Urm, hi. I am creating a game got Era Of Freedom and I have alot of things in mind for it, one of the things weapons, I have made a custom weapon, but right now I am using the roblox official sword model to test somethings out. I just can't get my custom character to hold on to weapons, this really slows my progress. If you want me to make a quick video as to what is going on I will gladly make one and link it, I really need to understand what the problem is, so in the future I will know how to fix it. Thank you very much, any help is greatly appreciated.
Try Welding the weapons to the player model. I'm unfamiliar with using custom character models, but I'll assume they don't support normal roblox functions such as the backpack. You'll have to use your own custom welds to get swords to stick to the player.
