture its exit code
|
|||
|
|
$workerProcess = Start-Process -FilePath '.\flamenco-worker.exe' -NoNewWindow -PassThru -Wait
|
|||
|
|
$exitCode = $workerProcess.ExitCode
|
|||
|
|
Write-Host "Flamenco worker process has terminated with exit code: $exitCode" -ForegroundColor Yellow
|
|||
|
|
exit $exitCode # Exit with the worker's exit code to trigger restart if needed
|
|||
|
|
} else {
|
|||
|
|
Write-Host "Error: flamenco-worker.exe not found in F:\software\Flamenco 3.7" -ForegroundColor Red
|
|||
|
|
exit 1 # Exit with error code to trigger restart
|
|||
|
|
}
|
|||
|
|
```
|
|||
|
|
|
|||
|
|
**Remove** the check for `C:\Program Files\Blender Foundation\Flamenco 3.7` entirely.
|
|||
|
|
|
|||
|
|
---
|
|||
|
|
|
|||
|
|
**Result:**
|
|||
|
|
- All "Standard Worker" launches will use the 3.7 executable from `F:\software\Flamenco 3.7`, just like your CMD workers.
|
|||
|
|
- This will ensure consistency across all your worker launches.
|
|||

WRN unable to send sign-on request error="Post \"http://localhost:8888/api/v3/worker/sign-on\": dial tcp [::1]:8888: connectex: No connection could be made because the target machine actively refused it." manager=http://localhost:8888/
|
|||
|
|
```
|
|||
|
|
|
|||
|
|
means that the Flamenco worker is trying to connect to a Flamenco Manager at `http://localhost:8888/`, but nothing is listening on that port on the remote machine. This is a **network/configuration issue**, not a script or launcher bug.
|
|||
|
|
|
|||
|
|
### Why does this happen?
|
|||
|
|
|
|||
|
|
- **Each worker runs on its own machine.**
|
|||
|
|
- By default, the worker tries to connect to a manager at `localhost:8888` (i.e., itself).
|
|||
|
|
- Unless the Flamenco Manager is running on that same machine and on that port, the connection will fail.
|
|||
|
|
|
|||
|
|
### Why does i9kf work?
|
|||
|
|
|
|||
|
|
- On i9kf, you probably have the Flamenco Manager running locally, or the worker's config points to the correct manager address.
|
|||
|
|
|
|||
|
|
### Why do the others fail?
|
|||
|
|
|
|||
|
|
- On the other machines, the worker is trying to connect to `localhost:8888`, but the manager is not running there (or not on that port).
|
|||
|
|
|
|||
|
|
---
|
|||
|
|
|
|||
|
|
## How to Fix
|
|||
|
|
|
|||
|
|
You need to make sure that **each worker's configuration file** (`flamenco-worker.yaml`) points to the correct Flamenco Manager address (the actual host/IP where the manager is running, not `localhost`).
|
|||
|
|
|
|||
|
|
### Steps:
|
|||
|
|
|
|||
|
|
1. **Find the manager's real address.**
|
|||
|
|
- If the manager is running on i9kf, use its network name or IP, e.g., `http://i9kf:8888/` or `http://192.168.1.100:8888/`.
|
|||
|
|
|
|||
|
|
2. **Update the worker config on each machine:**
|
|||
|
|
- Open `flamenco-worker.yaml` (location is shown in the worker's startup log, e.g., `C:\Users\Nathan\AppData\Local\Blender Foundation\Flamenco\worker-2\flamenco-worker.yaml`).
|
|||
|
|
- Find the line like:
|
|||
|
|
```yaml
|
|||
|
|
manager: http://localhost:8888/
|
|||
|
|
```
|
|||
|
|
- Change it to:
|
|||
|
|
```yaml
|
|||
|
|
manager: http://i9kf:8888/
|
|||
|
|
```
|
|||
|
|
or whatever the correct address is for your network.
|
|||
|
|
|
|||
|
|
3. **Restart the worker** after saving the config.
|
|||
|
|
|
|||
|
|
---
|
|||
|
|
|
|||
|
|
## Why does this only affect "Standard Worker"?
|
|||
|
|
|
|||
|
|
It doesn't—**all workers will have this problem** if their config points to the wrong manager address. The difference is likely that i9kf is the manager host, so `localhost` works there, but not on the other machines.
|
|||
|
|
|
|||
|
|
---
|
|||
|
|
|
|||
|
|
## TL;DR
|
|||
|
|
|
|||
|
|
- The error is because the worker is trying to connect to a manager on `localhost`, but there is no manager running there.
|
|||
|
|
- Update the `manager:` line in each worker's `flamenco-worker.yaml` to point to the correct network address of your Flamenco Manager.
|
|||
|
|
- Restart the workers.
|
|||
|
|
|
|||

