@THEOTECH - Unfortunately a screenshot / video upload really doesn’t tell us anything new. We know it renders black. There’s either a problerm with your VRAY install - in which case you could try uninstalling and reinstalling, or, as mentioned earlier, there’s a bad material or VRAY object file path that is causing the problem (which is what happens in my experience). Upload the Model to Dropbox or similar and share in order to further diagnose.
Doe you have any other machines you can test the model/render on?
