There is 3d character like either models used in the 3d classic before Frenni, Bonfie, and Chiku, or MMD which has what you would need. Yet I only noticed the MMD versions has Lolbit, FT Chica, and Shadow Bonnie skins bisides the 10 which I know of that have the BB model. There are visual novels that used MMD character models. Now that I recall there is one MMD model that FNIA studios used for William Afton in their novel. There is 4 MMD Bonnie skins(Bonnie, SpringBonnie, Shadowbonnir, and surprisingly Bunzo Bunny), 3 MMD foxy skins(foxy, mangle, lolbit), 2 MMD freddy skins(freddy, goldy), 2 MMD Chica skins(Cica, FT chica), MMD BB, and MMD puppet that I know of.
