kornel.l.varga Posted April 10, 2014 Share Posted April 10, 2014 Dear all, I am struggling with an issue. Our pipeline s end is based on alembic exports from the animators. They receive VraySubdivision attributes in the mesh, but they cannot pass it on through the alembic export. Any ideas?

chrish Posted May 6, 2014 Share Posted May 6, 2014 I'm not sure what applications you are working with pre/post houdini, so I am not sure if my experience relates to yours. There may be better ways, but this has worked for me. I am exporting alembic from maya. In the export options, I add an entry for an attribute named "vraySubdivEnable". When reading the archive in to houdini (H13) with an Alembic SOP, I remap the "vraySubdivEnable" attribute to"creaseweight". I then promote & recast creaseweight to a vertex float attribute, and remap the values as needed (e.g. fit($CREASEWEIGHT,0,1,10,0)). The results can be displayed with a subdivide SOP, or in mantra with "Render Polygons as Subdivision" on at the object level. I'm not sure if the same can be accomplished with the Alembic SHOP procedural, other than as documented in the "User Properties" section. -Chris Quote Link to comment Share on other sites More sharing options...
