Bump mapping
 

I know it was possible in Vizard 3.0 but I can't find any documentation about it in Vizard 4. Also using the Vizard 3.0 command in Vizard 4.0 doesn't seem to do anything or I'm just doing it wrong :)

Are you referring to the .bumpmap command? It's not documented, but it should still be available in Vizard 4.0.

Yes that's the one.

I apply it to a Quad and than apply the texture to it but there seems to be no effect. If i switch the order around (so first the texture and then the bumpmap command) the bumpmap image is used as texture on the plane or so it seems.

What are the requirements for the bumpmap image file? Now it's a single layer gray scale image.

The command uses a normal map. Normal maps usually are a bluish color. It sounds like you have a height map.
