Attribute transfer ‘Alembic Path’ issue

Recommended Posts

I have this object made in 3ds Max that has maybe 10 different parts, which in Houdini show up as 'Alembic Paths'. After voxeling the object i need to restore the information of these 'parts', but when in attribute transfer i select 'path' from the dropdown, i get messed up results. This is how it looks before Attribute Transfer ( and this is how it looks afterwards. What should i look at to resolve this?

Hi,

it seems like you use for-each loop Peace Elements - Points, hard to say without the scene. Use for-each named primitive loop and set Piece Attribute - 'path', it should work without connectivity sop/

to recreate a path attribute you need to work each piece in for each loop (for each named primitive) or else things get mixed up as you can see. so, voxelize each "path" piece separately and then (still inside loop) copy over the path attribute from the geometry before it has been voxelized. don't use attribute transfer as that is proximity based. use attribute copy that works on element number basis. normally this wouldn't work but sice the path attribute it just one value per any currently processed piece it does not make any difference.
