Done in Blender. No texture painting or images. All shaders and incredibly simple shapes.
There's a little After Effects for vignette, lens dirt and colour correction (Which probably could have been done in Blender too).

Cheese World

used blender to model a skeleton low poly, then made a forest and some other stuff like grass and such, then pixelized it by changing the render ratio to really low and making sure the render used on linear or cubic (cant quite remember this step been a few months), then went to gimp and mucked about with hue and value until I got some fun colors and then used some blend modes to finalize some of it

you can smooth out the print lines just by printing in pieces and at certain angles, after that, prime and you're good
