I'm learning to use Vray through Grant Warwick's course "Mastering Vray". In the process I created a transparent plastic tarp material. This scene was built around that tarp geometry. In the process I had to learn Marvelous Designer for cloth simulations, 3D Coat for retopology, UV Layout which all started with 3D Studio Max! CRAZY!
Now this is just a WIP, and a materials study, but I'm having lots of fun while I'm at it! Learning new programs is a blast.
