EXR can enable post-render denoising, but you need to enable the denoising passes when rendering.
|
||||
|
||||
- EXR stores multiple passes/layers in one file (denoising data, beauty, etc.)
|
||||
- EXR stores 32-bit float data (vs 8-bit PNG), preserving detail
|
||||
- PNG cannot store denoising passes, so denoising later isn't possible
|
||||
|
||||
Updating the render script to automatically enable denoising passes when EXR is selected:

Here’s what to set in Blender so you can denoise later:
|
||||
|
||||
## Render settings
|
||||
|
||||
### 1. Output format
|
||||
- Output Properties tab → Output section
|
||||
- Set File Format to OpenEXR or OpenEXR Multilayer
|
||||
- OpenEXR Multilayer is better if you need multiple passes later
|
||||
|
||||
### 2. Enable denoising passes
|
||||
- Output Properties tab → View Layer Properties → Passes section
|
||||
- Enable:
|
||||
- Denoising Normal
|
||||
- Denoising Albedo
|
||||
- Denoising Shadow (optional, helps quality)
|
||||
|
||||
### 3. Cycles denoising (during render)
|
||||
- Render Properties tab → Denoising section
|
||||
- Denoiser: OpenImageDenoise (or OptiX if on NVIDIA)
|
||||
- Enable Denoising
|
||||
- If using Passes → Data:
|
||||
- Enable Normal
|
||||
- Enable Albedo (optional if not using denoising passes)
|
||||
|
||||
### 4. Render passes to save
|
||||
- View Layer Properties → Passes → Data:
|
||||
- Enable Normal
|
||||
- Enable Albedo (if you want them as separate passes)
|
||||
- With OpenEXR Multilayer, passes are stored as layers in the file
|
||||
|
||||
## Why this works
|
||||
|
||||
- EXR stores all passes in one file
|
||||
- 32-bit float preserves detail
|
||||
- Denoising Normal/Albedo passes let you re-denoise later
|
||||
- You can denoise post-render in Compositor or with external tools
|
||||
|
||||
## After rendering
|
||||
|
||||
You can re-denoise later:
|
||||
- In Blender Compositor: load the EXR, use Denoise node with the passes
|
||||
- Or keep render denoising off during render and denoise entirely in post
|
||||
|
||||
Note: PNG cannot store denoising passes, so you can’t re-denoise PNG renders later. EXR is required for this workflow.

_**User (2025-11-02 23:49Z)**_
|
||||
|
||||
So, when I send to sheepit, denoising will be disabled if I use the tiling option (which splits the frame into 2x2, 3x3, 4x4, or 6x6 so multiple workers can render one frame simultaneously, then they are combined) but I need to denoise it because the results are so noisy.
|
||||

|
||||
|
||||
|
||||
For SheepIt with tiling, you can't denoise during rendering (denoising needs the full frame), but you can denoise the combined EXR frames afterward if you save the required passes.
|
||||
|
||||
## Render settings for SheepIt + tiling
|
||||
|
||||
### 1. Output format
|
||||
- File Format: OpenEXR Multilayer (or OpenEXR)
|
||||
- Required so denoising passes are saved per tile and combined
|
||||
|
||||
### 2. View Layer passes (critical)
|
||||
- View Layer Properties → Passes → Data:
|
||||
- Enable Denoising Normal
|
||||
- Enable Denoising Albedo
|
||||
- Enable Denoising Shadow (recommended)
|
||||
- View Layer Properties → Passes → Combined:
|
||||
- Enable Denoising Data (if available; some versions)
|
||||
|
||||
### 3. Cycles render settings
|
||||
- Render Properties → Denoising:
|
||||
- Denoiser: OpenImageDenoise (or OptiX if available)
|
||||
- Keep Denoising enabled in settings
|
||||
- Note: With tiling, denoising won't run during render, but passes will still be saved.
|
||||
|
||||
### 4. After SheepIt combines tiles
|
||||
You'll have EXR files with:
|
||||
- Combined beauty pass (noisy)
|
||||
- Denoising Normal pass
|
||||
- Denoising Albedo pass
|
||||
- Denoising Shadow pass (if enabled)
|
||||
|
||||
## Denoise the combined frames
|
||||
|
||||
### Option A: Blender Compositor
|
||||
1. Open a combined EXR in Image Editor or Compositor
|
||||
2. Use Denoise node:
|
||||
- Connect Combined (beauty)
|
||||
- Connect Denoising Normal
|
||||
- Connect Denoising Albedo
|
||||
- Optionally connect Denoising Shadow
|
||||
3. Export the denoised result
|
||||
|
||||
### Option B: External tools
|
||||
- OIDN (OpenImageDenoise CLI)
|
||||
- GIMP (with EXR support)
|
||||
- Natron or other compositing software
|
||||
|
||||
## Summary
|
||||
- Render EXR with Denoising Normal, Denoising Albedo (and Shadow if available)
|
||||
- Tiles will combine these passes into full-frame EXRs
|
||||
- Denoise the combined EXRs in post using those passes
|
||||
|
||||
This way you get fast tiled rendering on SheepIt and clean denoised results afterward.
