ILV = Indirect Light Volume.

I'm new to S&Box, I learned quite a bit code-wise and I really like the engine, but one thing that really disappoints me is the the Indirect Light Volume.

I'm a sucker for Indirect static lighting, as it can look really good while not destroying your FPS, and in every project that I develop I always use static lighting, but when I tried the Indiret Light Volume in my own project... It really disappoints me.
For whatever reason, there are these artifacts every single time whenever I bake the ILV. I did hear that I need a somewhat of an thick walls and all but the walls are thick enough, but that's not the only issue either.
It also creates artifacts like these, which again, its super annoying. I ran out of options, no one else seems to be having these problems for whatever reason, I entirely ran out of options and now I'm making this thread hopes of someone finally helping me with this.

Am I missing something entirely? Am I doing something wrong? Or is it something else?
