If i have understood it right custom objects only spawn ABOVE ground. (And as fas as i can tell from some simple test runs it seems to be true)

I'd like to have the possibility to spawn objects which have things below ground level (not just 1 or 2 blocks, more like 30 or so). Cellars for example.

This would help me creating some neat castles etc.

Ofc this is not a high priority but certainly a feature not only i miss.

It's now in. Use SpawnUnderGround:true and SpawnAboveGround:false.

He's working on it.
