The first sign of something being wrong with my map was when I loaded it and I got this:

This is the shader:

Code: Select all

textures/wodensky/wodensky
{
   qer_editorimage textures/wodensky/wodensky
   surfaceparm noimpact
   surfaceparm nolightmap
   q3map_globaltexture
   q3map_surfacelight 60
   surfaceparm sky
   q3map_sun 1.00 1.00 1.00 250 135 60
   skyparms env/wodensky/wodensky - -
}

I thought there might be something wrong with it, so I removed it from the shader list. Result? The Light compilation quit working on the first bounce (of 8 ), and the result was a map that wouldn't load.
Nexuiz gave me the following error messages:

Code: Select all

Collision_Validatebrush: brush with no points
Collision_Validatebrush: all points lie on all planes (degenerate, no brush volume)

Host_error: Mod_q3BSP_loadlightgrid: invalid lightgrid lumpsize (big number) bytes should be (bigger number) bytes.


If I turn off both the -bounce switch and the shader, the map compiles and loads normally, there is no Host_error, and it looks the way it should (but no bouncy lights and no skybox). But I still get the Collision_Validatebrush error messages. Lots of them. Plus a bunch of numbers for each message.

I took a closer look at the BSP compilation log and found this:

Code: Select all

############### model 0 ###############

How do I find model 0? As for entitiy 28, it first said entity 20 (which was a model) until I deleted it. Entity 28 is yet another model. More whackamole.

Anybody have a clue here? There is something wrong with my map, but I can't figure out what.

(btw: Used the brush cleanup plugin - it can't find anything wrong)

Make a hollow 3d triangle pyramid of caulk.
Put the map inside of it.
Make each side of the triangle pyramid 60000 quake units per side.

Huh?

Anyway, if found the problem; turns out I had inadvertently created a gigantic skybox, and it made the light compiler barf. Problem solved.
