Auto Eye holds a spot in superhive's catalog. It stands out for combining procedural styling across realistic, cartoon and animal eyes with the option to bake Color, Specular, Roughness and Bump maps. A demo video is available.
Auto Eye is a fully procedural eye for Blender that renders in both Cycles and Eevee. Because it relies on procedural textures, the result holds up at any resolution, including close-up cameras. It targets a wide range of looks, from realistic to cartoon and animal eyes.
Customization runs through material parameters and eight shape keys covering iris and pupil forms, alongside controls for the collarette, crypts, fake shadow and cornea mask hardness. Node parameters come in a Full and a Lite version, and Cycles offers a real-time preview.
For animation, you can disable the cornea's viewport visibility on the Cornea Mask modifier to check where a character is looking in Solid mode. Auto Eye can also bake Color, Specular, Roughness and Bump maps, with three tutorials covering the process. It installs as a standard Blender add-on and is added to the scene from the Add menu.
Auto Eye is best for character artists building eyes in Blender across realistic, cartoon and animal styles, using Cycles or Eevee.
Auto Eye is completely free to download and use.
Auto Eye was updated for Blender 4.1x as of version 3.7, a release that also adjusted the Specular Tint and Blindness Roughness parameters. It renders in both Cycles and Eevee. For versions outside that range, or to confirm the latest supported Blender release, check the developer's documentation, since compatibility can change with new updates. The changelog on the developer's page tracks each version alongside the fixes and additions tied to it.
Auto Eye recommends a dedicated graphics card if you plan to use it in Eevee. Eevee leans on GPU power, and because Auto Eye uses quite a few nodes, an onboard graphics card may cause Blender to freeze or crash. In Cycles you also get a real-time preview. If your machine relies on integrated graphics, review the developer's documentation and FAQ for more technical detail before setting up heavier scenes.
Auto Eye installs like a standard Blender add-on. Go to Edit > Preferences > Add-ons and click install, then locate the zip file in the folder where you saved it. Once enabled, Auto Eye appears in the Add menu at the top of the viewport, or through the Shift + A shortcut, listed at the bottom. Click it and the eye is added to your scene at the 3D cursor position.
Auto Eye can bake Color, Specular, Roughness and Bump maps, and its Cornea Mask can be baked as well. Three tutorials walk through the process, covering baking maps, setting up maps, and setting up materials. Because the eye is procedural, the underlying detail holds at unlimited resolution before you bake it out to textures, which is helpful when you want fixed maps rather than the live procedural setup.
Auto Eye is listed as free here. Licensing can change over time, so check the developer's page on superhive for the current pricing and license details. That page also hosts the documentation, FAQ and the full changelog covering each release, from the earlier feature additions through the Blender 4.1x update. Treat the developer's page as the authoritative source for how Auto Eye is distributed today rather than relying on a cached listing.
