Another example of a roller coaster model generated by Bixelangelo and rendered and exported as a 3D model by BluffTitler: https://www.outerspace-software.com/bixelangelo https://www.outerspace-software.com/blufftitler It features 2 clothoid loops, a cobra roll, a batwing, a corkscrew, a hammerhead turn, a top hat and a dive loop. This one is easier to use in your own projects by attaching your own model to the bot node. It also uses physics and loops perfectly! The license is non-commercial because the bot is the sidekick of our alien mascot Bix: https://www.outerspace-software.com/ After removing the bot, you may use the roller coaster model in your commercial projects.
