But if I do a finished render I get this................

This has been going on for awhile on other models.
Any known way to fix this?
I stopped doing bump maps altogether because of this.

V15?

yes

Try rendering using multipass on (try 2-3 passes to test) - I suspect you have multipass off?

There has been a known problem with surfaces that have both bump maps and a material and rendering multipass off.

Or similarly - If the hand also has a material on it - try temporarily deleting the material and rendering with multipass off

This may be the problem or not - would need more detail

multipass was off, so problem solved!
Thanks!
although rendertimes just climbed lol

You should probably get rid of all those empty rotoscope containers, not that it will affect your bump map. It is possible that every asset in your project now has them, so just deleting them from the chor may not get rid of them permanently. In past AM versions, I have had to open each asset, including materials, in a text editor and search/replace all empty rotoscope tags.

Thanks!
but the bassist kinda bailed on the project so this might be wasted effort now.
