I am making a rocket for an upcoming story game I making. I feel like the size is fine but it seems way too big. The rocket is loosely based on Saturn V. Below are the views from studio and from in-game. In-game it feels much smaller than in studio.
Yeah, it looks like your scale diagram shows the height of the nozzles to be about twice a human’s height.
Your nozzles (hard to tell from the angle though) seem to be about 3 times the Robloxian height.
