[ART] Custom Wall Textures

[Daemian]

I don't know what you mean. Keep it square, scaled, full size, whatever.
Don't mind the black areas, just drop your texture, save it as dds and check how it looks in the editor, then you edit the image all you want until it looks good for you.

btw, remember you're using the default material(.mat) file for that texture (castlebase_wall.dds), so it's ok if you see spec and normals from the original texture. You may want to change that later if you have your own spec&normals.
