Hi @FattyBull ,
I’m afraid I’m not immediately able to reproduce your problem on Windows or macOS in ZBrush 2022.0.7. Please upgrade if using any other version.
One possibility is that some sort of change you have made in the session accounts for the problem. Restart ZBrush then load the Earthquake file again. Immediately enable AOcclusion in the Render> Render Properties and press the BPR render button at the default settings. If it renders for you successfully as it did for me then it was likely the result of some change you made to the scene or render settings. You could try to retrace your steps to identify it.
If it does not render for you and you are seeing the same problem in all the files you attempt to render with it then your installation or installation environment may be problematic. You would need to contact ZBrush Support for technical assistance.
