Maybe I misunderstood what the option meant but I tried disabling the limit character proportions options but it doesn't seem to do anything. I'm still constrained to the same body sliders with the same limits for my characters.
quite funny, but they should just upgrade some things like horns, tail and ears size changes, as theyre literally just assets, and how will you change the size? just split the horns and set some points, and make sure the inner circle just fits in the head
