Topic: Clip mapping with displacement

have seen several comments about using V-Ray to create true clip mapped effects. I was wondering if those who were successful in doing so could please post a quick step-by-step. - Jay

Jay, it's a snap:

1) Create a plane with texture coords
2) Apply VrayDispalcementMod to the plane
3) Create a B&W or greyscale image (I used a clamped noise for this writeup)
4) Put the B&W image/noise in the Texmap slot of the VRaydisplace mod.
5) Check "Use water level" in the VRayDisplaceMod
6) Change the "Water level" to something other than 0
7) Render

The plane will be clipped based on the water level threshold...think of it as a greyscale threshold.

One thing to note, the water level should be less than the displacement "amount". For my example I used an "amount" of 0.01 (so as to have minimal height displacement), and a water level of 0.001 (to clip closest to black). The greyscale threshold goes from 0 (zero) to the amount of the displacement you set.
