hi from spain and excuse me for my bad english. In this map that i'm working i have any lights with any zone. Only moving a few the player the textures lightings go to black or very dark. Why? Thanks

I first thought it was an error in the compile tools, until later I learned it was to do with the shader used on the material.

Look at the materials chosen for the surfaces that get darker/lighter and check for "prop" or "model" in the name. Any texture designed to be used on a model uses a different shader and will not work properly on world geometry.

The same problem with more explinations can be found here:

Use the Hammer "replace texture" tool to replace any texture with "model" or "prop" in the name with a similar texture without those names.

In the future, when you're browsing textures, don't select any that reads "models\..."

thanks
