Hi All,

my app generates ply files after scanning objects. After ios 14 update the color of my 3d models does not load correctly. Also I am unable to view ply files in xcode (works fine in preview).

Anyone know the workaround to this problem?
I tired reading ply file content and display vertices and faces in scene geometry but it takes too long to load a file.

Apparently creating mdlAsset() throws some Metal warning and the mesh color does not show up properly.

If the mesh does not have any color vertices the mesh just appears fine.

No solutions found yet. Just to read the ply file and create scene geometry.. which takes lot of time.

What Metal warnings are showing up? We have seen some issues with SceneKit shaders generating Metal warning, but these should not affect rendering.

If you use -[MDLAsset initWithURL:vertexDescriptor:bufferAllocator:preserveTopology:error:] doer error return anything? (vertexDescriptor, bufferAllocator, and preserveTopology, can be nil/NO if you're not specifying them with a another init method)
