Multiple FPS help

I’ve been working on a AAA quality game with my team and there are something’s that we need help on. In the beginning of the game, you can customize the characters face. I was wondering how can you do this without making every possible option. I’ve the crosshair spread every time you shoot depending on how is the gun’s bloom. Is there is a simple and dynamic way of doing this. Finally, I need to know what do I need to make servers for the game. Like what do I need to buy and stuff like that. Pls and thank you.

Question 1 → Customizing face

In the beginning of the game, you can customize the characters face. I was wondering how can you do this without making every possible option.
This isn’t an actual question, I’m not sure how to answer it. Everything in programming requires that you be very specific in what you’re trying to do, and I’m not sure I know how to approach this question.

This shows you the very basics if that's all you're looking for, but if you're going for AAA quality, I'm sure you need something more advanced.

Yes, if you’ve never done something like this, there are LOTS of tutorials available, I would probably check out Virtus on YouTube personally. Like many things in unreal, there are a lot of ways to get it accomplished.

What platform will you be selling your game on? An individual website? Through Epic? On steam?
How much research have you done into server setups already? This is not something that is super hyper critical as early as it seems you are in the process.
You can do a peer to peer setup, or you can do dedicated servers, those are you options, and dedicated servers WILL cost you money.

I always root for the underDogs. You certainly have your work cut out for you. Hopefully these will point you in the right direction?

Thank u very much. This game will be hosted on our website.
