I got the plane I made in Blender into my favourite game engine / game. This is a part of why I am learning Blender, to create assets for that engine. The game engine calculates physics including my character colliding with the plane which made it a more realistic experience.
I couldn’t hold back but view the teacher’s solution before creating my plane. That’s why it looks almost identical, but I was able to create it on my own after having watched it.
