IrisGen - Procedural Iris Geometry Generator for Houdini

IrisGen is a powerful procedural tool for generating highly detailed iris geometry in Houdini. Inspired by the groundbreaking work at WetaFX on Alita: Battle Angel, IrisGen allows artists to craft stunningly realistic or stylized irises with full control over every aspect. Users can generate two distinct iris layers the Anterior Stroma and Posterior Stroma along with precise collagen bundles, allowing for a new level of anatomical accuracy and visual complexity. The tool also provides seamless integration with other 3D software by generating procedural ID maps, making it easy to apply textures and shading across different platforms.

Key Features:

• Procedural Iris Creation: Easily generate complex, realistic, or stylized iris geometry with complete control over shapes, patterns, and details.
• Customizable Parameters: Adjust specific iris features like fibers, crypts, radial furrows, and contraction furrows for endless creative possibilities.
• ID Map Creation: Create precise procedural ID maps for different iris regions, allowing for easy export and texture application in external 3D software.
• High-Resolution Output: Produce detailed geometry and textures, perfect for close-up shots in film, animation, or games.
• Non-Destructive Workflow: Work procedurally, making adjustments without restarting, ensuring flexibili
