+
+Don't edit anything. just tell me what I should set my render settings to.
+
+---
+
+_**Agent (model default, mode Agent)**_
+
+
+
+---
+
+
+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.
+
+---
+
+_**Agent (model default, mode Agent)**_
+
+
+
+---
+
+
+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.
