Blend multiple displacements problem

Konrad Curze

Hi!, sorry if this not the propper place to this therad i didn't know where to put it.

Im trying to blend multiple displacements into one mesh and it just dont work when i do the render it just come up flat :S

The main displacement map i applyed it by createing a plane, adding subdivisions and putting a displace modifier with a bitmap.

I've tryd all i know but im just a begginer in this.

What im trying to do is a landscape with diferent layers of grass ontop one another, but i want the extra detail and i need the displacement map in order to do that.

Thanks!





PD: sorry for my bad english xD

Have you been reading the Help file for V-Ray?
http://docs.chaosgroup.com/display/VRAY3/Default+Displacement#

Are you only rendering in Max? Or do you eventually want to export to a game engine? Different workflow is required for each.

Im only trying to render this on max, and yes, just finished reading the article and still i cant make it happen

What do the settings in your Displace modifier look like?

I would try the VRayDisplacementMod modifier, with a Composite map as the texture, and add the displacement maps in the Composite. This way you can use Masks for each layer, and you can experiment with layer blending modes (additive, screen, multiply, etc.).

I've made it, Thanks!

Didn´t had to use the VrayDisplacementMod, just the regular Displacement mod with a Heightmap and Composites hooked to a VrayMtl





It's just a test xD

Great!

You should look into VRayDisplacementMod or DispApprox, so you can avoid those low-resolution spikes.
