WTF?

[DnALANGE]

Maybe...
I've had smthing like this.. not the same but.. looked like it..
Do you have made any changes inside entities or Static object?
You maybe wanted to create you own entities ot change the Original ones?
And that didnt really worked out..
OR, you have been trying tio change values in a .ent \ .dea \ .mat?
-
As far as we \ i can see, it's that your walls are loading another .mat { .mat = material file }
You have messed up that specific wall\ or maybe more?
Can you tell us if you changed stuff yourself?
