A filter (WIP) that distorts blocks in space in a gravitational way. Configurable material and force strength.
Also added a 'Decay' feature that allows the map maker to cause blotches of corruption on the landscape.
Version 8 adds the ability to 'repel' and 'attract' in the same filter run using the 'Move' option. This is achieved by selecting different block types for each force type.
Have a play...
