FUN FACTS!
I've been experimenting for
my still-experimental mod, and found some neat things... Skeletons and flesh and all that junk are caste-moddable. Just copy-paste all that standard dwarf body stuff into the caste sections (that means it's there for both males and females), and subsequent castes can have whatever wacky body shape you can impliment. (When I tried to breed giant cave spiders and dwarves, then mate their offspring with serpentmen and minotaurs, they called me MAD! Well, who's got a mutant army NOW?! BWAAAHAHAHA!)
Incidentally, it's a BAD idea to try to leave the regular body stuff back in the "all castes" section, then put in the different skeleton on a specific caste, thinking that the skeleton in the caste level will override the "all castes" skeleton, which would only behave as a default.
I wound up with several "normal" dwarves, and then, when I had my serpentine dwarves, they had several pages of additional limbs.
Quite humorously, there is a second "upper body", which has two heads and two lower bodies (including the ones already on the body normally)...
All told, it tallies up to 3 heads, 2 upper bodies, 3 lower bodies, 6 upper arms, 8 lower arms (yes, more lower arms than upper arms, I guess they split at the elbow, or something), 10 hands, and 3 tails... Somehow, all I can imagine is an image of Vishnu or something.
