I love blender. However what puts me on hold is complex work a rounds to get reflections to work.
I wish there was a one click button to make a object a mirror 
Great tutorial. I will play around with this for my project.
Really liked the tutorial, I’ll be sure to use it again 
But that’s actually a pretty tall order, I don’t think there’s any game engine out there that makes it that easy - but I can definitely relate to the sentiment.
Of the reasons why I actually prefer the BGE over other engines, the level of control granted to the user, is perhaps the most important.
