BPR render producing blank images

[Charlie_Hernandez]

Hello, wondering if anyone has run into this before. when doing a BPR I can see my model appears in render passes but when I export it is a blank image. I have tried closing and reopening zbrush with no success.
Any ideas on what this is and how to remedy it?

Thanks.

Might have to see your render settings to know but hope it is the composite pass that is being exported?

Its pretty much default settings with the exception of activating AO and increasing shadow angle thats about it. nothing special
