is there a way to change the “width” point attribute on a packed object without unpack it?

Anyone ?

I don't think you can change anything on a packed object unless you unpack it. If you control the packing of the object just set the width before you pack. You could also make a scene that unpacks, sets the width then repacks and writes that out as an Alembic or whatever format. Then your main scene can reference the alternate width adjusted version of the packed geometry.

Thanks dude!