why does flamenco-manager.exe close immediately every time I start it?
|
|||
|
|
|
|||
|
|
---
|
|||
|
|
|
|||
|
|
_**Assistant**_
|
|||
|
|
|
|||
|
|
When `flamenco-manager.exe` closes immediately after you start it, it usually means **one of the following**:
|
|||
|
|
|
|||
|
|
---
|
|||
|
|
|
|||
|
|
### 1. **Missing or Invalid Configuration**
|
|||
|
|
- Flamenco Manager requires a valid configuration file (`flamenco-manager.yaml`).
|
|||
|
|
- If the config file is missing, malformed, or has invalid values, the manager will exit immediately (sometimes with an error message, sometimes silently if run from Explorer).
|
|||
|
|
|
|||
|
|
**How to check:**
|
|||
|
|
- Open a terminal (PowerShell or CMD).
|
|||
|
|
- Run `flamenco-manager.exe` from the command line, **not** by double-clicking.
|
|||
|
|
- Observe any error messages printed to the terminal.
|
|||
|
|
|
|||
|
|
---
|
|||
|
|
|
|||
|
|
### 2. **Port Already in Use**
|
|||
|
|
- If another process is already using the port (default: 8888), the manager will fail to start and exit.
|
|||
|
|
|
|||
|
|
**How to check:**
|
|||
|
|
- Run from terminal and look for errors about "address already in use" or similar.
|
|||
|
|
|
|||
|
|
---
|
|||
|
|
|
|||
|
|
### 3. **Missing Dependencies**
|
|||
|
|
- Flamenco Manager may require certain files or dependencies in the same directory (e.g., config, database).
|
|||
|
|
- If you moved only the `.exe` and not the supporting files, it may fail.
|
|||
|
|
|
|||
|
|
---
|
|||
|
|
|
|||
|
|
### 4. **Permissions**
|
|||
|
|
- If the user running the manager does not have permission to bind to the port or access required files, it may exit.
|
|||
|
|
|
|||
|
|
---
|
|||
|
|
|
|||
|
|
### 5. **Crash or Unhandled Exception**
|
|||
|
|
- If there is a bug or incompatibility, the manager may crash. Running from terminal will show a stack trace or error.
|
|||
|
|
|
|||

|
|||
|
|
|
|||
|
|
## **What to Do**
|
|||
|
|
|
|||
|
|
1. **Always run from a terminal** (PowerShell or CMD), not by double-clicking.
|
|||
|
|
This way, you can see any error output.
|
|||
|
|
|
|||
|
|
2. **Check for error messages** in the terminal.
|
|||
|
|
|
|||
|
|
3. **Verify configuration:**
|
|||
|
|
- Make sure `flamenco-manager.yaml` exists in the expected location.
|
|||
|
|
- Check for typos or invalid values.
|
|||
|
|
|
|||
|
|
4. **Check for port conflicts:**
|
|||
|
|
- Make sure nothing else is using port 8888 (or whatever port you set).
|
|||
|
|
|
|||
|
|
5. **Check logs:**
|
|||
|
|
- Flamenco Manager may write logs to a file or the console. Look for any log files in the same directory.
|
|||
|
|
|
|||
|

|
|||
|
|
|
|||
|
|
## **Common Fix Example**
|
|||
|
|
|
|||
|
|
If you see an error like:
|
|||
|
|
```
|
|||
|
|
Error: failed to read configuration: open flamenco-manager.yaml: The system cannot find the file specified.
|
|||
|
|
```
|
|||
|
|
→ You need to create or copy the config file to the same directory as the `.exe`.
|
|||
|
|
|
|||
|
|
If you see:
|
|||
|
|
```
|
|||
|
|
Error: listen tcp 0.0.0.0:8888: bind: An attempt was made to access a socket in a way forbidden by its access permissions.
|
|||
|
|
```
|
|||
|
|
→ The port is in use or you lack permissions.

