HyperIris
The HyperIris plugin
Point it at the folder that holds your packs, pick an iris, and press Build Iris. It sets up the blend shapes, groups the meshes, and creates and assigns the HyperIris_Surface Arnold material with every map already linked.

Browse your iris library and build the irises, with or without blend shapes.
Set the iris color, from the built in presets or create your own, and the SSS density of the iris shader.
Rigging tools for the eye, like attaching each iris to the sclera.
Drive the pupil with pupil life and light reactive settings.
One price per pack
Pick your license on each pack's page before adding it to the cart.
Questions
Do I need Maya to use the packs?
No. The packs are OBJ meshes and EXR maps, so they open in any 3D app. The free plugin is optional and sets everything up in Maya with Arnold in one click.
What is in a pack?
A matched left and right iris: neutral, dilated and constricted highpoly meshes per side, a lowpoly version, and 3 EXR id maps per side at 4096 × 4096 px.
Which license do I need?
Personal for learning and portfolio work, Commercial for client and paid work, and Studio for teams of up to 10 seats on large productions.
Is the plugin really free?
Yes. Add it to your cart at no cost, or check out with just the plugin to download it right away.
How do I get the files?
Checkout is handled securely by Paddle. Your downloads appear as soon as payment goes through and stay available for 48 hours. Save them somewhere safe; if you need them again later, email us with your receipt. Your license is included with every download.
Can I get a refund?
Because the packs are digital files, we can't refund them once they've been downloaded. If you haven't downloaded yet, or a pack is broken or isn't what was described, email us within 14 days of your purchase and we'll make it right. The full policy is on the Refunds page, linked at the bottom of every page.
