Very strange lighting glitches - Only wi Created 14 years ago2010-08-20 21:43:59 UTC by supertanker

My map is having some ungodly weird lighting issues with opaque lightflags, but only in ZHLT 3.4 and higher (including the latest SHLT)--2.5.3 compiles fine.

Here are some screenshots:

Shots 3-4, and 6-7 are opposite sides of doors marked opaque. 1-2 are the same door. 5 is a light in an airduct that seems to only be casting halfway (it's the lower light, not the upper one, and isn't marked opaque or anything, but I thought I'd include it anyways). Note that 4 seems to cast a shadow across an area that should not have a shadow (the only light source is that one in the upper corner). Same with 7, since there's not really anything in the other room to cast light. (I'm not complaining about the cut-up light on the ceiling--I know that's because the light brush isn't a func_wall).

It's very confusing, and very annoying. I don't have any real reason not to go back to ZHLT 2.5.3, other than that I like running the latest tools, but if this can't be fixed, then I'm going to have to--there's no way I can have some of these doors not marked opaque, since they are very dark on one side and very light on the other.

Is there anything else I can try before going back to the old tools?

i've found all the zhlt light flags buggy and non-useful. They end up creating more problems than they fix.. =(

You can however tweak your lighting in subtle ways like using null-textured func_illusionaries to cast shadows, and other things that i'm sure i'm unaware of. You could also experiment between using textlights/pointlights/spotlights, as they all behave differently with how they cast shadows.

There is also the Translucent texture, that may be able to help you in certain situations, since it is like a func_illusionary as a world brush, and it blocks vis so it also blocks lighting and shadows..

hope helps! =)
