Particle Parameter colour change not working in viewport or via blueprints.
I am trying to get a simple colour change going for some smoke. I have read the guide on particle parameters, read a lot of other threads and watched some videos. I have followed them step by step but I still cannot get my colour to change through the instance parameters in my particle component. My material has a particle colour.
The colour does change when I change the 'constant' part of the Color Scale Over Life, but that is not much use to me since I cannot access that from the viewport/blueprints.
As you can see from the below images, all the settings should be alright but the colour is still just white...
Any help appreciated.

I know it's really late, but still better than never ^^
I understand thanks to this post
GPU Sprites emitter can't accept Dynamic parameter. And when you expose parameters in your blueprint, it is considered as Dynamic.
But when you put your blueprint in the scene, if you go in Details window, select your particle system, and expose parameters, they are considered as "Static". (I try a parameter for Spawn and it works)
Nevertheless, Color is always considered as Dynamic parameter. (It is not working even in Details window)
Likewise, the blueprint functions setFloatParameter, setVectorParameter, ..., setInstanceParameters, will work on Construct and on Play for all "Static" parameters but not for Color.
