Hello,
Using the Lyra starter Project, I’m trying to customize some of the UI materials that come with the game and i’m having troubles with the selection of curves from the UI materials.

  1. If I open the parameters for:
    Game/Content/UI/Hud/Art/M_UI_Base_AmmoCounter.uasset

  2. in the parameters->Globals i try to change “CA_Glow” so i follow to the content location, i duplicate
    Game/Content/UI/Hud/Art/C_UI_AmmoCounter.uasset let’s say i rename the duplicate to C_UI_2AmmoCounter

  3. Going back to M_UI_Base_AmmoCounter i cannot select the duplicated curve.

  4. I also cannot select a curve created using the +Add → Curve → LinearColor

In the end i can only select the curves that are in the original Game/Content/UI/Hud/Art folder. Anything else, duplicated or new, even in the same directory is not detected. Regardless of restarts of sort.
I’d guess it’s some kind of filetype or fileversion incompatibility that is not correctly duplicated with the “Duplicate” command?

What I missed is that there is a CurveAtlas that contains the set of curves available to the material. So the material will only access the curves available in its Atlas, i had to add the new/duped curve to the atlas for it to become accessible.
