Haven't had a blast this past weekend, pun intended. Hit a snag in a network that was working before.
In a simple FLIP tank sim I have some geometry (the letters HELLO) than I am trying to delete inside my DOP network.
Simply using a Group type of ‘Primtives’ with Group wildcard ‘*’. Toggling 'Delete Non Selected seems to work in that my particles are deleted. But when untoggled my geometry should be gone.
