Polygroups Issue

Hi Guys, I am having an issue and it’s really been bugging me lately, Ive attached 2 pics, the first pic shows that i have created a polygroup on my characters lip. No problem there…

However at some point further down the line, and I can’t say exactly when, the polygroups change configuration and the group I selected looks totally different. why is this, and how can I fix it.

Please help.

I’d venture to say you must have changed sub division levels somewhere along the line.

Thanks for your reply, I can safely say I haven’t changed the subdivision at all, I done a quick test, I created my mask, polygrouped it, then I saved the file and opened it up again. Once i open up the file the same issue occurs, the polygroups rearrange themselves.

I found a solution however, or more of a workaround I should say, it was quite simple…

I deleted the lower subdivisions, and voila.

What I’d noticed before was that the issue only happened on a mesh with multiple subdivisions, the polygroup for whatever reason would rearrange itself based on the lowest subdivision level, so by deleting all lower sub’s I forced the mask to stay on the polys that I had assigned a group.

Hopefully this helps someone else who may have experienced this, maybe it’s a bug of some sort, who knows.

It’s not a bug, it’s just how polygroups work. You need to create them on your lowest level if you want them to be consistent across all levels. Files are automatically stored at the lowest level which is why you’re seeing the change.
