About compositing
compositing is a Blender skill for assembling render passes into polished, delivery-ready images. It covers pass selection, a reversible beauty stack, restrained grading, and output validation for review or archiving.
Key features
- 01Render-pass selection and recombination
- 02Beauty compositing node stack
- 03Exposure and color grading guidance
- 04Subtle glare and lens effects
- 05EXR, PNG, and JPEG output guidance
- 06Delivery validation and settings documentation
Use cases
- 01Compositing Cycles or Eevee renders
- 02Adjusting exposure and color grade
- 03Isolating smoke, fire, or materials
- 04Preparing shot plates for review or archive

From the project READMECompositing
Pass-aware beauty stack. Subtle grade. Delivery-ready outputs.
When to Use
- Final beauty composites from Cycles/Eevee
- Grade, glare, vignette, chromatic subtlety
- Pass recombination (diffuse, glossy, volume, cryptomatte)
- Shot delivery plates
Workflow
Enable passes → Render multilayer EXR (or needed passes)
→ Compositor graph → Grade → FX (glare/fog glow)
→ Output viewer + File Output → Validate exposure
Recommended Passes
| Pass | Use |
|---|---|
| Beauty / Combined | Base |
| DiffCol / DiffDir / DiffInd | Relight flexibility |
| GlossDir / GlossCol | Spec control |
| Volume | Smoke/fire isolation |
| Cryptomatte Object/Material | Isolations |
| Mist | Depth grade / fog |
Beauty Stack (Default)
Combined
→ Exposure / Color Balance (AgX-aware)
→ Glare (fog glow / streaks sparingly)
→ Lens distortion (subtle)
→ Vignette (subtle)
→ Output
Grade Rules
- Fix exposure before creative grade
- Prefer lift/gamma/gain or color balance over crushed curves
- Keep skin/product hues plausible
- Match reference stills with side-by-side
Outputs
OUT_Beauty_[Shot]- Optional:
OUT_Alpha,OUT_CryptoID - Prefer EXR for archival; PNG/JPEG for review
Constraints
MUST DO
- Grade on view transform–aware pipeline (AgX)
- Keep creative FX reversible in node graph
- Document exposure/look settings
MUST NOT DO
- Crush blacks to hide lighting problems
- Over-glare every bright pixel
- Flatten multilayer to JPEG as only archive
