Hi Sergey ! 26 octobre 2015 14:14 "Sergey Sharybin" a écrit:If it's just distinguishing whether there is motion or not then guess object space would work. Perhaps could be something similar implementation to the pointyness, but would nice to investigate if we can make it something more generic. 100% agree with you for the more generic thing. However, one question : is this velocity attribute on the vertices should be relative to the camera shutter of the scene ? Will check on that in the upcoming days. By the way, i'm glad that you're curiouse about this functionality ! I'm also trying to look at the code but i'm a very very beginner so I've got no hope to solve this on my own at the moment.
So thanks again ! Manuel Rais Autour de Minuit [email protected] (mailto:[email protected])On Sun, Oct 25, 2015 at 11:44 PM, David Fenner wrote: Hey. Nice idea to simulate stop motion.

To be more clear, we want to use this attribute to switch from a texture to another when the velocity is not null. The purpose is to have a stop motion rendering with displace/bump changingonly on the moving parts. Of course there's many ways to achieve this but we're searching the more automatic. We have others ideas of course but less funny ☺.. All objects in this project are baked in pc2 files and are at the center of the world and their scale at 1. So I guess the world space and object space are the same, but maybe I'm wrong. I know a little bit of c/cpp maybe I can produce a patch (with a little help?) if it's not too hard... Thanks.

Also, due to instancing it's quite tricky to represent word-space velocity in the vertex attribute, only object space velocity is possible to be stored without major PITA.

Cycles outputs velocity in the "Vector" pass, it renders motion blur (object and deformation), so I guess that this attribute exists somewhere...Am I wrong ? Is it possible to add it in the output of the attribute node ? Is it anightmare ?
