Client masks like WorldEdit but client.

use /cmask to set/clear a mask

the goal for syntax is to be as similiar to WorldEdit/FAWE as possible. WorldEdit mask wiki

Currently supports <, >, and comma separated blocks. (does not YET support &, ~, !, quotes (""), block ID's, or block states.)

examples:

/cmask stone

will only effect stone blocks

/cmask >stone

will only effect blocks above stone

/cmask <stone

will only effect blocks below stone

/cmask grass_block,>stone

will only effect grass blocks above stone
