Vertex-based lighting is technique to sample light at surface vertices and apply Gouraud shading during rendering.
Vertex lighting is most simple and fast lighting, it is used to store only low frequency data and will look bad at complex objects.
In Darkplaces engine, vertex lighting are part of map static lighting and being calculated each time map is compiled.
Usage of vertex lighting
| Small convex objects | OK |
| Foliage (grass, muchrooms etc.): | OK |
| Brush models: | Use with care, artifacts may occur |
| Whole map: | lots of artifacts |
| Terrain: | lack of shadows |
| Point entities: | not applicable |