how to change to PATH blender?

|
|||
|
|
|
|||
|
|
_**Assistant**_
|
|||
|
|
|
|||
|
|
To make Flamenco Manager use the `blender` found in your system `PATH` (instead of a hardcoded path), you should set the value to just `blender` (no path, no `.exe`), like this:
|
|||
|
|
|
|||
|
|
```yaml
|
|||
|
|
variables:
|
|||
|
|
blender:
|
|||
|
|
values:
|
|||
|
|
- platform: linux
|
|||
|
|
value: blender
|
|||
|
|
- platform: windows
|
|||
|
|
value: blender
|
|||
|
|
- platform: darwin
|
|||
|
|
value: blender
|
|||
|
|
```
|
|||
|
|
|
|||
|
|
This tells Flamenco to run `blender` as a command, which will use whatever Blender is found first in the system `PATH` on each platform.
|
|||
|
|
|
|||
|
|
---
|
|||
|
|
|
|||
|
|
**How to do it:**
|
|||
|
|
1. Open your `flamenco-manager.yaml` file.
|
|||
|
|
2. Find the `variables: blender:` section.
|
|||
|
|
3. Change each `value:` to just `blender` as shown above.
|
|||
|
|
4. Save the file.
|
|||
|
|
5. Restart Flamenco Manager.
|
|||
|
|
|
|||
|
|
---
|
|||
|
|
|
|||
|
|
**Note:**
|
|||
|
|
- Make sure `blender` is available in the `PATH` on each machine where workers run.
|
|||
|
|
- You can check this by opening a terminal and running `blender`—it should launch Blender.
|
|||

|
When you launch `flamenco-manager.exe` and it goes through the setup procedure, it usually means **one of these is true**:
|
|||
|
|
|
|||
|
|
1. **It cannot find your existing configuration file (`flamenco-manager.yaml`).**
|
|||
|
|
2. **It cannot find your existing database file (`flamenco-manager.sqlite`).**
|
|||
|
|
3. **You are running it from a different directory than before, so it creates new files.**

|

|
## How Flamenco Manager Locates Its Files
|
|||
|
|
|
|||
|
|
- By default, Flamenco Manager looks for `flamenco-manager.yaml` and `flamenco-manager.sqlite` in the **current working directory** (the directory you launch it from).
|
|||
|
|
- If it doesn't find them, it starts the setup wizard and creates new files.
|
|||
|
|
|
|||
|
|
---
|
|||
|
|
|
|||
|
|
## How to Fix
|
|||
|
|
|
|||
|
|
**Always launch `flamenco-manager.exe` from the directory where your config and database are located.**
|
|||
|
|
|
|||
|
|
### Example
|
|||
|
|
|
|||
|
|
If your files are in:
|
|||
|
|
```
|
|||
|
|
C:\Program Files\Blender Foundation\Flamenco 3.7\
|
|||
|
|
```
|
|||
|
|
then you should:
|
|||
|
|
|
|||
|
|
1. Open a terminal (PowerShell or CMD).
|
|||
|
|
2. Run:
|
|||
|
|
```powershell
|
|||
|
|
cd "C:\Program Files\Blender Foundation\Flamenco 3.7"
|
|||
|
|
.\flamenco-manager.exe
|
|||
|
|
```
|
|||
|
|
|
|||
|
|
This way, it will find your existing `flamenco-manager.yaml` and `flamenco-manager.sqlite` and **not** start the setup wizard.
|
|||
|
|
|
|||
|
|
---
|
|||
|
|
|
|||
|
|
## Alternative: Specify Config and Database Paths
|
|||
|
|
|
|||
|
|
If you want to run the manager from anywhere, you can specify the config and database file locations explicitly:
|
|||
|
|
|
|||
|
|
```powershell
|
|||
|
|
.\flamenco-manager.exe --config "C:\Program Files\Blender Foundation\Flamenco 3.7\flamenco-manager.yaml" --database "C:\Program Files\Blender Foundation\Flamenco 3.7\flamenco-manager.sqlite"
|
|||
|
|
```

|||

If `flamenco-manager.exe` only works when you run it as administrator, this is almost always due to **file/folder permissions** or **port binding restrictions**. Here’s how to diagnose and fix it:

