Hi there,

I've had a look around but can't seem to find my answer. I output my render passes from 3dsMax/Vray to a .vrimg and convert it over to an .exr using the command line tool (if anyone knows a faster way I would be interested). The problem is that when I use the Lenscare DoF plugin within nuke I get artefacts around the edge of my test object. They also appear when using the ZBlur node. Any help would be much appreciated.

Thanks

P.S.
The artefacts aren't so clear in the images unless you zoom in.

Instead of rendering to .vrimg, you can just type in .exr and it will render to exr. No need to convert anything.

Are you rendering your depth map to 32bit float? Haven't tried Lenscare in Nuke, but in AE with vray works fine. Also, not sure if you Z depth needs or should be shuffled into the alpha.

Also, can't really zoom in on your images, so its kinda hard to tell whats goin on.
