Hey Paul - is there any way to accomplish this in the MODO version? In C4D it looks like you can (for example) solo a noise node going into (for example) bump so you just see that noise output in the Octane viewer. MODO's preview can do something similar. It would be super helpful in everybody's workflow.

Great use of it in this tutorial:
