View Full Version : Help with displacement shader

04-27-2011, 03:41 AM
Hi all,
I'm trying to make a displacement shader to implement into a snow shader.
But it's not working the way I intended.
The shader I'm trying to make is here:
snow shader (

Below is the pattern I want to use as displacement.
Trying to apply the displacement into here.

Things that I've tried:
converting the pattern into HSV
converting the pattern into luminance
Using the fit node to decrease the displacement amount
Using the normalized node but it seems like displacement will not work after...

Someone please advise, thank you for your time.
for the file please visit:

The black artifacts are caused by missing displacement bounds, probably. You have to add them on the OBJ level via the gear-menu.

In the new production build there is a new Mantra surface node which fixes the displacement bound issues which were there before. You can check it out to see the proper setup for displacement and displacement bound.
