Hello BABYLON folks!
This is my first post here, and first of all let me thank you for this awesome engine!
I am deeply and truly amazed: Features, Docs, Forum, Community, Youtube channel, Playground, Sandbox, Inspector, Editors for all kinds of stuff. Absolutely mind-blowing. Breathtaking!

After start of my journey back in Mart 1, I finally get stuck. The problem is pretty described in topic title.
here is my solution so far (if it doesn’t render please drag camera a little)

thanks in advance
