attrobute colorto control displacement

[vbk!!!]

hello,

I would like if it's possible to use attribute to displace a mesh.

I watched the attribute transfert tutorial series in the sidefx site :

I wonder how to use the color attribute transfered to the grid to displace it.

Thanks for your help

Are you talking about deforming the geometry in SOPs, or in the render?

if your trying to do it as part of a sop you could use a vop sop. just connect an import attribute node to a displace along normals node and connect the dispP and dispN from the displace normal node to the p and n outputs.

thanks for the replies

I am talking about displacement in the render

I made some test with vopsop already but it seems it is not that easy to make the same kind of things in microdisplace during the render.

Thanks for your help

Yup, same thing can be done at render time. I usually setup a material in a SHOP then it can have VOP displacement shader and a VOP surface shader for the output. The displacement is calculated first. If using micropolygon rendering you'll probably have to increase the dicing on the object level to get small details from the displacement (or just use ray tracing renderer). Cheers!
