Maya AbcImport hangs up when loading .abc composed of large triangle geometry data. #166

Closed GoogleCodeExporter closed 8 years ago

GoogleCodeExporter commented 8 years ago
Maya AbcImport seems hang up when loading large geometry data(Confirmed at 
least larger than 7M triangles).

Alembic version: 0.9.3
OS: Scientific Linux 6
Maya: 2012 x64

Procedures to reproduce the issue.

1. Load 7M or more triangle geometry(e.g. Asian dragon from Stanford scanning 
repository) into Maya
2. Export it with AbcExport(This works well)
3. Reset scene
4. AbcImport(CPU utiliziation goes 100%, but no response to Maya)

This is most likely because of MFnMesh::setFaceVertexNormals.  
This is a known issue to Autodesk and we are waiting on a fix.

To verify, you can create a boolean attribute on your mesh named noNormals (and 
set it to true).  This will prevent them from getting written on export, and 
prevent that call on import.

Thank you. It works > noNormals attribute.

But how can we do when we want to export/import facevertex normals?

Actually assigning to Brian since this appears to be done possibly - we can ask 
Monday or next week

Not something we can fix - need provider to fix this. We'll test when fix is 
complete

This should be fixed in the latest Advantage pack for Maya, and might have been 
fixed for some providers even earlier.
