Hi.
I never tried a 4 legged character, but it should be possible.
Even in normal code I think this is quite complex and dependent on your setup.
if you have issues its better to show in a video than sending files, as most people won't download it.
or have a build version on itch.io for example.
Maybe join discord and ask there.
It has 2000+ member and a 400 members average online.
there are also many tutorials on the server.
