Pre-Generate Locally Before Sync** +```powershell +# Force Windows/Icaros to generate thumbs BEFORE Drive Client touches files +# Copy files to temp local folder first, let thumbs generate, then move to Drive Client folder +``` + +**2. Exclude Thumbnail Cache from Sync** +- Configure Drive Client to exclude `Thumbs.db`, `@eaDir`, thumbnail cache folders +- Let Windows handle thumbnails independently + +**3. Force Regeneration After Sync** +```powershell +# Clear Windows thumbnail cache and force regeneration +Remove-Item "$env:LOCALAPPDATA\Microsoft\Windows\Explorer\thumbcache_*.db" -Force +# Then browse folders to trigger Icaros +``` + +**4. Use SMB for Browsing** (Your Best Option) +Since SMB thumbnails work perfectly, use Drive Client only for sync, SMB for daily browsing. + +You're right - the server-side approach I suggested doesn't solve your actual Drive Client problem at all. The issue is Windows-side thumbnail interference, not server-side thumbnail availability. + +--- + +_**User**_ + + + +--- + +_**Assistant**_ + + + +--- + +I see the issue with the SSH command I provided earlier.

The `${0%/*}` removes the last part of the path, `@eaDir` gets appended + +**Alternative simpler approach** (if you want to do it step by step): +```bash +# First, see what will be renamed (dry run) +find /volume1/Hydra/YouTube/Streams/MixerTwitch -type d -name 'eaDir_tmp' + +# Then rename them +for dir in $(find /volume1/Hydra/YouTube/Streams/MixerTwitch -type d -name 'eaDir_tmp'); do + mv "$dir" "$(dirname "$dir")/@eaDir" +done +``` + +--- + +_**User**_ + +and is this commensorate with this workflow? + +--- + +_**Assistant**_ + + + +--- + +Yes, but the **README.md command is actually incorrect**!

Here’s how it works and what you can do: + +### Why Blender Thumbnails Sometimes Don’t Work +- Blender only generates thumbnails for `.blend` files under certain conditions (like saving with a camera view, or with the right settings). +- Sometimes, Windows Explorer or other file managers don’t update or show these thumbnails correctly. + +### Using Your Own Thumbnails +If you have your own PNG or JPG images that you want to use as thumbnails for your `.blend` files, you can manually set them in Windows. However, Windows does not natively support custom thumbnails for arbitrary file types like `.blend`. But you have a few options: + +#### 1. Thumbnail Overlay Tools +There are third-party tools (like **SageThumbs**, **Icaros**, or **CustomExplorerThumbnail**) that let you assign custom thumbnails to files, including `.blend` files. + +#### 2. Folder Thumbnails +If you want to visually organize your folders, you can set a folder’s thumbnail to one of your images: +- Right-click the folder → Properties → Customize → Choose File (under Folder pictures). + +#### 3. Preview Images in File Explorer +If you want to see a preview of your `.blend` file, you can: +- Keep a PNG/JPG with the same name as the `.blend` file in the same folder for easy reference. +- Use a file manager that supports side-by-side preview (like **Directory Opus** or **XYplorer**). + +#### 4. Custom Scripts (Advanced) +You can write a script to generate a Windows shortcut (`.lnk`) for each `.blend` file, and set the shortcut’s icon to your custom image. This is a workaround, but not a true thumbnail. + +--- + +**Summary:** +You can’t natively set custom thumbnails for `.blend` files in Windows Explorer, but you can use third-party tools or keep your generated thumbs alongside your `.blend` files for easy reference.

