T-Spline surface smoothing
@Anonymous
There really isn't an easy tool for this....Under utilities you have make uniform but the rarely works.
one of the best ways to work with T-Splines is to apply a curvature map to the T-Spline so you can fix problems like this and to keep you from creating bad geometry.
I would have to see your model to know the actual problem.

As @PhilProcarioJr it comes down to topology. I would not use any smooth tool here since it is a low res poly body but rather look at the topology and even out the position
of the CVs.
This might be harder to do when in smooth view.
Go to Utilities and inside Display Mode switch between box and smooth.
You can also press CRTL 1 2 and 3
Look here:
All looks smooth and fine:
to sharpen or smooth transitions key is to bring edges closer together or further apart
When however I move the edges beyond the neighbor edge I can start to crease / self intersect the surface too much
based on the image you gave us I think you moved edges too far - just move them back

Hi,
your problem is that this edge ( check picture ) is disturbing the smoothness of your surface, so delete it and you're good
after all it's not about smoothing the surface in sculpt environment, it's about knowing how to manipulate vertices, edges and faces

Not only that but I think the topology is also too dense - simplify it while maintaining the desired shape
and while TS allows it I would advice against NGons

Hi,
Yes you're right, too many faces can cause losing control of the shape being created 🙂

There are times when N-Gons are fine, but this is not one of them. You should confine the use of N-Gons to completely flat surfaces only.

Hi,
What do you guys mean by N-Gons exactly? are you referring to vertices?

@PhilProcarioJr Not necessarily. I should also have been more clear. NGONs in surfaces can work pretty well. However NGONs at surface edges can be disruptive.

More then 4 sided patches.
I still stand by what I said, in over 2000 hours of working with T-splines I have found that you should keep them on flat surfaces only. Using them on any surface with curvature causes you to lose the ability to edit them without trashing your surface. It's just asking for trouble.

A trick that @PhilProcarioJr often used]a when T-Splines go haywire is to export the T-Spline control cage as a .obj and then re-import it converts tinpot a T-Spline.
this may only work, however when you are working with a clear quad mesh, something I would strongly recommend.
if you use n-Gons and t-junctions in your T-Splines it may well back you into a corner. I ma pretty certain two the .obj format does not not support T-Junctions as the .obj format is a lot older than T-Spline technology.
"I ma pretty certain two the .obj format does not not support T-Junctions as the .obj format is a lot older than T-Spline technology."
The .obj file format supports T-Junctions and N-Gons just fine, it's Fusion that can't use them for T-Spline conversion.......

There is no smooth tool in Fusion T-Splines....
In the area of your screenshot just make the faces quads and you will have fixed your model.

@PhilProcarioJr I stand corrected 😉
@Anonymous you should really rough out your shape completely before adding detail to it. One ting to look for is proper edge flow. Watch modeling videos for subdivision Surface modeling e.g. Modo, Blender, 3DS Max, Mays, Cinema D. This will provide you wit a much better idea how to model with T-Splines and is directly applicable!
