Hi, all --

I've run into a problem I can't figure out.  I'm using some content from DAZ -- the M3 vest, and it has some strange geometry.  Attached, you can see the "mysterious blue edges" are parts of the geometry that are different somehow.  I can't find in the manual or anywhere else what the blue edges signify.

I am unable to change them.  I'm thinking that they must mean the edges are creased, but I can't smooth them; that option (along with almost every other option when opening this figure in the Vertex modeler) is greyed out.

In a second post I'll put up an image of how this area of the geometry renders using the toon!pro renderer.  It's not something I can use.

I've triangulated the model, and the blue edges stay there, but they don't render with the line, so that's an option, except then the vest no longer conforms to M3.  I've tried taking the newly triangulated geometry into Poser to rig it as a new conforming prop, but get a hundred other creases that show up on render.

I'm at my wits end.  Can someone please tell me what these blue lines siginify?

Can someone offer some potential work-arounds?

This project is an animation, so 'paint it out in post,' while possible, is not practical. 

Please help!

Thanks,
Dex