You can easily create a local Git repository on your NAS to use as a remote for your project. Here’s a concise step-by-step guide: + +--- + +## **1. SSH into Your NAS** + +Open a terminal and connect: +```bash +ssh nathan@hydra +``` + +--- + +## **2. Create a Bare Git Repository** + +A "bare" repo is used for sharing (no working files, just the `.git` data): + +```bash +mkdir -p ~/git/synology-thumbgen.git +cd ~/git/synology-thumbgen.git +git init --bare +``` + +- This creates a remote repo at `~/git/synology-thumbgen.git` on your NAS. + +--- + +## **3. Add the NAS Repo as a Remote on Your Local Machine** + +On your Windows machine, in your project folder, run: + +```bash +git remote add nas ssh://nathan@hydra/~/git/synology-thumbgen.git +``` + +- If you already have a remote named `nas`, you may need to use `git remote set-url nas ...` instead. + +--- + +## **4. Push to Your NAS** + +```bash +git push nas master +``` + +--- + +## **Now you have a private, local Git remote on your NAS!** + +You can push/pull as needed, and even clone from other machines on your network. + +--- + +**Let me know if you want a script for this, or if you hit any permission issues!** + +--- + +_**User**_ + +what next? + +--- + +_**Assistant**_ + +Perfect! Your bare Git repository is now created on the NAS at `/volume1/git/synology-thumbgen.git`. Here's what to do next: + +--- + +## **3. Add the NAS Repo as a Remote on Your Local Machine** + +On your Windows machine, in your `synology-thumbgen` project folder, run: + +```bash +git remote add nas ssh://nathan@hydra/volume1/git/synology-thumbgen.git +``` + +--- + +## **4. Push Your Current Code to the NAS** + +```bash +git add . +git commit -m "Initial commit: Synology thumbnail generator" +git push nas master +``` + +--- + +## **5. Verify It Worked** + +You can check that your files are now on the NAS: + +```bash +ssh nathan@hydra "ls -la /volume1/git/synology-thumbgen.git/objects/" +``` + +--- + +## **Now You Have a Local Git Remote!** + +- **Push changes:** `git push nas master` +- **Pull changes:** `git pull nas master` +- **Clone from another machine:** `git clone ssh://nathan@hydra/volume1/git/synology-thumbgen.git` + +This gives you version control and backup for your thumbnail generator project, all stored locally on your NAS! + +--- + +_**User**_ + +one of my previous repos checkout to \\Hydra\git\writinRepo.git + +--- + +_**Assistant**_ + +Ah, I see! You're using a **network share** (`\\Hydra\git\`) instead of SSH for your Git remotes. That's actually simpler and more convenient on Windows. + +--- + +## **Use the Network Share Instead of SSH** + +Since your other repo uses `\\Hydra\git\writinRepo.git`, you should use the same pattern: + +```bash +git remote add nas \\Hydra\git\synology-thumbgen.git +``` + +--- + +## **Then Push to Your NAS** + +```bash +git add . +git commit -m "Initial commit: Synology thumbnail generator" +git push nas master +``` + +--- + +## **Why This is Better** + +- **No SSH authentication** - uses your Windows network credentials +- **Faster** - direct network access instead of SSH tunneling +- **Consistent** - matches your existing workflow with `writinRepo.git` + +--- + +## **Your Remote URL** + +Your remote will look like: +``` +nas \\Hydra\git\synology-thumbgen.git (fetch) +nas \\Hydra\git\synology-thumbgen.git (push) +``` + +This is much cleaner than the SSH URL! You can now push/pull just like your other repos. + +--- + +_**User**_ + + + +--- + +_**Assistant**_ + +Perfect! Your Git setup is now complete with both remotes: + +- **`origin`** - Your GitHub repository (for public/sharing) +- **`nas`** - Your local NAS repository (for private backup/version control) + +--- + +## **Now You Can:** + +### **Push to Both Remotes** +```bash +git push origin master # Push to GitHub +git push nas master # Push to your NAS +``` + +### **Or Push to Both at Once** +```bash +git push --all origin nas +``` + +--- + +## **Typical Workflow** + +1. **Make changes** to your thumbnail generator +2. **Commit locally:** `git commit -m "Description of changes"` +3. **Push to both:** `git push origin nas` +4. **Or just NAS:** `git push nas master` (if you want to keep it private) + +--- + +## **Benefits** + +- **Backup:** Your