I have a .obj file which has about a hundred layers (with not very good naming convention) is there a way of splitting up the sep layers/groups as files and then reading them back in?

Hey harry, if your layers are coming in on the obj file as groups, you can extract them using a forEach SOP (set to each group as the iterator , then placing a ROP geometry export node inside of your loop (there you may even be able to setup expressions to fix the naming convention)

Bringing them back in will depend in how do you want the data to exist on the scene. Do you want an object per piece, or all of the geometries imported in a single geometry network?

Good thinking I'll try it.
