Custom Textures Lighting Strangely

[kkirspel]

Alright, I've only just seriously started making my own textures and I've been getting this strange problem over and again:

The way this seemingly reflected box light is cast onto the walls. The only custom asset is the windows refract shader; no actual texture (this is a square room with light only coming in from a window in each corner)


Again with the boxes (in the darker portion). This is one on the new texture itself.


The only things I came up with was I: A. forgot something in the VMT file, B. suck at lighting, or C. suck at texturing.

Anyone see this before and know how to fix it?

This isn't a problem with custom textures and it happens often. I haven't really found a solution to it other than raising the lightmap scale.

You should post the VMTs.
Custom textures can be a bitch. One problem I often encounter is that lightning on func_detail is different from lightning on non-func_detail brushes.
Please post your VMTs.

That's just radiosity in the works there. You're trying to fill the room with indirect lighting with too few bounces.
I don't know if source even support enough light bounces to make that room look like the light is coming from a single source.

You'd need something like close to a thousand bounces to make it look natural...
Just use some standard lights in the inside and you'll be fine.

The VMT for the glass in the first picture.

Code: Select all

"Refract"
{
   "$normalmap" "MyTextures/stained glass_NRM"
   "$refractamount" "0.5"
   "$bluramount" 1
   "$surfaceprop" "glass"
}

For in second picture, the golden texture:

Code: Select all

"LightmappedGeneric"
{
   "$basetexture" "MyTextures/old_wall"
   "$bumpmap" "MyTextures/old_wall_NRM"
   "$surfaceprop" "plaster"
}

Its the bare bones for both of them really. If the VMT is the problem its b/c there is something missing...

I'm also just using one light source in both of those shots; an env_environment.

You should add one, two or even three low-brightness lights spread around the room. As WhiteDevil mentioned, that should solve the problem.

Yeah a few lights solved it. A little brighter than I'd hoped for though... guess I could technically use color_correction or somthin'
