i was playing around woth the idea to use a 3d-software package to create pixel retro style renderings. I got good results in Houdini. i using SDF volume to scatter point and instance Geometrie on it. this is very flexible. it allows me to use textured character to colorize the “pixels”.
the nice things about it i can use all rigging and modeling stuff, which 3d-software have to offer. is also allows me to use shadow and other shader tricks to create the look. right in opengl viewport, i can design the Retro-design in realtime. i even can mix it up with non-pixlized object, (examples: for the eyes)
check the test renders.
