Hey thanks, that makes sense. I just couldnt figure that out. Knowing the emitter keeps calculating old particles I now know to keep any future particles in small quantities and short lived to shorten the render times. I assume using “Die on impact” also would also shorten the lives of old particles as well. Unless it only works when collisions are enabled.
Yes, I already discovered the “No calculations in 3d” box. That was a big day.
I appreciate the help.
Im a longtime user (have a Ray Dream manual on my shelf), but I guess I should check out this forum more often.
