Yes, thanks rjpieke

I got the “Magic of Houdini”-Book and made some 3DBuzz tutorials, but VOBs are a little rare!?

Now I will try to fuzz the edges a bit… hope to get it.

Thank you rjpieke,

so far the theory.

Everytime I try this, the result is depending by the view and not locked on global direction.
Don't know what is wrong, may anyone help a beginner ops:

Hi,

I`m still learning Houdini and try to build a Snow-Shader in VOBs.
The snow should lay an flat areas of a mountain and not on steeply faces.

So I need a ramp controlling the coverage, but how!?
