interstellar Posted May 25, 2015 Report Share Posted May 25, 2015 Years ago I read that you should never use Motion Vector blur when rendering ray-traced shadows. Is that still true? I'm rendering a project in passes; in one pass a single asteroid flies past the camera. There is nothing else in this pass except for the asteroid. There are two Shaders on the asteroid: Fractal Noise and Rust. When I render it in Ray Trace mode with Motion Vector enabled, the blur looks fine. This will be a long render-pass so I want to make sure it is set up correctly. Is combination of Motion Vector and Ray Traced shadows okay in my case?

interstellar Posted May 27, 2015 Author Report Share Posted May 27, 2015 I rendered my asteroid in Ray Trace mode with shadows enabled on the light source, cast & receive shadows both enabled on the asteroid and with Motion Vector blur enabled. At one point, the asteroid came very close to the camera. All shadows and blurs look great. Quote Link to comment Share on other sites More sharing options...
Tomas Egger Posted May 27, 2015 Report Share Posted May 27, 2015 Ola! Sorry my delay to answer, but if I remember well we improved the motion blur vector code fixing some artifacts problems on EIAS 9.1 ;) Thanks Tom Quote Link to comment Share on other sites More sharing options...
