Not as interesting as my valley collection, not even nearly.
Though, It all started in canyon for me, the mesh modeller was recently introduced and I took a first dive quite fast. Back then there was very little or no tutorials nor decent documentation so happily I went with try-and-fail-and-try-again, teaching myself how it could work. I quickly moved more into Valley after learning basics so my canyon creations are bit so-so compared to the green environment :)
...Luckily times have changed and now more and more people are picking the tool up and succeeding at making brilliant customizations.
I tried to avoid some heavy overlapping with other player creations. some blocks might bring small joy. I see no reason to post every simple item piece that can be easily made by even a beginner mapper/modeller. You'll find some older experimental pieces from this. Also no one-time-used -pieces here, some template roads might be for modellers
