As you can see, the Fire Sprites don’t change their Colour, although the Material is set to use the Particle Colour.
The Particle Colour works without Parameters and the Constant Value of the Parameter is always taken.
Do you have initial. Color and color over life? Disable color over life.
Doesnt work.
Edit: Got it!
Initial Colour doesn’t work as a parameter!
Use Color Over Life as a parameter!
I use Initial color as a parameter, no problems on my side.
If you did use color over life, it overrides the initial color from the moment of birth. Instead use scale color/life.
