Door texture problem

[Idiots Playing GamesTM]

The door texture doesn't load when the door is closed. It loads anywhere else, but not when closed. What did I do wrong?

Could you send the WAD? It's much easier to find the problem that way.

I've noticed this happens when door texture is not applied correctly. Make sure that if you lowered the ceiling for door, the texture is in "Upper" part of the linedef textures.  If you heightened the floor for the door, make sure the texture is in "Lower" part of the linedef textures.

 

Basically, your texture is in wrong location most likely. 

Also, please be kind to post your wad. If the textures are fine then something else may be wrong, and more experienced mappers can not help you without it.
