Ok it do work changing the Particle system but then i have to make every one of them in color.
So im trying again with the script and get the Parameters from the Emitter/Particle system. And i guss i can use the Set Vector Parameter node to do so?
But nothing happens. It looks like the Screenshot above. And i change the particle system to use Vector Parameters…
The only thing i can think of is that the Parameter name in the Set Vector Parameter is wrong. its Color. But do it has to be more like a path or something?
