I spent too much thinking on what do to this challenge and not doing anything, that I tried to search for other students projects for inspiration. And I found that another student made a tent, so I also tried to make a tent and tried to make a circus tent.
It appears that there’s some sort of a bug in Blender 2.92 (version that I’m using), in which it isn’t rendering the background properly.
It is not a bug. But Blender camera clipping.
Basically, you made the scene too big to fit in the current Blender setup.
I didn’t know about that, that’s why I tought that was some sort of bug. Sorry about that.
Thank you both for your help. I managed to get background as I intended to be.
Good stuff. It was @FedPete who helped.
The camera clipping was just something I came across myself recently.
