Closing note and challenge.

Experiment with applying the mat channel parametric, spherical, cylindrical, random, etc...

These settings seem to best work on rounded objects.  Your scene light sources will effect the end results of your material.  IBL lighting will drastically effect the look of these materials.  experiment, experiment , experiment.

The challenge:

Make your own image based mats using this process and post them to this thread.  Good luck and happy Brycing
