Weird Turbosmooth Results

PredatorGSR

I'm a longtime Maya user who is learning Max and I'm having a strange result when using turbosmooth on a mesh. I'm not sure if this is the normal turbosmooth result, or if there is something wrong with my mesh. Using the Maya mesh smooth would not get this result unless my topology was wrong so I'm a bit confused since everything looks ok to me.

The specific issue is the curved crease at the start of the bend. This happens around all my corners that I make this way and is very visible in the smoothed result. I created the corners using a combination of the bevel and chamfer commands.



Any help would be appreciated.

I'm not sure why the mesh is deforming where it is, but that nasty ngon really, REALLY doesn't help your cause. Make your mesh all quads, then give it a shot!

I agree. Looks to me like it's that 5 sided poly you have near the corner.

5 sided ngons tend to be better than a quad and a tri for smoothing. This is for the high poly bake, so ngons are ok.

Anyway, I figured out that it was something in the edit poly history that was affecting it. I just converted it to an edit mesh, and back to edit poly, and then the turbosmooth worked fine.

glad you found a solution to your problem.

i definitely agree with you that in some cases having ngons in subd modelling is better than using a quad but in the case of your screenshot imo the best solution would be to add an extra edge loop and split that ngon into 2 quads. It looks like you kinda just stopped adding edges ??

there's an extra vertex hidden in there.

select all verts and weld them, you probably have some ngons there, or some vert on a line which you need to remove.

u smoothing by smoothing groups in turbosmooth? That might do it.

select your mesh by verts *before doing turbo smooth* look for the tool stl check and then add it. after that convert to editable what ever your editing in, and it should be fixed. if not you might have a crazy edge and have to delete it and re make it not a big deal but stl check should clear up the problem

Looks like a lot of people didn't notice that I fixed the problem, the fix was converting to edit mesh and back to edit poly to delete some history that was affecting the turbo smooth.

Thanks for the suggestions.
