Particle Instance Parameter color update not working

I try to set the color of a particle via instance param in blueprint editor, but it does not update.
Here is particle param - default yellow

Here is instance - set value to red, but color remains yellow. ???

Here is material

I think this is a refresh bug/glitch. I added a new instance of the BP and viola! - it’s working.
So the workaround is to refresh/add new instance.
Although - it feels broken. BP editor never updates either.

This happens if you use the “Expose parameter” button, it’s bugged and doesn’t seem to add the instance params to the component properly under the hood.

If you add the instance parameter to the array manually, it updates fine… it’s just a bit annoying since you have to look up all your parameter names and it’s prone to human error that way.

thanks Spoondog.i will try that when i get back to that part.
