Lighting question:

[et_cg]

Do portals affect lighting?

[Roostervier]

Not that I've seen so far, but I have not done advanced lighting yet. Maybe Sunny can help you.

Supersunny is a light from the gods. All the testing I've done has no real effect on the BSP.

I think portals effect how the lightmaps are broken up into their seperate sections, but do not effects the lighting itself. Hence, why large maps without portals get memory problems when running lightmaps.

Indeed you are correct! When you create portals and then do the lightmaps, each chunk or section broken off by the portalling is a separate bitmap in the lightmap bitmap tag. That way, Halo knows only to render that certain area :P

Actually, portals do affect lighting. Where their are portals, there are seams in the lightmap texture UVs. So you may notice some sharp edges in the lighting where the portals are.

Ahh, okay. I was looking for a way to better performance for a map I'm working on. It's still in the rough.

??? Appears fine for me. Maybe for baking lights? The engine can create lightmaps fine even if the UV's are auto set for the lightmaps, (pieces in different areas of the bitmap). Portalling shouldn't cause any problem.

jahrain, i noticed this too. but i think it depends on what u run the lightmaps at. i now run everything on medium and it turns out great. also, did anyone notice that if you have portals, tool creates multiple "light sources" or something. it says like:

...building lights. <light 1 of 4> <50&#37;>
built 4 lights.

or something like that?
i dunno.

Mine did that before I ever used portals.
