Ancient Chinese Coin - Material Showcase

Here's a simple material made using basic rigid body simulation and a few tweaks that make it tileable and all baked into PBR maps.
I first created the coin itself and dropped a bunch to a floor in Blender and then baked the animation. After that, I duplicated the result and retouched it to make it tileable.
The result was all baked on a plane in Blender with some minor adjustments made in Substance Designer.

Hope y'all enjoy it!

2x Tiled Sphere.

I first sculpted the coin in ZBrush. Always gather references!

Always looking at reference, I quickly textured the coin in Substance Painter. I made two versions of it with slightly different wear/rust.

The rigid body simulation is very simple, it's supposed to be a fairly light object and that's about it. I did increase the "Steps per Second" to increase accuracy and added a thin sensitivity margin to avoid clipping,

I baked the result and duplicated it all around so I could make changes to have it tile properly. It was a fairly effortless process.

Tiling is noticeable but not too shabby given the proper context.
