I'm interested in exploring the light properties further. I am curious about the variables used in the DirectionalLight.js and SpotLight.js source codes.
Could you explain the difference between castShadow and onlyShadow?
Is there a way to manage the light so that it does not pass through objects? For instance, if I have a house with walls, can I control the light in each room separately?
I have come across the PointLight and it seems to be functioning properly. However, when I try to add more than 4 lights, they stop working. Are there any limitations on the number of lights that can be used?
