Hi Mike,

Liked your shark tutorial - gave me a chance to use some new tools. I'm in the process of working out a shader. Reference material that I've found seems to be mixed. The shark
seems to have a very hard rough surface that shimmers in direct light. The rest is more diffused, almost velvety like. I thought you might have some experience with sharks and was wondering if you had any ideas on this.

cheers!
