driving displacement rendering with animation

Post by Rork » 04 Mar 2015, 21:34

Hi all,

Pretty sure I've seen this before, but I'm looking for a way to render/displace a model with displacement maps, based on animation of the object.
Think animated package with rendered wrinkles where the model 'compacts' on itself.

Not using mental Ray , so some form on render agnostic soution (or Arnold...) would be great.

cheers for any tips!

Uhm, just like that off the top of my head, expression from shape weights or controller transforms to displacement parameter?
(and/or to ICE driven displacements (see RRAY) to see it "live"?)

Hi, could you mean getting the tension on the surface of the object? I've made a compound like this a while ago, it's on rray (just called Tension). It does compressio too. Your get a scalar value fromt it that you could use to control the amount of displacement you apply (after some math range changes, clamp etc).

But never really used it so I don't know how well it works for such things!

Hi,

The ICE tool and demo scenes are great!
I already did a displacement test with them, driving squash and stretch with the ICE B/W gradient and some textures driven by a mixer in the rendertree. :-)

cheers for the plugin and tips!
