Features

Sliders and Customization

Over 80 different shader parameters, categorized for your convenience. Highlights include:

• Minimum and Maximum World lighting thresholds
• The ability to choose how much pupils dilate in response to baked world lighting
• Refraction
• Two color choices per iris theme
• Placement, size, shape, color, blending, and other parameters for each of four catch lights
• Subtle color blending options when choosing contrasting hues for Feline Familiar
• Midnight Brew viscosity and swirl speed
• Spider Crawl web complexity
• Lunar Cycle speed and offset, as well as the ability to sync the phase initial position and rate to our actual moon! This is the reason for the VRChat SDK dependency.
• A variety of animation weights and speeds

Easy Placement and Rigging

Sphere, Lens, and Planar meshes are provided in a blend file, already UV mapped and ready to go. Is your head stylized? Does it use hollow sockets for the optical illusion? Lens and Planar mesh types offer more flexibility on less realistic models. Don't want to place both eyes individually? That's fine, mirroring the geometry in Blender or Unity will be picked up by the shader, and the opposite iris will be shown on the opposite side.

Anime Style

Scaling the eyes vertically or horizontally won't break the depth effects, so if you don't like to have perfectly circular irises, I've got you covered. Additionally, the Feline Familiar and Spider Crawl styles are impacted by an ombre setting which replicates the kind of gradient common to the anime aesthetic. Lastly, the catch lights have an option to use the iris as an anchor point, instead of using the real reflection angle, to help keep those bubbly wobbly shapes in view.

FAQ

Do I need a license?

Most likely, yes. The only circumstance in which you do not is if you are commissioning an avatar/world from someone that holds the relevant commercial license and you will not receive project files once they are finished, such as with VRChat upload services or avatar clone-on-completion style commissions.

Are there any project dependencies?

VRChat SDK - Base version 3.10.2 or higher

Can I get help installing these?

I don’t offer kitbashing services, so not from me. If you’re a kitbasher or VRChat asset creator and something isn’t acting quite right, I do offer support.

Here’s the gist as far as licensing is concerned:

• If you’re getting in-person help, or help via voice call or screenshare, or remote desktop assistance, then you’re fine with just the license you’re holding.
• If you’re sending files over to someone else to help you, then that someone else needs to hold one of these licenses as well.

Additionally, if you have problems, I have a discord server for support.

Can I use these to promote my content?

Not without getting permission. Reach out!

AI?

I do not use it. I do not want to be associated with it. My work comes from my own imagination, years of self-driven pursuit of graphics programming for game development with the help of stackoverflow and a very expensive education, and the effort of learning enough linear algebra and computer science to achieve what I want to make. Portions of this software come from open source contributions from industry legends. People, similarly passionate about graphics programming, hoping to inspire others. Nothing I ever sell will incorporate generative AI in its production in any way. I do not permit anything I make to be used with or alongside generative AI in any capacity. Doing so is a violation of the license terms.
