Here’s a neat hack which can help you to emit Thinking Particles from Clones surfaces. The chore of this technique consists of tricking the PMatterwaves node to accept the Cloner Object as a correct polygonal geometry with UV’s by using an arbitrary UV Tag on a Correction Deformer (which can be seen as a polygonal instance). This also works with all Generators so you can easily emit for example from a growing SweepNurb, give it a try :-) (no audio)
