Hi everyone. I made a destruction FEM simulation and i'm trying to render a MV Pass in Arnold to composite a little and practice a bit. My problème is I can't get a correct pass. --> I cached my simulation in bgeo file. Velocity attribut is present in my Load File Node when I import it after. --> I have an Arnold Shader with just just a motion_vector node. --> My camera has Arnold Properties with MOtion Blur activated. Same for the Geo sop. --> Rop node with MB activated as well. --> Every shutter speed at 0.5 (i tried to followed the Arnold Doc on Mvector pass but without success) With everything like this, i just end up with a full green shader, and nothing else. I tried to use it in Nuke with RSMB but nothing. I don't understand what I'm doing wrong. IF someone can give me a hint ! Many thanks I put the Hip file and the screen of my render.
