I got some sort of a problem with the mental ray render proxies. I am currently rendering a scene where i am using grass as render proxies. When i enable them to render, it seams like the shadows of the sun (physical sun&sky) are missing. Even if the proxies arn not actually visible to the camera. I exported the gras to renderproxies, as described in the maya docs. Does anyone have the same problem or even better, the solution?
