Strange lighting issue on ceilings.

Okay, I made a map. It compiles fine. I have lights, light_spots, and
light_environment in my map, in addition to cubemaps. There are no
compile errors whatsoever. It compiles perfectly, but when I get
in-game to test it, the spawn area looks great. Then I go into the
hallways or this other room and the ceilings are either black, oddly
lit, flicker with movement, or flicker with gunshots (in certain random
directions). Here's a screenshot of one of the ceilings:



There is a light entity right in the center (not in the ceiling) and
see what it does to the ceiling? From a different direction, the
ceiling is completely black. And if I shoot certain directions or shoot
at it, it changes brightness. I'm so confused. I thought it was a
model, so I removed that. Then I figured it needed a cubemap, so I put
one... I've repositioned the light. I can't think of what else to do
that I haven't already done.

Thanks for reading, and thanks for the help (if you're able to help ><)

Even though you say it compiles perfectly, could you post the compile log? It seems like the only place to start.

Actually, I noticed one small issue. I'll bold it for you. Oh yes, and
it shouldn't be a big deal because I'm using buildcubemap in-game
anyway.

Yeah that cubemaps message isn't an issue.

I'm not sure what to tell you... I didn't spot anything that stands out.

Are you using texture lighting? It says "
[Reading texlights from 'lights.rad']

[45 texlights parsed from 'lights.rad']" and I'm not sure if that could be it.

Maybe someone else will know.

<span style="color: white;">Are using a texture on those ceilings that is intended for a model (Indicated by /model/texturename or /props/texturename in the model browser) as the anomailes you describe seem to coinside with a model texture being used.

CLs
</span>

Wow... Now I feel like a retard for not noticing. In fact, I tried
changing the texture before, but I changed it to another model texture!
I figured since it lists them, they're okay to use. But I was wrong.
Thanks for the solution... Although I'm not that happy about it. There
were some good textures.

<SPAN style="COLOR: white">I am pretty sure there is a way to convert a model texture for use as a normal texture. I believe it involves editing the VMT related to that texture, but in what way I dont know. (Someone around here does... :rolleyes: )

CLs

</SPAN>

Simply copy the vmt, rename it, and replace the first line with lightmapped_generic(I believe)
