itai Posted April 24, 2023 Share Posted April 24, 2023 Hey guys! So I have 2 questions, 1) this is an Alembic export from Maya, I need to do some smoke from the tires. Is there a way to hide the control rig's curves? 2) I want to place an emitter between the tire and a road surface, but I don't know how to "get" the position of the wheel. Any tips? Thanks!!

Atom Posted April 24, 2023 Share Posted April 24, 2023 Alembic files typically contain "packed" primitives. This means a single point represents a block of geometry. Try this. Drop a Delete node after the alembic and type the number zero into the group field. Your rig is one of those packed primitives. If it's not point 0, then try typing a 1 into the field. This is a crude way to "solo" objects inside your Alembic. Once you have isolated the point number for the care, change the Delete to non-selected to isolate that car mesh. It may be made up of several points. In the end your delete field might contain several numbers separated by spaces, like 0 3 7 etc... Once you have isolate the meshes, drop down an Unpack node to turn that single point into the actual geometry.