code is safely stored on your NAS +- **Version Control:** Track changes and rollback if needed +- **Sharing:** Still push to GitHub when you want to share +- **Offline:** Can work on your NAS repo even without internet + +Your thumbnail generator project is now properly version controlled with both local and remote backups! + +--- + +_**User**_ + +the original repo isn't mine + +--- + +_**Assistant**_ + +Ah, I see! The `origin` remote points to someone else's repository (`mbrrg/synology-thumbgen.git`), not yours. That's common when you fork or clone someone else's project. + +--- + +## **Your Current Setup** + +- **`origin`** - The original author's repo (read-only for you) +- **`nas`** - Your local NAS repo (your private backup) + +--- + +## **What This Means** + +- You can **pull updates** from the original repo: `git pull origin master` +- You can **push your changes** to your NAS: `git push nas master` +- You **cannot push** to the original repo (unless you have write access) + +--- + +## **If You Want Your Own GitHub Repo** + +If you want to share your improvements publicly, you could: + +1. **Fork the original repo** on GitHub (creates your own copy) +2. **Add your fork as a new remote:** + ```bash + git remote add myfork https://github.com/YOUR_USERNAME/synology-thumbgen.git + ``` +3. **Push to your fork:** + ```bash + git push myfork master + ``` + +--- + +## **For Now** + +Your NAS repo (`nas`) is perfect for keeping your personal improvements backed up and version controlled. You can continue developing and pushing to your NAS without affecting the original project. + +--- + +_**User**_ + +can i make it so commits, etc only goes to my nas? + +--- + +_**Assistant**_ + +Absolutely! You can make your NAS repo the default so all commits and pushes go there automatically. + +--- + +## **Option 1: Set NAS as Default Remote** + +```bash +git remote set-url origin \\Hydra\git\synology-thumbgen.git +git remote rename origin nas +git remote add upstream https://github.com/mbrrg/synology-thumbgen.git +``` + +This changes your setup to: +- **`origin`** (default) - Your NAS repo +- **`upstream`** - The original author's repo + +Now `git push` and `git pull` will use your NAS by default. + +--- + +## **Option 2: Keep Current Names, Set Default Branch** + +```bash +git branch --set-upstream-to=nas/master master +``` + +This makes `git push` and `git pull` use the `nas` remote by default, while keeping your current remote names. + +--- + +## **Option 3: Configure Push Default** + +```bash +git config push.default current +git config branch.master.remote nas +``` + +This tells Git to push to the `nas` remote by default. + +--- + +## **Recommended: Option 1** + +This is the cleanest approach - your NAS becomes your "origin" and the original repo becomes "upstream" for pulling updates. + +**After this, you can:** +- `git push` → pushes to your NAS +- `git pull` → pulls from your NAS +- `git pull upstream master` → pulls updates from the original repo + +--- + +_**User**_ + + + +--- + +_**Assistant**_ + +I see the issue - you already have a `nas` remote, so we can't rename `origin` to `nas`. Let's fix this: + +--- + +## **Remove the Duplicate and Set Up Correctly** + +```bash +# Remove the old nas remote (since we're making origin point to NAS) +git remote remove nas + +# Now rename origin to nas +git remote rename origin nas + +# Add the original repo as upstream +git remote add upstream https://github.com/mbrrg/synology-thumbgen.git +``` + +--- + +## **Or Keep It Simple - Just Update Origin** + +Since you already set `origin` to point to your NAS, you can just remove the duplicate `nas` remote: + +```bash +git remote remove nas +``` + +Now you'll have: +- **`origin`** - Your NAS repo (default) +- **`upstream`** - The original author's repo + +--- + +## **Check Your Remotes** + +```bash +git remote -v +``` + +You should see: +``` +origin \\Hydra\git\synology-thumbgen.git (fetch) +origin \\Hydra\git\synology-thumbgen.git (push) +upstream https://github.com/mbrrg/synology-thumbgen.git (fetch) +upstream https://github.com/mbrrg/synology-thumbgen.git (push) +``` + +Now `git push` and `git pull` will use your NAS by default! + +--- + +_**User**_ + + + +--- + +_**Assistant**_ + +Perfect!
