Lightmap issues

[Cheomesh]

I was following a tutorial that had me put in light entities farily early on. It then had me build off this by making the light turn on and off with a switch, etc.

I noticed around that time I had issues with walls randomly going black and then being lit again. As I continued it annoyed me a lot so I removed the switch just in case that had anything to do with it (they defaulted to off, and the blackness issue began when you turned the lights on); it didn't help, so I deleted all the light entities and put in new ones.

The new ones however, put off a glow around where they are in the map, but all the walls are black, except for the "door".

If anyone can help, PM me and I'll send the VMF -- I'm out of ideas as I've run through all the settings, tweaking pretty much everything, and then redoing what he had in the tutorial to no help.

Check you haven't used a prop texture. That usually makes textures turn black / light randomly.

Changed the textures around and it seemed to have fixed it, but then on one of my later compiles a section of the new texture stays black.

Try compiling with normal settings for vrad, what will improve shadows, check it isn't a prop texture again ("prop" in the texture name), check anything is blocking light and if everything else fails use a dim light entity to fake light :S

And if you have any problems with models being lit in a bad way, type buildcubemaps in console.

btw some textures look black with hdr, try with ldr to see if it is that case
