When I try to extract the alpha from another block, I close the bundle, look in it again, and the block I set it for dissapears, and it does not work. @grazer?
that happened to me once
Im assuming you picked a specific object?
If it still does this after selecting the type AND name of the object, then you need change the name of that object your trying to extract from.
Thanks! @JR01! But I just used the global behavior.
