Written entirely by AI
The shaders, the settings menus, the build tools, this site and its copy. Nothing was written by hand. You can read the whole conversation at the bottom of this page.
Transparency
Made by AI, start to finish.
Every line of Cornea's shader code, this website and all of its text was written by AI. A person steered it, tested it in game and made the calls. This page says exactly what that means.
Claude Opus 5.5 and Sonnet 5.5
Both ran through Claude Code. In the log below, Opus and Sonnet wrote the replies, and each one is labelled with the model that wrote it.
One person steering
A person set the goals, sent screenshots, tested in game on a Ryzen 5 5500 and an RX 6500 XT, and decided what to keep. The AI can't see the game, so tuning followed that feedback.
Where it comes from
Inspired by Photon. Not Photon.
Cornea chases the warm, soft look of Photon by SixthSurge. Here is how close the two really are, and where the line sits.
AGOAL
Photon was the target
The goal was Photon's mood at a higher frame rate on a modest card. The comparison screenshots on the Features page are Photon, shown only so you can judge for yourself.
BSTUDY
Its source was read as a reference
The AI studied Photon's shader files to learn techniques such as the sky look-up table, the light volume for coloured torches, soft shadows and temporal anti-aliasing. Photon's licence allows examining and learning from its source.
CCODE
The code was written fresh
Cornea's files were written new, with their own structure and many different choices, and no Photon file was copied in. But reading Photon shaped the design, so the two share ideas and some layout. We can't promise no passage ever resembles it.
DSHARING
Only on this site, for now
Cornea is not on Modrinth, because it is AI-generated work. A CurseForge release may come later, but not yet, so this site is the only place to get it.
ESTATUS
Checked, but young
Every program was compile-checked in several setting combinations and the author tested it in game. It is new, so expect rough edges and report what you find.
The receipts
The whole conversation.
From the first message to the request for this page. Only what was said in the chat is shown: tool use is left out, and file paths, local addresses and emails are masked. It reads like a messaging app, but you can't reply.
