Hi,
To use the “current camera” you should use the
Clear button to leave it "unassigned" (None) - when empty, the Camera is taken automatically from the render view.
Might be, that your
Back Offset value has to be lowered a bit? It seems to work just fine here and as it's really hard to say, what's happening exactly in your scene just from the provided screenshot, if possible, please feel free to
send us your scene (ideally simplified and containing just this problematic object(s)) to helpdesk@itoosoft.com to check it here. In case of a big file size, please use a web-sharing service like WeTransfer. Ideally, if you'll be able to reproduce it on a minimal scene, which you can send us, it would be great.
Thanks in advance for any further details you can share about it with us / our user community (in case some user(s) will run into similar troubles).
Best regards,
