I cannot find the direct mapping between the physics engine of 2.1 and 3.5. Hard for me to follow the youtube tutorials

Hi

It's a totally different physics engine, so no direct mapping actually exists. I think you're watching a tutorial that somehow we forgot to remove from youtube... surely it should have been replaced by a new one.

What tutorial are you trying to follow? Could you give me the URL?

Aww... this post got me excited until I realized it was about last version ;)

Haha well, not long to go. We are thinking next week for 3.6... just polishing it up a bit, nearly ready.
