I've started to create an 4K texture mod to ''Left 4 Dead 2'' and everything was going fine, as you can see here:


But some textures are stretched:



I been able to fix some of them with this code:

"$basetexturetransform" "center 0 0 scale 10 10 rotate 0 translate 0 0"

But this code don't fix all textures. I need help to continue my mod.
Someone know how to fix this?
