Hello! I have started trying to use roblox studio more this year and I needed to learn how to become a better builder?
Good question - With building I find it comes with practice, simply try playing games or watching building time lapses. Building is the polar opposite of scripting, you need to unleash your creativity to make something interesting & appealing to the end user.
First try finding your style, see how different people go around building in that specific style, then head into studio & continue tinkering . Consider de-building free models (in a safe environment) you can even try external tools to aid your building career!
