UNR3D's OC, Jade. For most of my journey as a 3D artist, I made cloth details (like wrinkles) exclusively as part of the textures, while the mesh remained smooth or geometrically "perfect." Jade was the project that made me want to level up and start modeling those details. I experimented with a variety of techniques, including cloth physics simulations and manual sculpting, to get natural results. Jade was also a great exercise for understanding bone placement for skirts and being mindful of body movement to prevent as much clipping as possible.
