|
A server that provides a way to store static lights that can be used to bake lighting information into mesh vertex data, or [SpatialMaterial]'s albedo modulation.
|
|
With this class extremely complex light information can be stored and used with no additional cost on the GPU side.
|
|
After adding lights, you can use [member sample_light] to sample lighting at a specified point in the map's space, then use the resulting [Color] to either further modifty the albedo color in your shader, or you can bake vertex colors of your meshes.
|
|
The drawback of this method is that it's more expensive change lights.
|
|
Note that you can use the normal 3D lighting system on top of this if you need dynamic lights (like [OmniLight]). That system is better suited for that purpose.
|
|
Currently this class stores lights inside quadrants. Their optimal size should be a bit more than the radius of the biggest light you want to have.
