Motion Blur

[instinct]

be sure not to increase subdivs/samples in the render rollout. leave them at good settings for the SCENE not the blades, and raise the subdivs for the blades in their vray properties. Otherwise you'd oversample the whole scene without the neccessity to do so.

its interesting, but with scanline, you can give an objects properties 'object' motion blur and after turning on motionblur in the effects rollout, you get 'proper' 2d moblur on an object basis. For some reason, vray does not respect this. If you turn on motionblur in the effects rollout, you in effect get 'image motion blur' only. Surely this is a bug? I need some flying birds to only have motion blur and vray is forcing image moblur regardless of what I try. Of course I plan on rendering out to a separate pass, so I can get around it, but for tests, I really just wanted the birds to be properly moblurred without having the entire image moblurred.

couldn't you select all the objects except for the blades and overide the vrayproperties global mblur geometry samples and set it to 1. Wouldn't that effectively turn off the motionblur for everthing but the rotors? I suppose this would only work if the camera weren't moving.
