Question
My game is basically made up of lots of PlaneMesh with materials and shaders on it that create the textures. These meshes are then arranged in a 3D space and interact with the DirectionalLight3D and the WorldEnvironment.
I would like to introduce some light and glow effects produced by some of these MeshInstances, and they should interact with the surroundings and add to the effects produced by the basic lighting.
I can modify the materials and shaders so that they emit light, but once placed in the game world with the WorldEnvironment they do not interact with other objects, they only change color.
The game at the moment is very light, for the scene is about a hundred PlaneMesh with cull back. The camera is fixed near the world and there are about twenty moving meshes on the screen. Some of these moving objects should emit light, so the lighting will have to be dynamic, but at the same time I would like to keep the game light.
Where can I start to get my bearings and figure out how to achieve these results? Any suggestions?
At the moment I found this article in the documentation, but I don’t know anything about these things and I’m afraid of taking a wrong path:
