Getting Started

Set up Spectral in a test project before changing a production level. The baker needs ray tracing, while the finished baked lighting can run on a different rendering configuration.

Setup order

1. Installation: install through Fab, enable Spectral, and configure shader hooks.
2. Platforms and systems: check baking requirements and runtime restrictions.
3. Interface: find the tabs and scene tools.
4. Saving settings: understand which changes belong to a level, project, or engine installation.
5. First bake: build lighting in a small level.

noteNote

Spectral provides its own lighting baker. Do not enable Unreal's GPU Lightmass plugin alongside it.
