hollow objects fill space possible?

[MrDibbley]

for example would it be possible to have say a bucket shape with open top and several small objects and pack the small object in the free space in the hollow bucket? currently it seems to treat the object as solid and packs around, works great thou, just wondered if it was possible to detect freespace in hollow objects?

Thanks

Yes you just need to add a field for useable space
Any item that doesn't have usable space the usable space field is [0, 0, 0]
