Hi all,
I export an alembic file with the following command
cmds.AbcExport(j=' -writeUVSets file=“test-uvs.abc”')
This abc file is attached.
and I make sure that the uvset are exported to abc file, this is the abcecho message for this abc file
Object name=/objects:pPlane1/objects:pPlaneShape1
CompoundProperty name=.geom;schema=AbcGeom_PolyMesh_v1
ScalarProperty name=.selfBnds;interpretation=box;datatype=float64_t;arraysize=6;numsamps=1

ArrayProperty name=.vals;interpretation=vector;datatype=float32_t;arraysize=9;numsamps=1
ArrayProperty name=.indices;interpretation=;datatype=uint32_t;arraysize=16;numsamps=1
Then I create alembic node in houdini14.0 and import this abc file
In alembic node, the default value of “Load As” option is “Alembic Delayed Load Primitives”. But if I set “Load As” option to “Load Houdini Geometry” it causes a crash.
Here is the crash log:

My question is:
How to use multi-uv with alembic in houdini?
