Hi,
Thanks for helping me with this issue - I managed to fix it but only after I went back to blender, created a separate label object, [duplicated faces] UV'd it and sent both objects back to 3DC & yes, I did have ignore back faces on in the first try.
Happy to send the original model if anyone wants to work out what the issue was. I've used the vertex lines/curve stroke brush countless times before & never come across this issue before.
Despite the frustration, I've posted a few feature requests for the paint room because, whilst I know most people use 3DC for sculpting, the effortless workflow for texturing in 3DC & sending it back to Blender could be a real game-changer, especially as its easy switching between procedural/smart material & texture painting - something that is really clunky to do in Blender - but 3DC does need a few extra tools. I do have Substance Painter but I tend to use it as a last resort - as in this case, because now the label is a separate object, having roughen the edges of the label means I now need an alpha channel which is not something I've found very easy to do in 3DC
