blender-rendering skillA
blender-rendering is agent-read markdown (skill) from max-786/claude-3d-harness: Render Blender scenes with the right engine and settings — Cycles for photoreal, EEVEE for speed/stylized, sample counts, denoising (OptiX/OIDN), light path tuning, color management (AgX/Filmic), file output (PNG/EXR/MP4), animation rendering. Use whenever the user asks to "render this", "produce an image", "render a frame / animation", "make a final image", "save the render", or any output-generation request. Make sure to use this skill even if the user does not say "render" — also covers "make.
Indexed from public GitHub and served as immutable, content-addressed versions. Install it pinned to an exact SHA-256 with the mdr CLI, and every file is verified against the hash recorded here before it reaches your agent. The deterministic audit below grades the latest version, and the same file always earns the same grade.
What the file says
# Blender Rendering
Render efficiently. The defaults are wrong for production; the recipes below are tuned for the common cases.
## Engine decision tree
```
Need photoreal? Caustics? Accurate SSS? Glass-rich?
├── YES → Cycles (path tracer)
└── NO → Need speed? Stylized look? Animation iteration?
├── YES → EEVEE
└── NO → Cycles (default fallback for photoreal)
```
**Quick rule**:
- Stills, archviz, product, hero shots → **Cycles**
- Animation previews, motion graphics, stylized → **EEVEE**
## Reference-look handoff
If the goal is to match an original/reference image rather than make a generally attractive render, chain-load `reference-look-calibration`. It owns measurement of hue/saturation/value, object extent, glow/aura color, and before/after look metrics. This skill should then apply the requested material/lighting/render changes within that calibrated target.
## Recipes
### Recipe 1 — Cycles production preset (256 samples + denoise)
```python
import bpy
scene = bpy.context.scene
scene.render.engine = 'CYCLES'
scene.cycles.device = 'GPU'
# Sampling
scene.cycles.samples = 256
scene.cycles.use_adaptive_sampling = True

How to install
mdr add max-786/claude-3d-harness/blender-rendering@git:20260921.d4bf893mdr add max-786/claude-3d-harness/blender-rendering@sha256:2c5fc68dd34f7951Pin to a label to follow the author's releases, or to a sha256 to freeze the exact bytes forever. Either way the resolved hash is written to mdr.lock, and mdr install reproduces it on any machine.
