Is it possible to do global illumination / ambient light using a custom texture? Mapped out along the world X&Y axes? Applied to both static and dynamic objects.
I’ve done this approach before with OpenGL shaders so I could specifically paint colored lighting into specific places in the scene and have other areas darkened. Especially useful on mobile.
Using this for a sports field, where I want lighting focused on the field with colored sections, with the background getting darker. Ideally without fog or point lights.
