nParticles ageNormalized


#1

Ok, so I’m having a bit of a problem. I can’t seem to get the particles normalized age working. I have used this previously without an issue, but I’m now getting the error “Attribute not found or variable missing ‘$’: ageNormalized”

I have the particle lifespan on random range, so it should have a normailized age.

The expression I’m trying to create is:
goalU=1-linstep(0,1,ageNormalized);
goalV+=0.15*(1-linstep(0,1,goalU));

Any ideas?
