Can't get frost to appear on HUD
We're trying to get frost to fade in and our on the HUD at certain points during the game.
We've applied it as a material to our hud widget like so:
The material in question looks like this:
Every frame, we set the value of the material collection parameter, which you can see in the lower-left of the material above. Here's a screenshot of the one and only place where this collection param ever gets set, with a value very close to 1, which is at the point where we should be seeing frost on the screen, but are not:
Here's the odd part: if we replace that "Collection Param" node in the lower-left of the material with a constant "1.0", suddenly we see frost on the screen in-game exactly as we should.
So, what are we doing wrong? Is it a bug in the material, or is the frost simply not updating due to being on a UMG widget for some reason? I'd hoped setting "IsVolatile" on that widget might fix it, but no such luck.

This turns out to be because UMG doesn't support material collections yet.
We've worked around the issue for now, but I'm hopeful this will get fixed.
