Displacement mod edges

[Tim Saunders]

anyone know of a way to "lock" the edges of the displacement to the ground? i'm just trying to figure out how to avoid the black openings of these boulders.

Just try with meshsmooth BEFORE Vray displacement..........

Meshsmooth with 0 itenerations.

thanks to both. i'll try that.

well, i noticed a slight difference, but there were still some black edges. i had better results by fixing my texmap in ps. i just tiled the texture the number of times the patch of rocks needed in the scene, then made a black arc with a slight gradience, and blacked out a few of the rocks near the edge of the arch. that's working pretty good.

the other thing to try is to use the "shift" option with a negative number. This will essentially move the object down while displacing up.

One recommendation I've often read on the Chaos boards but never had to implement myself is to add a black border around the edges of your displacement map -- this will force all sides to return to the zero of the displacement. Hope that works for ya!

right i've seen that tip too for rugs. that's where i got the idea to photoshop a black arc that would go along the edge of the rock patch.
