3Dcember 2017

For my 3Dcember project, I replicated 12 of my favorite items from The Binding of Isaac (Rebirth + Afterbirth), not including the pedestal rock. I did 3 items per day, over the span of 4 days.

Except for a few simple items, my process for creating every model is as follows: first, sculpt an approximate shape of the item, and then decimate it down to ~1k triangles. Push/Tweak to final shape, then quick UV unwrap and paint. Once the model is textured, duplicate it and extrude by a small amount, invert the normals, and set it to single-side rendering. Assign a black material to that and you get the outline effect. I also made a keyframe animation for the bounce and applied it to every item.

This is all shadelessly lit; lighting is painted directly into the model.

Modeled and animated in Blender, textures painted in Substance Painter with touch-ups in Krita.

Penny wilkerson texture preview

Preview of results of one-button quick UV unwrap: triangles may be very fragmented, but painting them in Substance Painter still gives pretty good results, which is perfect for my needs

Wireframe of all models, showing that almost all of them are decimated sculpts with no quads or good topology. Sculpting and decimating gives quick results, however, and since I'm only doing simple scaling transformations, it works pretty well
