I d like to animate the opacity of a gauge on my HUD, i set-up a blueprint that does that through Material Collection Parameter, unfortunately the material doesn’t draw at all on the screen. it shows though once i remove the Material Collection Parameter. It also works properly on scene geometry.
I tried couple things with no luck : Draw Material, Draw Material Simple, Set Material to Unlit…
Ps: Anything to do with the “set scalar parameter value” being in Level Blueprint instead of HUD Blueprint ?
Thanks for your help
