A course that does not have the information necessary for practical work. 3D work is done in PlayCanvas and then downloaded and connected to React every time? This is an impossible method that cannot be used in practical work. I do not work alone, and UI and 3D objects do not operate separately every time. In the explanation of the connection process, some files are connected in the head and some in the body, but the explanation of such important information is too sloppy, and parts that can be explained in one word or one line are explained too long, making it boring and a waste of time.
