Alembic file with multi uvset cause crash
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[6];arraysize=6;numsamps=1
    ArrayProperty name=P;interpretation=point;datatype=float32_t[3];arraysize=9;numsamps=1
    ArrayProperty name=.faceIndices;interpretation=;datatype=int32_t;arraysize=16;numsamps=1
    ArrayProperty name=.faceCounts;interpretation=;datatype=int32_t;arraysize=4;numsamps=1
    CompoundProperty name=uv;schema=
      ArrayProperty name=.vals;interpretation=vector;datatype=float32_t[2];arraysize=9;numsamps=1
      ArrayProperty name=.indices;interpretation=;datatype=uint32_t;arraysize=16;numsamps=1
    ArrayProperty name=N;interpretation=normal;datatype=float32_t[3];arraysize=16;numsamps=1
    CompoundProperty name=.arbGeomParams;schema=
      CompoundProperty name=map1;schema=
        ArrayProperty name=.vals;interpretation=vector;datatype=float32_t[2];arraysize=9;numsamps=1
        ArrayProperty name=.indices;interpretation=;datatype=uint32_t;arraysize=16;numsamps=1
      CompoundProperty name=uvSet2;schema=
        ArrayProperty name=.vals;interpretation=vector;datatype=float32_t[2];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?

Cheers

No crash on OsX, H14.0.474.  

 

Can you try the UnpackSOP instead of "Load Houdini Geometry"

[TheDude]

worked great for me 14.0.292 kubuntu 12.04, seems like you gotta unpack after delayed load alembic though -- no crashing either way
