This asset contains geometry shaders which, I believe, are not supported on Mac's using Metal.

Poly Planet Creator is a Unity asset that is meant to help create low poly planets. It can be used with 2D or 3D projects. I provide a script for easy mesh manipulation (check the tutorial). The necessary planet data is saved as a scriptable object.

This asset contains custom geometry shaders, designed to work with this asset's spheres. The shaders support Unity's shadow system, multiple terrain coloring modes, liquid rendering, planetary rim, and planetary core effect.

Spheres are generated through a script and are icosahedron-based. They can be generated with up to 128000 triangles.

This asset also contains an in-game color picker which works with the MeshRenderer component or Image component for UI. All color picker elements are drawn with shaders.
