3ds max turbosmooth bug/issue?

ghaztehschmexeh

Hey so I think I've run into one of max's lovely quirks. Happily modelling and one object seems to not smooth as expected. I think the last thing I did on it was a slice modifier. There are no double verts. I've tried exporting it and reimporting it. Basically everything gets tighter the more iterations are applied. Almost as if no smoothing was on (it isn't).

Here's the mesh.



Two iterations of turbosmooth



Four iterations



Result after reimporting



Any ideas? I'm probably just being stupid and missing something. Thanks for any help in advance.

Make sure the verts are welded and reset xforms before you export.

Did this already, same thing.

convert to editable mesh then convert back to editable poly... could this be an edge weight issue?

What format are you exporting as?

Just tried converting to editable mesh and back. Checked the edge weights (they were fine). I have tried exporting as fbx and obj. Resetting xform, edge weights, welding all nearby verts, clearing UV map. Now it looks exactly as it would if it was divided without smoothing on...

Edit: ok it turns out that a bunch of faces unwelded themselves, but it still looks like it did before when welded.

can you post your mesh...

I put an edit poly modifier on top of the turbosmooth and it fixed it. Removing it puts it back to how it was though. So that doesn't help.

Ok, adding a turbosmooth with 0 iterations and collapsing it seems to fix it. How bizarre :S thanks for the help guys.

is this what your looking for? SUPER QUICK FIX

This is because obj export freezes the normals, so the easiest way to fix this problem is to but two normals modifiers on to the mesh and collapse the stack.
