I had been trying to make
@TheEmu's Tunnel-A, to perform sharp turns left or right
but with little success. I had to resort to starting the scene with an offset vanishing point
and animating it on the x axis via 3D camera. Also used Totem's clouds.fsh as a background.
When converting any scene from 2D camera to 3D camera, it is best to note the difference in default texture hotspot settings that exists between 2D & 3D camera .scns. Hotspots are the first parameters I usually
// rem out when converting 2D sprite nodes for a 3D cam.
