A simple material ball model to test and display your Blender materials. I did remove my logo from the model.
Lighting setup in the scene is an altered version Studio Setup 2.0 - Cycles by RegusMartin whose original .blend file can be found here: http://www.blendswap.com/blends/view/74897
Looks great. When you remove the ball itself and rotate the inner part around Z, it also makes a great rotating pedestal/podium for your (hero-) characters.
This is so useful! Thanks for uploading.
