nParticles and AiRandom
Getting random colors per frame?
Particles have a unique identifier called “nodeHandle”.
- Using aiUserDataInt
- attribute “particleId”
- type : color
- Plug aiUserDataInt into the aiRandom color
- TIP: Using a aiRange to take the Red from the Random and range it.
- Example range Red float 0-1 to 0-7 for things like switch nodes
What this does is takes the particle ID ( Number could be in the millions) and uses that to drive a random number. The aiRandom outputs a Red value of 0-1.
