BrookerT Posted December 5, 2017 Share Posted December 5, 2017 I've unpacked the geo and converted it, When I try to selected and delete or group the polys I get the error "Attempt to access and object that no longer exists in Houdini" is there a way to delete individual polygons or groups?

Sepu Posted December 5, 2017 Share Posted December 5, 2017 I believe you have to do it before unpacking and converting. Then you will have your groups and whatnot intact. Quote Link to comment Share on other sites More sharing options...
BrookerT Posted December 5, 2017 Author Share Posted December 5, 2017 It won't let me edit individual polygons before unpacking? Quote Link to comment Share on other sites More sharing options...
Sepu Posted December 6, 2017 Share Posted December 6, 2017 Are the groups created in Houdini or somewhere else? Quote Link to comment Share on other sites More sharing options...
BrookerT Posted December 6, 2017 Author Share Posted December 6, 2017 So I've exported an alembic from Maya, and brought it into houdini. I want to edit individual polygons inside the alembic. When I unpack and convert and then try to select the polygons I want to delete I get the error. Quote Link to comment Share on other sites More sharing options...
Jesper Rahlff Posted December 6, 2017 Share Posted December 6, 2017 what are your selection mode based on? if you are deleting polygons based on alembic paths it wont work, since you have unpacked the alembic Quote Link to comment Share on other sites More sharing options...
Sepu Posted December 6, 2017 Share Posted December 6, 2017 can you share your .hip and lock the abc? Quote Link to comment Share on other sites More sharing options...
BrookerT Posted December 6, 2017 Author Share Posted December 6, 2017 so I actually just figured out that if I do the same thing with an alembic exported from houdini, it works. The problem is that my alembic is exported from maya. Does anyone know what setting I'm missing in Maya to get this to work? Thanks Quote Link to comment Share on other sites More sharing options...

Noobini Posted December 6, 2017 Share Posted December 6, 2017 (edited) when exporting from Maya, enable Write Face Sets. Then in H, Alembic, Load As Unpack Alembic.....(or you could also manually add a separate unpack node) Edited December 6, 2017 by Noobini 1 Quote Link to comment Share on other sites More sharing options...

Sepu Posted December 6, 2017 Share Posted December 6, 2017 Those are in the maya export options. Either way if you unpack the alembic you should be able to delete the geo. Quote Link to comment Share on other sites More sharing options...

Sepu Posted December 6, 2017 Share Posted December 6, 2017 you were inside the Alembic archive, just obj merge your geo into a new file obj so you can manipulate the geo. test.hipnc Quote Link to comment Share on other sites More sharing options...
