I know! It's an earlier demo version of Machines! It looks a bit... weird, I know. But, it certainly IS that game!
Hmm, the wheels in the release version of the game might have looked a bit like that if they'd used the WL_RM.bmp texture for the tread - I wonder why they went with solid black instead?
The texture for the treads looked a bit odd. Sometimes it's better to hide those details if they don't look realistic enough. Just like mechanical joints in videogames and movies in general.
Maybe this will help (I know, it's not the same thing, but... you know...):
The production process is quite interesting. I would like to implement an organizational structure similar to real companies here. That might help us for setting goals and getting things done :)
