Dearest Future LegendaryCarmine,
For weeks you drove yourself mad trying to figure out why your Unreal export node threw a blank error on every map you made. Plugging in the terrain was fine, but the second you plugged in a mask from a mixer it stopped outputting.
This note is for when you inevitably forget the solution and need to find it again. Make absolutely sure that your mixer nodes have “Preserve Masks” set to true.
Sincerely,
Past LegendaryCarmine
Or come here at set your future self a reminder heh.
