L4D Streets Map( For Gmod) Screwed up texture?

Okay so i downloaded the map and once I joined i got a bit of a texture problem with the walls (And yes I do have a valid copy of L4D) http://img403.imageshack.us/i/l4dhospital01apartmentdr.jpg/

So it’s basically happening with all the brick walls and mostly in the streets but the apartment building texture walls are fine.
Any things to help me?

It’s because the lighting is different between games.

Hmm well hopefully the person who ported it fixes it cause the last 2 ported maps( Hospitle04, and the aiport) were fantastic, besides the random blue wall with the writing spawn point on it.

Map was not compiled with HDR, and probably cubemaps weren’t built

Correct ALL!

Yep, is it so hard to read the OP?
