The Scattered Smiles Material was made in Substance Designer.

7 seamless textures 4K, PBR:
- AO

- Base Color (3 texture map)

- Roughness

- Normal

- Height (Displace)

You don't have to use the Height map. Without it, the Normal map works well enough. But with the Height map, you can add more depth and expressiveness. The displasment function is not activated in the Unreal material. Depending on the Unreal version, displasment can be implemented in different ways. Choose the one that suits you best. A height map is included.
