is there, or will there ever be, a utility tool that simulates light bounces and automatically divides sectors into small sectors of differing light levels?
it really feels like something that should be possible to automate. obviously it won't be as good as the real deal, as sometimes you'll want very unique lighting that can't be just calculated on the fly, but i feel like it would save a lot of time regardless.
