Hi there - I am rendering a scene with motion blur and comping in after effects. The AOVs render without the motion blur applied, so when I come to comp the scene using the depth pass for example, there are hard edges everywhere that should be blurred.
How do people tend to deal with this issue?
Hi
I see motion blur in AOVs like direct, diffuse, specular, P, N, and Z when I render to picture viewer.
Hi Stephen,
Thank you for your reply. Looking at the Z pass more closely, it looks like there is some kind of motion blur going on, but the edges have a completely different quality than the beauty pass...
I think maybe because the Z AOV is aliased, it looks dithered and much sharper which is why it is causing issues in compositing.
Is there something I am missing? Is the general practice to render and comp without motion blur and then add it in post via motion vectors?
Check out this thread:
It shows you how to make the Z pass anti-aliased by changing the filter type to gaussian.
Thanks Peter, that has fixed it. I have replaced the Z pass and my comps instantly look correct!
It might be worth considering having Z as anti-aliased by default, personally I cannot think of a use that would require it to be aliased.
