Magma Gems

With this real-time project, my job was to create the crystal material using Substance Painter and Designer and the Unreal Engine 4. I used Substance Designer to create the base surface textures for use with Unreal's node-based material Blueprints in order to create a parent crystal material with various inputs for changing color, emission, magma crust, etc. to individualize each crystal instance.

Using various noise textures to create a rock-like pattern

Part 2 : Building the texture in Unreal

The entire node tree in Unreal

The BumpOffset node was used to push the interior facets texture deeper in the mesh.

Using the original texture, I masked out areas that would give the appearence of magma "encrusted" on the exterior of the crystal
