on balloongirl "JJ", the bones do not reach the legs and when adding bones, it gives an error

PS: also like BB and JJ, the head is not connected to the spine, but I think it's more petty than the legs

mangle is invisible? at least for me, any way to fix this?

toy bonnies second color/light blue has no ambient occlusion

thats accurate

idk why but balloon boy model is invincible (yes i checked the console. problem is not with the materials)

bone rolls are whacky on some models
