Bimetallic Singapore Dollar

New series Singapore $1 coin material. I've always wanted to try making a coin pile material after seeing so many inspiring versions on ArtStation. Here's my version using the coin from Singapore. The Merlion and other designs on the front side was a challenge to tackle in Substance Designer; as for the back of the coin featuring the Singapore Coat of Arms, I used a bitmap of the official icon and converted it into a height map in photoshop. Material rendered with Marmoset Toolbag 3.
