Replacing Model Issues

[selfdestruction13]

I'm tweaking the Eureka mod for personal use and wanted to replace the model of the bobomb buddy to a alien character i found here for a course where's a spaceship.
Was able to put the model and it's custom animation, but now i can't speak with the npc and pass through the model like a ghost, Also whend i move and punch the npc tries to act like i do. After researching a little it said that it might be the name of the skeleton of the model, since it was originally made as a playable character, but i was unable to use blender since it doesn't support bin files.

Does anyone know a better way to make the moddle have a hitbox and able to speak with?
Or if anyone could make that change for me, i would appreciate alot: bobomb_buddy_geo

idk but you should replace bobomb buddy model into alien Character because it have hitbox to talk with npc alien character

you gotta edit the C files for it, so you replace the model spawning with a different E_MODEL instead of the normal bobuddy
