I understand your point, but since the idea is to stack a bunch of diferent modifications on top of eachother they always rely on point position. So I am always doing something like self.pointposition + x,y,z... therefore cumulating values. Thinking harder about it, if I relied on emit location instead of point position, that might work...
Having two clouds sounds like it could really work. Will try that. I did a quick test using post-sim Fabricio. I felt like it had limitaions, but since I am not in front of Si right now I cant really describe it. Thanks for all the good insights guys, ill do some tests and post back with the pros and cons of each approach.
