MaterialBillboard Base Size x and y can be set per Blueprint but don't work. Help!

[vangel76]

I’m setting it animated with a “Set members in MaterialSpriteElemen” per Blueprint, but it doesn’t change at runtime.
MaterialBillboard is Component of an empty Actor-Node.

What to do or BUG???

I realize this is an old topic, but just in case anyone stumbles upon this: it does work, however you need to re-apply the modified MaterialSpriteElement to the billboard.
