Here's a personal project I've been working on. Wanted to do a stylized skate park. I started by modeling a lot of different pieces with the idea in mind that these would be used for an indoor skate park. Then once I got to a good point I thought it would be smart to start asking how I would make it stylized. I started working on textures as well as figuring out geometry that could be slightly warped.
I did 3 different iterations of a wood plank material with stylized paint strokes to simulate the wood grains. I also did a variant that doesn't have the planks just because I wasn't sure about flat areas and what I'd like those to look like. Very much still being worked on. I plan to work on groups of objects at a time and eventually I'll have a full kit of pieces to arrange however I see fit.
