For some reason, the Color modules in Cascade have all been changed to use RGB values ranging from 0-1, which means it’s no longer possible to use high values to add glow and emmisive-ness to the particles.
Can this be fixed in the next release, it’s extremely limiting. The only other option now is to use a dynamic parameter or set the brightness in the material, which is very counter intuitive, especially if you want varying degrees of glow for each particle.
Thanks, this is a change introduced in 4.6
