This mod changes the various creature sizes in the game. Specifically:

Big/Bigger/Huge:
Big version has creatures from small to Huge (but less small than Vanilla NMS) so that bigger creatures are more common,
Bigger version has creatures from Medium to Huge and
Huge version has all huge Creatures.

Unlocked Sizes (As requested):
The Unlocked Sizes version tampers with maximum sizes so that tiny creatures are still possible (Same as Vanilla) but just gives the possibility for some to be Huge. (E.g. Butterflies, Fish, Rodents etc can now be huge.)

Pick the file that you like best. Also currently there is a global limit to how big creatures can get so don’t expect Godzilla sized creatures (Yet)
