Looks like I accidently found a bug related to Motion blur and with VRScenes. I managed to recreate the problem in a simple scene.
If I load a .vrscene cache file (saved from Houdini) and try to render using Motion Blur, using a Vray Physical Camera , an un-flipped version of my character get duplicated in the scene. For now we are rendering with velocity and making MB on comp but would be nice have this look into it. We are all using Vray 7.4 stable versions.