## 1. **File/Folder Permissions**
|
|||
|
|
|
|||
|
|
- If your config/database/log files are in a protected directory (like `C:\Program Files\...`), normal users may not have write access.
|
|||
|
|
- Running as admin works because admin can write anywhere.
|
|||
|
|
|
|||
|
|
**Solution:**
|
|||
|
|
Move your Flamenco Manager files (including `flamenco-manager.exe`, `flamenco-manager.yaml`, and `flamenco-manager.sqlite`) to a user-writable directory, such as:
|
|||
|
|
|
|||
|
|
```
|
|||
|
|
C:\Users\Nathan\Flamenco\
|
|||
|
|
```
|
|||
|
|
or
|
|||
|
|
```
|
|||
|
|
F:\software\Flamenco 3.7\
|
|||
|
|
```
|
|||
|
|
|
|||
|
|
Then run the manager from there.
|
|||
|
|
|
|||
|
|
**Or:**
|
|||
|
|
Change the permissions on the folder so your user account has full read/write access.
|
|||
|
|
|
|||

|
## 2. **Port Binding Restrictions**
|
|||
|
|
|
|||
|
|
- By default, Flamenco Manager uses port 8888, which is not a privileged port, so this is less likely the issue.
|
|||
|
|
- If you changed the port to something below 1024, only admin can bind to those ports.
|
|||
|
|
|
|||
|
|
**Solution:**
|
|||
|
|
Use a port above 1024 (default 8888 is fine).
|
|||
|
|
|
|||

|
|||
|
|
|
|||
|
|
## 3. **Other Causes**
|
|||
|
|
|
|||
|
|
- If you installed Flamenco Manager as a service, it may require admin to start/stop.
|
|||
|
|
- Antivirus or security software may block access for non-admin users.
|
|||
|
|
|
|||

|||
|
|
|
|||
|
|
## **How to Fix (Step-by-Step)**
|
|||
|
|
|
|||
|
|
1. **Move all Flamenco Manager files** to a folder you own (e.g., `C:\Users\Nathan\Flamenco`).
|
|||
|
|
2. **Open a terminal as your normal user** (not admin).
|
|||
|
|
3. **Navigate to that folder**:
|
|||
|
|
```powershell
|
|||
|
|
cd C:\Users\Nathan\Flamenco
|
|||
|
|
```
|
|||
|
|
4. **Run the manager**:
|
|||
|
|
```powershell
|
|||
|
|
.\flamenco-manager.exe
|
|||
|
|
```
|
|||
|
|
5. If it still fails, check for error messages about permissions or file access.

|
|
**Best Practice:**
|
|||
|
|
Keep all Flamenco files in a user-writable directory, and run as a normal user.
|
|||
|
|
Only use `C:\Program Files\...` for read-only binaries, not for configs or databases.

