Jagged edges on background after render.

Hey everyone. Having a Zbrush Render issue. Trying to render out a piece and can’t seem to lose the aliasing around the edges of the sculpt. Aliasing is around every BPR render except for the Mask. And the problem only seems to be on the geo against the black background. If I put a plane behind the character the jaggies go away. Obviously, I would like to render without the plane.

Rendering out at 2500 x 1500. Maybe I’m missing a setting or checkbox somewhere?

Thanks in advance.

render>bpr render pass>spix
Is that at a minimum of 3?

Is this only happening on the actual Mask? or also in the viewport when you render?
If you start a whole new zbrush session and just load in a sphere do you get the same results?

Spix is set to 4 in on the main sculpt.

If I initialize and try this on a new project with a sphere the results do change a bit. In the new project the jaggies are gone in the viewport after PBR but the PSD exports still show them. So I guess I can call that an incremental improvement. I should add that my working resolution int the new document is 1435x918.

Also in the original render I’m having problems with the mask is fine. Its all the other maps that have the jaggies.

When you say mask, do you mean the actual “Mask Pass” (a separate black and white image with the default name BPR_Mask.PSD), or just the edge of the regular Shaded Pass (default name BPR_Render.PSD)? Because that default shaded pass tends to keep an aliased edge around the model so that the Mask Pass can cleanly remove it when composited together.

I usually put all rendered passes into a Layer Folder in Photoshop, and add the mask image to the Layer Mask of that Folder.

Yes. I do mean the actual mask pass. OK. From your description this might actually be working fine then. I think I just assumed that Zbrush would be exporting a nice clean model all around. Mask is still handy but didn’t realize I’m expected to use the mask to clean up the edges in this way.

Thanks for the help all.
