Blend textures

[royalkiller]

Hey TF2Maps community. I used every searching program on the internet, but I didn't found out how to use these blend textures. Everytime when I apply them, it just looks like this dirt. Can anyone help me please?
Thanks in advance.

You need to select the face(s) that have what you want, and turn it into a displacement. Then use the Paint alpha tool.

But remember always seal your displacements with a nodraw, because they dont count as world brushes.