_**Assistant**_
|
|||
|
|
|
|||
|
|
This error means that when the worker tries to run `blender`, **the executable is not found in the environment’s `%PATH%`**. Even if you just added Blender to your user or system PATH, there are a few common reasons why it still fails:
|
|||
|
|
|
|||
|
|
---
|
|||
|
|
|
|||
|
|
## 1. **PATH Not Updated for the Worker Process**
|
|||
|
|
|
|||
|
|
- If you added Blender to your PATH after starting the worker, you must **restart the worker process** (and sometimes the whole machine, especially if running as a service or via SSH).
|
|||
|
|
- If the worker is running as a service or via a scheduled task, it may not inherit your user’s PATH.
|
|||
|
|
|
|||
|
|
---
|
|||
|
|
|
|||
|
|
## 2. **Blender Not in PATH for All Users/Sessions**
|
|||
|
|
|
|||
|
|
- If you added Blender to your PATH only for your user, but the worker runs as another user (e.g., SYSTEM, Administrator, or via SSH), it won’t see your user’s PATH.
|
|||
|
|
- **Check:** Open a new terminal (not one that was open before you changed PATH) and run `blender`. If it works, the PATH is set for that user/session.
|
|||
|
|
|
|||
|
|
---
|
|||
|
|
|
|||
|
|
## 3. **Blender Not in PATH on Remote Machines**
|
|||
|
|
|
|||
|
|
- Each worker runs on its own machine. You must add Blender to the PATH on **every machine** where a worker runs.
|
|||
|
|
|
|||
|
|
---
|
|||
|
|
|
|||
|
|
## 4. **Blender Not Actually in the PATH Directory**
|
|||
|
|
|
|||
|
|
- Double-check that the directory you added to PATH actually contains `blender.exe`.
|
|||
|
|
- Try running `where blender` in a terminal to confirm.
|
|||
|
|
|
|||
|
|
---
|
|||
|
|
|
|||
|
|
## 5. **Session/Environment Issues**
|
|||
|
|
|
|||
|
|
- If you launch the worker from a script or via SSH, make sure the PATH is set in that environment.
|
|||
|
|
- Sometimes, Windows needs a full log out/log in or reboot for PATH changes to propagate everywhere.
|
|||
|

|
|||
|
|
|
|||
|
|
## **How to Diagnose**
|
|||
|
|
|
|||
|
|
1. **On each worker machine, open a NEW terminal.**
|
|||
|
|
2. Run:
|
|||
|
|
```
|
|||
|
|
blender --version
|
|||
|
|
```
|
|||
|
|
- If it says "not found", PATH is not set up for that user/session.
|
|||
|
|
- If it prints the Blender version, PATH is correct.
|
|||
|
|
|
|||
|
|
3. Run:
|
|||
|
|
```
|
|||
|
|
where blender
|
|||
|
|
```
|
|||
|
|
- This should print the full path to `blender.exe`.
|
|||
|
|
|
|||

|
|||
|
|
|
|||
|
|
## **How to Fix**
|
|||
|
|
|
|||
|
|
- **Add Blender to the System PATH** (not just user PATH) on every worker machine.
|
|||
|
|
- **Restart** the worker process (and possibly the machine).
|
|||
|
|
- **Verify** in a new terminal that `blender` works before starting the worker.
|
|||
|
|
|
|||

|
|||
|
|
|
|||
|
|
## **Quick Fix: Hardcode the Path**
|
|||
|
|
|
|||
|
|
If you want a quick workaround, you can set the path in your `flamenco-manager.yaml` back to the full path for Windows:
|
|||
|
|
|
|||
|
|
```yaml
|
|||
|
|
variables:
|
|||
|
|
blender:
|
|||
|
|
values:
|
|||
|
|
- platform: windows
|
|||
|
|
value: "C:\\Program Files\\Blender Foundation\\Blender 4.4\\blender.exe"
|
|||
|
|
```
|
|||
|
|
|
|||

flamenco is showing only blender-boss and masterbox with no blender on path.
|
|||
|
|

