I've had requests from customers to have MLI (multi-layer insulation) modeled on spacecraft designs I've done in Solidworks. While the majority of my work is structural, when I am preparing model pictures for a presentation they will sometimes ask for MLI. Problem is it's not just a flat surface but being made of multiple layers of metal ion coated plasic flim (mylar) it has a unique look to it besides being reflective gold. I've tried applying textures but nothing has the large wrinkles that look like MLI. Anyone out there done it and if so can you explain how? Thanks!
