- For
- Blender artists testing advanced lighting and rendering
- Worth noticing
- Guiding runs on Metal, CUDA, and OptiX, but the page warns it can add render time when direct light dominates.
Field notes
The added controls sit inside Cycles, and the page says each can be left off so rendering behaves as before. Reblend reads and writes ordinary .blend files and uses Blender 5.2’s settings folder, carrying over preferences and add-ons. Requirements differ by platform: Apple silicon on macOS, Windows 10 or 11, or x86-64 Linux with glibc 2.28 or later. The project labels itself experimental and advises trying scene copies.
