The mesh seems to not be upload properly. I tried with different meshes, closed ones, with different file sizes, but couldn’t find the reason of why the mesh is upload as in the pic. I send you also an screenshot on how I applied the UploadGeometry command from Shapediver.
The BUNNY2 mesh contains lot of n-gons and the Geometry Input component supports only quads or triangles. Please follow the steps below to fix the mesh and let me know if you struggle.
