Mesh isn't smooth when i import from maya with Animation

When i import a mesh from maya whit 1 animation the mesh isnt smooth , I can play the animation

Make sure you’re exporting Smoothing Groups from Maya and that your edges are soft (Normals->Soften Edges).

Is this a real geometry or just a smooth mesh preview in Maya? If latter, make sure to convert it to polygons first: Modify->Convert->Smooth Mesh Preview to polygons.

I did that but does’nt work ,i added some pictures the first picture is my mesh
the second are my meshes imported into unreal. the left one is inported whitout bones the right is whit bones and animation.the animation works but not as in a smooth mesh

I did that to , but do i have to do that before i add the smooth skin

No, only after you’ve enabled Smooth Mesh Preview. Do they have the same wireframe and polycount in engine? The static mesh and the animated one.

They you’ re definetely not exporting something. Would you mind posting a screenshot of your .fbx exporter settings?

Have you tried exporting just the Smoothing Groups and Skin first? Uncheck smooth mesh, Bake Animation and BlendShapes. Try it this way.

No the the animated has less

i have the smae reslult no smooth mes

When you are importing skeletal mesh, it has a separate normal import method. I think, by default, importing mesh will have “import normal” as default option, but it might be “compute normal” for importing the skeletal mesh in your case. You can read the difference in the documentation:

[1.3 - Import Normals | Unreal Engine Documentation][1]

I did one just for example

no have the same its like smothing is not importing

its when i put the smooth skin on it doesn’nt inport smooth

i tried some stuff and this is wat have

imported whit: - no reder preview no soft Norm = soft mesh no bone hiërachie
- render preview + soft Norm =soft mesh no bone hiërachie
- render prev +soft Norm +Smootskin = no soft mesh bone hiërachie

I also imported it in unity and have the same result .so i think it has somthing to do whit exporting

Found it i dod not delete my hsitory in maya that was causing the problem .
and inoticed that if you delete history you lose your smooth skin.the one animation workse put lost the weight on it

one more question can i delet history whitout losing the smoothskin

In Maya, you can delete ‘Non-Deformer History’ which should preserve your skin weighting.

I was having the exact same problem - my assets were low poly and not smooth when I imported them in to Unreal. This thread ended a 6 hour search, so thank you! This is what I did:

Delete ‘Non-Deformer History’
Modify->Convert->Smooth Mesh Preview to polygons.
On export choose a preset in the menu - make sure smooth in unticked - this is a bug or something
On import import normals and tangents

Thank you to everyone here, I hope other people will find this thread as well.
