Hey prodprod - that's really cool! Been on the Roll-o-Plane many times -- that was like the gateway ride to the Loop-o-plane which went completely upside down lol. We are all still trying to piece together (literally) how to get everything running from Sketchup. I've been using Max, but I want to also go back and see if I can get stuff running from Sketchup. SU exports scenery great, but we're having animation issues. Once we figure things out further, one of us will pass it on! Have you seen any of Svatlas' tutorials on Steam? They sure help with the keyframe animation which can definitely work with this type of ride.
