For my client Roblox I needed to make over 350 objects.

Here's a sample of some of the props I made for them. Models range from 300-1200 triangles; all use 256x256 color map only.

The process I used for this was to make a high poly Speed Sculpt (10-20 mins on average) in Zbrush, and use Turtle to generate various bakes to make texturing fast and acurate.

Hats

Robots
For these I provided a quick napkin sketch to show the folks at Roblox what I would make.
