I like your asset pack =)
Wow, that is a truly awesome and unique way of using them! I have a small fix coming shortly that will fix the issues with the faces on that "bucket" , but this is awesome and giving me new ideas to work with!
Thank you for your work! I'll enjoy a proper bucket! And maybe a steel wheel for the tracked stuff.
I have rollers in the works, it's just a royal pain to line them up semi-properly with the tracks.