|

---
|
|||
|
|
|
|||
|
|
_**Assistant**_
|
|||
|
|
|
|||
|
|
Given your output, you **can run `blender --version` successfully on `blender-boss` as your user**, so Blender is in your PATH in your interactive shell.
|
|||
|
|
However, Flamenco is still reporting that "no blender on path" for `blender-boss` and `masterbox`.
|
|||
|
|
|
|||
|
|
This is a classic case of **PATH differences between your interactive user and the environment in which the Flamenco worker runs**.
|
|||
|
|
|
|||
|
|
---
|
|||
|
|
|
|||
|
|
## Why This Happens
|
|||
|
|
|
|||
|
|
- When you SSH in or open a terminal, you get your user’s environment (including your PATH).
|
|||
|
|
- When Flamenco worker runs (especially if started as a service, via Task Scheduler, or by another user), it may have a different PATH.
|
|||
|
|
- If you added Blender to your PATH only for your user, or only in your current session, the worker process may not see it.
|
|||
|
|
|
|||
|
|
---
|
|||
|
|
|
|||
|
|
## How to Diagnose
|
|||
|
|
|
|||
|
|
1. **Check how the worker is started** on each machine:
|
|||
|
|
- Is it started by double-clicking, via a script, as a Windows service, or via Task Scheduler?
|
|||
|
|
- Is it started as your user, or as SYSTEM/Administrator?
|
|||
|
|
|
|||
|
|
2. **Check PATH for the worker process:**
|
|||
|
|
- Temporarily edit your worker’s `.cmd` or `.ps1` launch script to add:
|
|||
|
|
```powershell
|
|||
|
|
[System.Environment]::GetEnvironmentVariable("PATH") | Out-File -FilePath C:\flamenco_worker_path.txt
|
|||
|
|
```
|
|||
|
|
- Start the worker, then check the contents of `C:\flamenco_worker_path.txt` to see what PATH it actually sees.
|
|||
|
|
|
|||
|
|
3. **Compare this PATH to what you see in your terminal.**

## How to Fix
|
|||
|
|
|
|||
|
|
### 1. **Add Blender to the System PATH (for all users)**
|
|||
|
|
- Open System Properties → Advanced → Environment Variables.
|
|||
|
|
- Under "System variables", find `Path`, click Edit, and add the folder containing `blender.exe`.
|
|||
|
|
- Click OK, then **reboot** the machine (or at least log out and back in).
|
|||
|
|
|
|||
|
|
### 2. **Restart the Worker Process**
|
|||
|
|
- After updating the PATH, make sure to fully stop and restart the Flamenco worker process.
|
|||
|
|
|
|||
|
|
### 3. **If Using a Service or Task Scheduler**
|
|||
|
|
- Make sure the service/task is set to run as your user (or another user that has Blender in PATH), or that the System PATH is set correctly.
|
|||
|
|
|
|||
|
|
### 4. **(Optional) Hardcode the Path**
|
|||
|
|
- As a workaround, you can set the full path to Blender in your `flamenco-manager.yaml` for the affected machines.

|
|
| Blender in PATH for user only | Add to System PATH, reboot, restart worker |
|
|||
|
|
| Worker runs as different user | Add to that user’s PATH or System PATH |
|
|||
|
|

**TL;DR:**
|
|||
|
|
Blender is in your PATH for your user, but not for the environment the worker runs in.
|
|||
|
|
Add Blender to the System PATH, reboot, and restart the worker process.
|
|||
|
|
|
|||
|
|
If you want a script to print the PATH as seen by the worker, let me know!

oh wait, I forgot to restart their workers; the envs hadn't updated.

Ah, that's it! 🎯
|
|||
|
|
|
|||
|
|
**Environment variables (including PATH) are only loaded when a process starts.** Since you added Blender to the PATH after the workers were already running, they were still using the old environment without Blender in it.
|
|||
|
|
|
|||
|
|
After restarting the workers, they should now pick up the updated PATH and be able to find `blender`.

## What Happened:
|
|||
|
|
1. You added Blender to PATH ✅
|
|||
|
|
2. Workers were already running with the old PATH ❌
|
|||
|
|
3. Workers couldn't find `blender` because they had the old environment
|
|||
|
|
4. Restarting workers = they get the new PATH ✅
|
|||
|
|
|
|||
|
|

|
|||
|
|
|
|||
|
|
This is a super common gotcha with environment variables! Always remember:
|
|||
|
|
- **Environment changes** → **Restart affected processes**
|
|||
|
|
- Sometimes even need to restart the whole machine for system-wide PATH changes
|
|||
|
|
|
|||
|
|
Your workers should now be able to find Blender via PATH. 🚀

