By vusta · 2015-08-09This is a variant of the the CloneOnVerts but will affect only faces/verts that are facing somewhat down. It is quite rudimentary and due to performance issues with MCG right now...it remains...rudimentary. However, I see this is just a stepping stone for later on...
PS: any beginners out there want to do a little mod ? Find the right node, put a 'Not' in it...and you'll have a system that affects faces that face upwards instead of down...ie. a snow, dust system that falls on top faces....it's quite easy, I've left enough comments in the graph...
