Missing Textures

[Lux]

Certain textures appear as the gray box with white grid on it. Textures affected include glass and various metals spread across all of the default maps.

What's going on? Only certain textures are missing.

A .pk3 in your base is corrupted.

I must agree.

Setting the cvar "developer" to 1 before loading the map will make it spam more text that may give you some insight (ie list the names/paths of the missing textures) that could tell you which file, but perhaps reinstalling would be best.
