I've always had great luck w/ mental rays camera depth frame buffer in combination w/ zblur in nuke.
Now I'm using v-ray's depth render element w/ zblur in nuke and I getting some edging problems. The blur is happening but there is not a nice fall off. Like there is a hard edge then a blur outside the alpha.
Has anyone experienced this? Any tricks with the depth Channel attributes in vray?
Thanks a lot.
