I am a relative new Poser user using Poser 10. When I load the harness figure it behaves entirely as expected. When I change the skinning method to Poser Unimesh and adjust the subdivision to 1 or 2 to improve the render quality, I get rogue vertices as shown in the image provided. I have experiment with other items and encountered the same issue. I have no idea what the issue is because it occurs even with the item in the zero pose. All the vertices seem to belong to a group and I cannot imagine there being an issue with spherical falloff because the problem exists without posing. Any assistance would be appreciated. Be gentle though - I did mention being new. Thanks.

I'll move this to the Poser forum where you're more likely to get ananswer.

I had that happen to me once or twice. Try changing the preview mode and see if they disappear. Or is this happening in your renders?

I'm guessing (just a guess) that these rogue vertices are left over from improper modelling. You'll have to open it (the item's .obj file) in a modelling program like Blender and delete them. They may be there for a legitimate reason but I can't see what it would be.

Thanks for commenting. They appear in preview and in renders - but only after i change the skinning mode and increase the subdivision level. It's like they aren't grouped, but I would have thought increasing subdivision would leave all the vertices grouped. unless I resave the item after subdivision - it would not have a new .obj file?? This might indicate I don't understand the spirit of increasing the subdivision level. I was imagining it as something I did when close to being done - ie after all the test renders etc. I didn't imagine it as a way to improve the basic figure and resave it the library with a new .obj file.

What you are seeing is the fact that the geometry was not made with Subdivision in mind and the SubD algorithm puts some of the points at 0,0,0. No matter where you position the geometry, it will end up with spikes going to that point. You can sometimes get around this by subdividing per body part, other times you have to use another method such as Snarlie's Subdivider Script, another 3D app, etc.

In the end, something in the geometry of the harness is made incorrectly for use with that version of Subdivision. Which is one of the downfalls of version 2 of the algorithm.

Poser 10 uses version 2 of the SubD algorithm, Which as you discovered doesn't always work out as planned on all meshes.

Poser 11 uses version 3 which is far more forgiving when it comes to meshes not being correctly made for Subdivision version 2. You wont get those spikes in P11. I am fairly certain that Version 3 of SubD came out after Poser 10, But it is in Poser 11.
