Black Hole Eye Shader [VRChat]

Join the Discord to receive news about develop, ask questions, or give feedback ;)

UPDATES LOG:

1. Resolved previous issues that triggered warnings during avatar import with a custom shader. (13.07.2025)
2. Added an improved parallax function: now the eye appears differently not only depending on the viewing direction but also on the camera position. (21.07.2025)
3. Added new render parameters such as ZTest, ZWrite, BlendOp, and more, giving advanced users greater control over the appearance. Introduced a customizable Transparent Edges effect that trims unnecessary material edges (you can see it on my Discord server). Also implemented a function that eliminates unwanted transparency in Cutout mirrors in VRChat. (11.08.2025)

There may be some issues when applying the eye shader to your model if the eye mesh has incorrect UV map. If you know the basics of blender, there is a quick guide on my discord to fix this. There is also a full video tutorial on how to set up an eye mesh in Blender to get eye shaders to work correctly.
