Procedural Eye Generator - Substance Designer Texture
A simple eye generator made in Substance Designer, usable in Substance Painter and .sbsar compatable software.
You can customize the color of the sclera, the amount, shape and color of veins, the size and shape of the pupil, color and texture of the iris. 3 variations of pupil shapes are included, with 4th being an input for a custom alpha texture.
The material is intended for realtime and offline rendering, with two texture layout variations: a single circle, and the sclera and the iris split into different UV islands. The material generates separate roughness and normals for the sclera and the iris, as well as combined texture, with bump offset map and an iris mask for real time rendering.
Pre-generated textures and an eye mesh as seen in screenshots are also provided in a separate archive.