_**Assistant**_
|
|||
|
|
|
|||
|
|
This error from Blender:
|
|||
|
|
|
|||
|
|
```
|
|||
|
|
ERROR (gpu.vulkan): ...vk_index_buffer.cc:31 ensure_updated: Unable to allocate index buffer. Most likely an out of memory issue.
|
|||
|
|
```
|
|||
|
|
|
|||
|
|
means that **Blender’s Vulkan GPU backend is unable to allocate memory for an index buffer**. This is almost always a GPU memory exhaustion problem, but can also be caused by driver or system issues.
|
|||
|
|
|
|||
|
|
---
|
|||
|
|
|
|||
|
|
## What Causes This?
|
|||
|
|
|
|||
|
|
- **GPU out of memory**: The scene or job is too large for the available VRAM.
|
|||
|
|
- **GPU driver issues**: Outdated or buggy drivers can cause allocation failures.
|
|||
|
|
- **Vulkan backend bugs**: Blender’s Vulkan backend is still relatively new and may have bugs.
|
|||
|
|
- **System resource exhaustion**: If your system is low on RAM, swap, or GPU resources, allocation can fail.
|
|||
|
|
- **Headless/Remote/VM environments**: If running on a VM or without a real GPU, Vulkan may not work properly.

## How to Troubleshoot & Fix
|
|||
|
|
|
|||
|
|
### 1. **Check GPU Memory Usage**
|
|||
|
|
- Use Task Manager (Windows: `Ctrl+Shift+Esc` → Performance → GPU) or tools like GPU-Z to monitor VRAM usage.
|
|||
|
|
- If VRAM is maxed out, try a smaller scene or close other GPU-using apps.
|
|||
|
|
|
|||
|
|
### 2. **Update GPU Drivers**
|
|||
|
|
- Download and install the latest drivers from NVIDIA, AMD, or Intel (not Windows Update).
|
|||
|
|
|
|||
|
|
### 3. **Try OpenGL Backend**
|
|||
|
|
- By default, Blender 4.5+ may use Vulkan, but you can force OpenGL:
|
|||
|
|
- Run Blender with:
|
|||
|
|
```
|
|||
|
|
blender --gpu-backend opengl
|
|||
|
|
```
|
|||
|
|
- Or set the environment variable:
|
|||
|
|
```
|
|||
|
|
set BLENDER_GPU_BACKEND=opengl
|
|||
|
|
```
|
|||
|
|
- This can be set in your worker launch script.
|
|||
|
|
|
|||
|
|
### 4. **Check for Headless/VM Issues**
|
|||
|
|
- If running on a VM or server without a real GPU, Vulkan may not be supported.
|
|||
|
|
- Try using software rendering or OpenGL.
|
|||
|
|
|
|||
|
|
### 5. **Reduce Scene Complexity**
|
|||
|
|
- If possible, simplify the scene or reduce texture sizes.
|
|||
|
|
|
|||
|
|
### 6. **Increase System Swap/Pagefile**
|
|||
|
|
- If your system RAM is low, increasing the pagefile/swap may help (though this is a last resort for GPU memory issues).

## How to Set OpenGL for Flamenco Workers
|
|||
|
|
|
|||
|
|
**Edit your worker launch script or the environment for the worker process:**
|
|||
|
|
|
|||
|
|
For Windows PowerShell:
|
|||
|
|
```powershell
|
|||
|
|
$env:BLENDER_GPU_BACKEND = "opengl"
|
|||
|
|
blender ...
|
|||
|
|
```
|
|||
|
|
|
|||
|
|
For CMD:
|
|||
|
|
```cmd
|
|||
|
|
set BLENDER_GPU_BACKEND=opengl
|
|||
|
|
blender ...
|
|||
|
|
```
|
|||
|
|
|
|||
|
|
Or add this to your Flamenco worker’s `.ps1` or `.cmd` file before launching Blender.

|
|
|------------------------------|-----------------------------------------------|
|

|
|||
|
|
|
|||
|
|

|
|||
|
|
|
|||
|
|
**Try running Blender with the OpenGL backend and see if the error goes away. If it does, it’s a Vulkan/driver issue. If not, it’s likely a true out-of-memory problem.**
|
|||
|
|
|
|||
|
|
Let me know if you want a ready-to-use script or config for setting the backend for all your workers!
