Datasmith not working with certain types of materials

using 4.21
Some of my Static Meshes are not showing materials, just shows ue4 checker material
We imported static meshes through datasmith and file import into level and are getting similar bugs
When using a Material with tessellation, and using materials imported from Megascans (material instances
might have to do with some kind of instancing
not sure
Might be a bug or something we’re doing wrong
any help would be great
