Changing the shader across the life of a particle?

Robert_Bobbinson

I have a CPUParticles particle system, and I want it to look like fire. I want to change the color of the particles across their lifetime so they start a whiteish orange, pass through a red fase, and end up being somoke. Is there a way to make them change color? Is there a better way to achieve a fire effect?

Use TIME Maybe also LIFETIME or uniform float current_age

Maybe you should do something like this

uniform float current_age;
void vertex(){
	if(current_age < BABY){
		// whiteish orange color
	else if(current_age < ADULT){
		// red color
	}else{
		// gray color and spare vertex
	}
}
