I participated in GMTK 2023 with 23 other developers as 3D Character Modeler, and I also got to do some 3D prop modeling. We used a gradient/color atlas for texturing everything -- the results are awesome!
The characters were created from concept art.
My living room set was an adaptation of another modeler's Cupboard prop so it was matching (Hardev: https://hardev.artstation.com/).
The animator did such a great job making my characters look amazing (MachoBoy: https://www.youtube.com/channel/UCJmXAZVALLqqniXZpxAxf3Q).
