Hi Sergey Thanks for your answer.
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 changing only 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.
