ParticleSystemMultiplier class missing a reference

So I imported unity’s standard asset package; character, effects, and environment.

And in the ParticleSceneControls.cs script, it is giving me a CS20246 error. “The type or namespace name ‘type/namespace’ could not be found (are you missing a using directive or an assembly reference?)”

Also before this error occured, the namespace was using UnityStandardAssets.Effects, I maybe (falsely) assumed this was updated to be “ImageEffects.” Because this resolved the broken reference, but gave me the error for the ParticleSystemMultiplier class.

Could anyone shed any light on this error? Or enlighten me to my mistakes?



Just add this to the top of that file…

using UnityStandardAssets.Effects;

I don’t know how they didn’t catch this, or why it’s still not fixed (April, 2016), but that should do the trick. The file is right next to it in that folder.



I have Unity 2019, installed the StandardAssets-Effects and have the same problem - the ParticleSystemMultiplier cannot be found anywhere. Where is it? I even cannot find it in the documentation anymore. Somebody a clue?
