lol, I modeled that entire tunnel from scratch and fully intended to populate all five exhibits, but life (work schedule) took that away from us. I used uModeler, and started with a path I drew in Adobe Illustrator. I then used uModeler's "Follow" tool to turn the Illustrator face into a 3D shape. It didn't end up seamless, but pretty close. In hindsight, I should've learned Blender and just done it right. If you go far enough down the wrong way, the tunnel geometry doesn't activate properly, and you'll fall into a collision-free oblivion. If you go the right way, you can take your cheese to the first and only exhibit to get a taste for the vision for the rest of the exhibits. Thanks for playing! :)
