So I decided to create my own shader ball for different kinds of material testing. Next I will be setting up a scene with some basic dome hdri lightning.

Model was created in rhinoceros to have perfect CAD bevels. The size is little over  50cm in all directions. It will also include author info, varying degree of white for adjusting light intensity and  v-rays color sampler,  the floor will have RGB color wheel and a 50x50cm grid.

In the future I will put some of the materials up for download.
