I am trying to figure out the whole prop and texture editor to deco my zaby. The tutorial is woefully inadequate, and not entirely accurate, as with sign instructions. I am trying to add texture to walls that I have created. Seems like it should be simple, but it doesnt work like adding texture to the existing zaby walls from the editor. And the tutorial makes no mention of it.

Can someone tell me the procedure? I'm trying to make a border wall around an area, made of brick with clinging ivy.

thanks
