Dynamic Material Instance Parameter not applied on Play.
In my blueprint construction script, I'm creating a dynamic material instance from my particle system. The particle system only has a single emitter, so index 0 is used. I have a material expression scalar parameter exposed from the material that I'm editing via BP.
This works as expected in the editor. Changing the Emissive parameter modifies the material. However, when I hit play, the value set via BP is not applied to the material. While playing, I can select the BP and see that it still contains the correct Emissive value and if I modify this value it will suddenly kick in and work.
