Modding

Hello! I need help. I'm making a map where Nicholas is present – he’s the main hero there. I added effects to his body, but a problem arose: how do I make him ride a horse?

Nicholas' skeleton isn't suitable for mounted animations; it would be better to use Nicholas from UHM or create a map with the built-in UHM mod.
