@Stefan
sure ...but...
No contact...it's a mysterious coder! :)
You must have twitter for some improbable contacts!) https://twitter.com/ephtracy

The thing the more uncomprehensive is that MineCraft (who has millions of players) has not a decent OBJ to schematic!
it's not the spirit to use something yet built!

And till now you must make that i made!
And it's not entierely perfect because if you use too biggest files (like ZBrush file) you have some luck to have no success!
We are waiting Zarbuz a French coder for that but it's not it's present priority! :)

And i have not yet test the colors of an OBJ to shematic...
Adventure continues...:)

Ps Magicavoxel knows to load OBJ but for the moment only in 126 * 126 * 126 matrix so some decreasing resolution! ;)
Ephtracy will maybe change that when you see these images
