I'm just wondering if it's possible to make a server, put some resource in it(sounds, images, etc) and access these resources from a roblox game, because if it's possible, I can use my sounds without paying robux, hence making my game more unique.
Well as long as I've been here I've never heard of this but in a short term as in right now it's not possible, I'm not sure how Synapse X aka : 3dsboy is doing it but it's impressive not gonna lie! It's not possible to upload a sound without paying the robux fee to upload a sound, nor is it possible to get stuff from a game , if you added it to a game that means it's on roblox already.
You can't make sounds without paying robux and without someone moderating it.
