When using texture-based displacement on a mesh, I’ve found that the vertexes are always displaced relative to their faces’ normals. Is there a way to make vertices be displaced only along the z axis?
Hi,
It’s not as flexible as displacement mapping (it’s permanent for a start) but I think the Noise function displaces only along the Z-axis. If you want a one-off displacement it might be good enough.
The noise function is what you would want.
Displacement in all apps work this way. What you need is a map that would allow you to control direction of displacement and someone to put that into Blender.
Well, the new displacement modifier in the CVS can displace in only one axis.
