I never could get the Segment Editor to work.
I just do it manually.
It may seem like a troglodyte's way of doing it, but it works.
Post Script:
If you don't know how to do it manually, then you can wait for my next pack.
That is, if nobody else answers it here before then. (you'll still want the pack though)
Maybe we can trade Textures if you want or something. (I need more diversity too)
I'm working on it now, but I have my game release in a week, and Finals to study for too.
Once my game is released on the 7th, then I can devote all my time to the Pack.
I should have it done between the 10th and 14th of December.
It's going to be a Building Pack with Custom Walls and Floors, and a Tutorial on Segment Texturing.
The Segment Editor is really for changing the shapes of the Segments.
You don't need it to just change the textures of Walls and Floors.
