I’m trying to import [this skeletal mesh][1] from maya but I keep getting weird deformations in my model when I bring it into Unreal:
Here’s what my model looks like in Maya:
Here are my Maya FBX export settings:
Here are my Unreal import settings:
How can I fix these spiky parts of the mesh on import?
I have confirmed that this behaves the same in a fresh 4.12 project. I’ve linked the fbx file I am trying to import in the original post.
I can also open the fbx in other software without this issue. It appears to be Unreal-specific. Changing this to a bug report.
This usually happens when one or more vertices have no Weights/bones assigned to them. You have to fix this in maya by weightpainting the specific vertices.

Please see the docs . You have missed out a few settings if you might see.
an update you might find this doc useful.

As far as I can tell all of my vertices have weights associated with them. I don’t think Maya even allows you to have vertices that are unweighted, if you “erase” weights from a vertex they get reassigned to another one.
It looks like this tutorial is only for static meshes…
Would you mind listing which settings I missed? I added the import setting to preserve smoothing groups but it didn’t help.
I can check this for you if you want, just link me the fbx somewhere.
It’s linked in the original question, here it is again Google Drive: Sign-in. Thanks!
Please give some time i just now came online let me try it out with your mesh in my pc
Unfortunately I can’t open the original file so I can’t say for sure it’s the weightpaint. exp- and reimporting it from within unreal fixes the mesh, however this breaks the bone rotations
Do you have an older version of Maya / FBX importer? I can either give you my maya project or an export using a different version of the FBX exporter
What are you trying to convert the file to?
Hey there is some problem with your export setting but I tried using the fbx converter and it was not able to convert the file…
Well the file says corrupt and it does not show up so I could not proceed . Let me find you any alternate solution . I am trying to import it in blender then see if the export works…
well the file is corrupt and I am getting an error log.
I ran a cleanup on my mesh and it was altered a bit by it. I’ll let you know if that fixes anything.
A cleanup didn’t fix the issue. I can make the issue go away if I set all vertices weighted fully to my root joint, which makes me think that there is something inherently wrong with the vertices around the thumb on my model.
I’m planning on remodeling this mesh anyways, so I’m probably just going to give up on this for now, and see if it pops up again after I make my new model. If any Epic Games staff wants to know more about my issue let me know.
