I started seeing these artifacts on my skeletal mesh. I have no idea what is causing it. I returned to Maya and redid my UVs, hoping it would fix the problem, but it didn’t.
When the camera is in motion, they appear like black squares around the mesh.
Thanks
Greetings @raptoreagle
Which Unreal version are you running and have you toyed with the AA and AO settings to see if it’s being affected by that?
I’m using 5.5.3
I’ll try them and see what happens.
Thanks
No problem! Let me know if you still run into issues.
How are you exporting from Maya? I’ve ran into issues before with trying to export models with smooth preview as FBX. I found it was better to bake the smooth down in Maya first, then export.
Also exporting as USD has worked much better for me, as it is much much faster than exporting FBX for something like a CAD vehicle model.
If you do export as USD, make sure to set Subdivision Method to ‘None’, otherwise the file translation into Unreal will shatter normals, edges, etc.
When importing USD into Unreal, uncheck all options under ‘Kinds to collapse’ otherwise the model will be combined into one mesh/actor. Also set Nanite Triangle Threshold to a very high number like 100,000,000, otherwise Unreal will convert any mesh over that tri-count to a Nanite mesh, which I have found breaks the meshes entirely.
