Ray Kiln for Mac

The app the episodes are made with: write a shader, see it run as you type, move its sliders, record it, and share it to the gallery.

What it does

• An editor with the shader running beside it, recompiled as you type, errors shown on their lines.
• Start from any episode: the app copies it into your Documents folder for you to change.
• Sliders for every // @param line, with presets you can save.
• Stills and video, the same exporter that makes the episodes' videos.
• Share to the gallery: the app records an eight-second loop and uploads it with the source.

Opening shaders from the site

“Open in Ray Kiln” on an episode or a shared shader hands its source to the app. The app shows you the code first and runs nothing until you press Run.
