Hello,
I’m going to be rendering out an animation that I’m completing for university and I’m planning on rendering out passes such as ZDepth and Velocity for adding depth of field and motion blur in the compositing stage.
The problem is that one of the character’s in my animation will have hair which I’m going to do with the Hair & Fur modifier, but the only way that you can get the effect to render out in the ZDepth and Velocity GBuffer channels is to render it as geometry (as far as I know), but then you lose the nice light scattering material which you get when the hairs are rendered using the buffer or mr prim methods.
So the question I’d like to ask is if anyone knows how to create a material using mental ray which resembles the default Hair & Fur material which you get when the buffer or mr prim methods are active?
I know that you can get motion blur when using the buffer effect by applying a Motion Blur effect in the Environment and Effects window, but then the hairs don’t appear in the ZDepth channel. Conversely, if you use the mr pim method then the hairs do appear in the ZDepth channel, but not in the Velocity and applying the Motion Blur effect doesn’t work.
Any help would be welcome most welcome.
Thanks,
-Harry
