How do you properly import rigs into studio?

DISLAIMER: I HAVE NO IDEA HOW TO USE BLENDER. I have looked at tutorials on how to import rigs but i’m still really confused. Please be patient with me

So i was importing some placeholder models from another game (an unreal engine game, not sure how bad that affects it) and i cannot rig it properly

So after exporting as fbx i realized that it doesn’t port the colors over, so i export as glb which splits meshes based on color which worked! until i rigged it with roblox’s avatar setup (only way i know how to rig it since it worked alright-ish)

it did this


(had to dissect the arm)

can anyone help me with this i feel like i’m going insane
