Save the current WorldEdit region using the Minetest Schematic format to "(world folder)/schems/<file>.mts".

//mtschemcreate some random filename

### //mtschemplace <file>

Load nodes from "(world folder)/schems/<file>.mts" with position 1 of the current WorldEdit region as the origin.

### //mtschemprob start/finish/get

After using //mtschemprob start all nodes punched will bring up a text field where a probablity can be entered.
This mode can be left with //mtschemprob finish. //mtschemprob get will display the probabilities saved for the nodes.
