# 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 scene.cycles.adaptive_threshold = 0.01 scene.cycles.adaptive_min_samples = 32 # Denoising (recommended) scene.cycles.use_denoising = True scene.cycles.denoiser = 'OPENIMAGEDENOISE' # safe default; switch to 'OPTIX' on NVIDIA RTX # Light paths (defaults are reasonable; bump transmission for glass-rich scenes) scene.cycles.ma
