No worries, just to be clear the material just needs to be made transparent. Nothing fancy required haha.
Also wanted to say good job on the game, I read your 'my first game jam' devlog where you wrote down the process of what you did each day. I think it's very cool what you did and also documenting your process like that. It was fun to read it and gave me some laughs (I see you enjoy fixing bugs eh? I should invite you to fix mine! :D). Regardless, detailing how you did the day night cycle, and using the animator event to change the skybox is very creative by the way! :)
