Vector Displacement is basicly only usefull when you are sculpting something and for this its perfect. You can take your mesh into scultping app, sculpt it in any possible way can think of and then render out Vector displacement map out if it. The result from Low Poly Cage + Vector Displacement map should be IDENTICAL to the High Poly Scuplted Model. I don’t know if zbrush and mudbox support proper vector displacement map generation but when they do this should be possible and it you should get it with a single press of the button.
The second case where its usefull is when you are programming some effects like sea surface.
<shrug> V-Ray is a rendering engine, not a modeller It can render the vector displacement, if you have the respective maps already, and it allows you to create your own maps in certain cases. Beyond that, it isn’t our purpose to create sculpting tools.
Ok, anyway if the vray vector disp. bake material could bake complex geometry and not only sculpted i think it will be much more useful.
I think the weakest point is this bake material.
Maybe in a future release we could see a more advanced version of this bake utility.
Yes now I understand better.
I thought that with vector displacement, I would be able to displace a normal map with infromation of all 3 azis( x,y,z) as rgb channels. I see that it is different than this.
When I want to make grass displacement with bend strands, d you think the most memory effcient method will be a normal map in bump slot?
there is one major limitation when using a vector displacement: you cannot adjust the map in secondary processing software like photoshop.
Often, when painting displacement you will go back and forth between the two. With vector map however there is no way to do that.
It can render the vector displacement, if you have the respective maps already, and it allows you to create your own maps in certain cases. Beyond that, it isn’t our purpose to create sculpting tools.
