Model/brush intersection is ok? Created 16 years ago2007-09-05 09:05:49 UTC by Blitzkrieg

Are there any performance ramifications to having parts of a model inside a brush? What about a brush cutting into a displacement? A model in a displacement?

No performance issues. The engine sees every part of the model as long as it sees something. I assume you are talking about prop_static entities. Having parts of a model inside a brush is very common, but since models are lit with vertex lighting, having a prop be inside more than one brush will get you inaccurate lighting.
Try making a long pipe and having it pierce through some brushes. You'll see what I mean.

Can't that problem with light be got around with the "info_lighting" ?

I know that if a model is to far into a brush (mayby the models origin is what metters here) it will be completly unlit unless you give it an info_lighting.

I do know what you mean, Kasberg. I have two huge windows who's borders stick slightly into the walls on either side, and the faces that the model sticks into are very dark. Now I can either adjust the brushes, and demolish what sense of symetry my pathetic building has, or do that info_lighting trick. What is that?
