Describe your enhancement suggestion in more detail
Consider adding a compiler-only brightness multiplier to light entities (especially clustered lights), such that they can be set via instance parameters. The final compiled result may still be the same as it currently functions, with the multiplier parameter gone and further changes needing to be made via the existing color and brightness keyvalues.
It'd default to 1.0 and would simply multiply the existing _light brightness during compile.
Currently, there is no way to dynamically define the brightness of lights in instances via instance parameters without also overriding their colors. Brightness can be changed with dynamic lights via scripting, but not with static lights.
