displacement Help please.

[pluMmet]

I've been watching VRay for a while and am wondering about it's displacement abilities. I know that in other rendering packages displacement causes the maps to stretch. If some one would use these two maps on a sphere to see how it works I'd be greatfull.

LoL

hey pluMmet, you can download the Vray demo and experiment a little for yourself. I think the stretching of the maps has to do with mapping coordinates - i'ts the curse of spherical mapping, don't you think?

Maybe unwrapping does the trick - but i'd say go ahead and try it for yourself. That's what the demo is for. Good Luck

Yea...that yellow one in the middle (particularly) and some of the others are wavy while the maps lines have at best a (one) slight curve...but yea. I didn't know there was a demo (i thought it was vray free( which I didn't think did dissplacement.)) but thx.
