And still I try! But no practical results... I have been trying to recreate that tank-track wheels in one of the background videos, but the stuff doesn´t cooperate! I´ve spent a lot of time trying to figure out some kind of contraption. I´m pretty sure this last one could really work, but the big issue is about the tracks themselves... How did they make a "flexible" track? I tried SO MANY different things... the problem seems to be the same: there is no way to keep the parts together (whatever they are) if you want flexibility. The closer I´ve came was to build a full square track with rotors and their loose parts, and then to close them with a fix built. But, at the time I separate´em from the main vessel, they fall apart. I think they have probably created a bunch of script lines to keep aligning and/or welding the parts together, or even some custom model for it. Oh, doubt! At this point, it looks like some kind of harvester (maybe for Medieval Engineers?) or a mine-cleaner wartank. ............ In the final pictures, the brown rotors are the dull, regular one; the red don´t have heads; and the yellow ones are those which actually work for traction (torque and velocity).
