Skeletal mesh is not visible in mobile preview after updating to UE4.21

I have a humanoid skeletal mesh from 3dsmax that does not render on oculus quest. That same mesh exported directly from Daz DOES show up. I have to run it through 3dsmax to optimize and animate. But coming from 3ds max and I see nothing when ran on oculus. Neither the “Max Bones Influence”, “Percent of Triangles” in Unreal or “Bone Affect Limit” in 3dsmax 2021 appears to have any effect. 2 days in and still no mesh rendering from 3dsmax.
