Problem inside the UMG editor (anywhere):
A simple UMG animation controls a scalar parameter on a brush material:
In the material , the parameter default is set to 0, which reflects its default state.
As you can see on the brush, which is generated in this form by the editor, It assumes 1 before the animation plays:
Resulting in all my editor previews looking wrong.
Note that this even happens with infinite ranges… The editor just doesn’t update it before any frame plays.
