make it possible to save the blocks of other mods intro a blueprint

@SpaceToad can you assign this to me?

This is already possible. "Simple" blocks of other mods are natively supported. More complex blocks will require custom development from the mod authors, which is why an API is provided (SchematicBlock and SchematicTile in particular).

So unless I misunderstood, there's nothing specific to do here.

sorry, then i missunderstood what you said on the forum
