Vector Displacement

Those Things

Is it possible, currently in Iray, to use vector displacement? If not, are there plans to include it in the future?

Richard Haseltine

It isn't supported by the default shader (Daz Uber base), but I think it could probably be implemented via a custom shader. It was certainly possible to set it up in 3Delight via Shader Mixer.

I do 3Delight and aweSurface is already set up for vector displacement. But where to find these maps? Can you somehow convert traditional heightmaps or do you need to extract them from a mesh?

As far as I know, they're mesh-generated. Mudbox and Zbrush (and I think Blender?) can all generate and use them. I don't think conversion will work, because the vector data wouldn't be there to read.

Octane can too

and with the DAZ studio plugin

I sometimes render a normal vector to use with a 360 backdrop in programs that see them 

(including Octane)

to use on my subdivided 360 diffuse sphere in the vector displacement to give it shape, I particularly do this for iClone skies

I never thought of doing that, but it makes sense that it would be good for generating random, organic, displacements.

Tks! Very interesting topic, will look into it some more:)
