MeshSmooth problems.
show user profile  Sangre
Hello good sirs and... probably some ladies.
While working on the side skirt of Chevy Spark I faced this glitch with MeshSmoothing:

The problem appears not because of overlapping vertices or edges as you might think:

After removing these problematic areas the same things appeared in other places.
I've managed to fix the problem after converting the object to editable mesh and then back to editable poly again but I wonder what it was cosed by...

Do you get the same problem with TurboSmooth?

It's weird but sometimes I find that this sort of thing just happens and deleting the faces and then bridging them back seems to fix it.

Weld with a limit of 0.01 with those vertices selected?

Been a while, but that always fixed this problem for me, they just come un-welded.

I forgot to mention that these side skirts are remodeled side skirts of older Chevy Spark that client sent me.
Unfortunately I haven't checked Turbo Smoothing.
It may have something to do with vertex IDs. After removing the faces and rebuilding them these problems appear in other places.
Checking mesh on overlapping vertices is the first thing I did Stephen.
Another weird thing happened today. When I opened the model to check if all parts are in the right places and to give it some finishing touches before sending it to the client I've noticed that the side skirts disappeared somewhere! What the hell?! They are missing in Auto Back files as well. Something strange is going on, something wrong! That's one of the strangest things that happened in my years of modeling.

I don't feel like i know a solution for the problem but what Stephen suggested worked for me with a similar case once. As for the weirdness i've also come at it but my meshes didn't actually disappear but rather became ruined somehow(in terms of topology - just awfully messed up) and i didn't know what to do else but starting every thing from scratch which made me feel very angry. The first thing i'd recommend is to check the names through Object List(hit 'H') if those objects are actually present in the scene(they might have disappeared but still visible in the Select By Name dialog). Once detected try ResetXForm or create a primitive, convert it to Editable Poly, then via the Select By Name dialog attach the disappeared objects to the poly primitive and check if they show up. If it won't help you try to merge all the objects into a new scene, or export your buggy scene into obj or fbx. By the way, personally I've got used to exporting my files into .obj along with saves which ensures retrieving my data if need be.
Some modelers use splines in their models and not convert them into polymeshes until a certain moment and could accidently mark to hide Shapes in the Hide By Category rollout.

Turns out it did not disappear. The symmetry had to be flipped (what a stupid mistake). Anyway I've found this out after I've remodeled the damn thing from scratch >:[
The welding of all vertices with minimal amount didn't help but I remember the problem vanished after converting the non smoothed object to editable mesh and then back to editable poly again. After this there and back conversion the MeshSmooth worked fine so this might help if it happens to some of you guys...

Why do you use MeshSmooth instead of TurobSmooth?

It doesn't make much difference for me since I only use iterations setting which also is in TurboSmooth. The thing is that I've already applied a hot key for MeshSmooth...
