Pick Cycles, Eevee, or Workbench for a render based on quality bar, time budget, and feature requirements (caustics, subsurface, etc.). Note: Eevee was named Eevee Next on Blender 4.2-4.x only.

Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.

What the file says

# cycles-vs-eevee-decision

## Purpose
Pick the render engine upfront based on quality + time tradeoff and feature requirements. Avoid the "use Cycles always" / "Eevee is faster" oversimplifications.

## Quick start
- Name the use case (hero / preview / animation / lookdev / flat clay).
- Evaluate required rendering features (caustics / subsurface scattering / volumetrics / global illumination accuracy).
- Evaluate time budget per frame and available hardware.
- Pick the engine: `Cycles`, `Eevee`, or `Workbench` (note: Eevee used the name Eevee Next and token `BLENDER_EEVEE_NEXT` on Blender 4.2–4.x only; it is `Eevee` with token `BLENDER_EEVEE` on 4.0–4.1 and 5.x).
- Pin the 4-item engine record: engine + samples + GPU device (if applicable) + caveats.

## When to use
- before render
- when feature support drives engine choice
- when time vs quality tradeoff matters
- when previous render was wrong engine

## When not to use
<!-- blendops:generated:start exclusions -->
- for a known repeat render (engine already chosen) → use `../lighting-material-plan/SKILL.md` (engine already chosen)

How to install

The exact contents, by fingerprint
mdr add thanhnguyxnorg/blendops/cycles-vs-eevee-decision@sha256:4335c3e578caa32d

The line at the top of this page pins the label git:20261103.3a68c5e, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
