Quick Motion Blur

[Infrared digital]

I am looking for a thread that was posted some time ago which explained a way of applying motion blur to VRay renders but, using the scanline renderer and Max's motion blur as a sort of post process.

It was an excellent quick method to get good motion blur.

Can anyone remember this thread ?

Just use the MotionBlur render effect. There is no need to use the scanline renderer.

Thanks for that Vlado.

I have already rendered the animation so, is my only option to do motion blur in post ?

i posted one but that was way back in the days when we were using max3 and vray didnt have its own motion blur. waaay back in the days of the 1st forum.

The one you're thinking of is to make a copy of your scene, set up a material with a camera map per pixel material in the diffuse and choose the camera you rendered from as the camera for the camera map.

Set the self illumination on the material to 100% and apply this material to everything in your scene. This will effectively project your render onto the geometry that made it.

If you now render this scene with motion blur via the scanline the geometry that made the scene will have its colour and lighting from your previous render, but also feed the correct motion blur vectors into the post blur effect to give you the result you need.

I can't use it anyway because I have proxies in the scene and Max doesn't recognise them.
