Lightmapping Settings

Controls baked lighting resolution, filtering, and ambient occlusion.

note

These settings affect all users on the currently active branch of the project.

Navigate to the LIGHTMAPPING section and expand the panel:

Here is a breakdown of the available settings:

General

Setting	Description
Size Multiplier	The resolution of auto-generated lightmap textures is based on the area of geometry in world space and the size multipliers of the model and scene. Changing this value affects lightmap resolution across the whole scene.
Max Resolution	Maximum resolution for auto-generated lightmap textures.
Mode	The lightmap baking mode: Color Only: A single color lightmap Color and Direction: A color lightmap plus dominant light direction (used for bump/specular)

Filtering

Setting	Description
Filter	Enable a bilateral filter on runtime-baked lightmaps.
Range	The range parameter of the bilateral filter.
Smoothness	The spatial parameter of the bilateral filter.

Ambient Bake

Setting	Description
Ambient Bake	Bake ambient light into lightmaps.
Samples	Number of samples to use when baking ambient light.
Sphere Part	The portion of the sphere to include when baking ambient light.
Occlusion Brightness	Brightness of the baked ambient occlusion.
Occlusion Contrast	Contrast of the baked ambient occlusion.
