I want to use motion blur to blur the speed of a car passing in an animation. The thing is…I don’t want to blur the camera moving throughout the rest of the animation. Can I motion blur specific objects?
r.
maybe I’ll add to this. In viz with scanline rendering you can assign a blur to specific objects in the animation. This doesn’t work when rendering in vray. The blur rollout seems only to affect everything in the animation including the camera movement. I want to issolate the blur to a vehicle that passes and keep the camera movement blur free. Is this a photoshop job?
Selective MB isn’t in VRay yet but I think it’s on the wishlist…
Vlado?
i think there is a render effect motion blur you can try. i personally used to use an old trick from the ooooooold vray beta days when we had zero motion blur with vray. Basically i render everything normally in vray. then when im done i load that rendered version into the background as screen and change all objects to use matte shadow from max, and render scanline with image motion blur
Sounds cool elf, I’ll have to try it out 
Thanks,
