Lower fidelity art tests/experiments done throughout the last couple of years. Unless specified otherwise these are Marmoset Toolbag renders.
Vertex lighting tests inside Unity, going for something between a PS1 game and early 3D PC games like Quake. Everything uses the same material: unlit, diffuse texture only, vertex color applied on top.
Also in Unity, low fidelity assets with baked lighting, going for something between Half-Life 1 and 2.
Lo-Fi character tests, diffuse texture only.
Unlit material with all lighting built into the diffuse texture.
