No, I always use the latest version of Blender (in this case 2.83).
Yes, all done in one weekend. Keep in mind that the model (the track) isn't that large.
Also, I've used arrays and modifiers to speed up the design, including object instancing to save and share UV space.
I began to create just
one platform, but I eventually created 3 and made bridges between them.
Build up some fences, baking AO and Diffuse maps, paint work in Substance done in few hours.
Also I have project files for animated water, so I can adjust some settings and render those out easily.
Now, I'm busy with some custom animation, which take a bit more time, so I''m trying to finish those.
Then only some .taz, .pan, and .fan files to be made..
