Other platforms were not testedTextures20 demo textures: 19 at 16x16 to 64x64 px, 1 at 4x128 px (PNG, generated by code)PackageAbout 300 KB (.unitypackage), single root folder Assets/REEBOO/RetroPsxFxAI tool used: Claude (Anthropic), through Claude Code, as a coding assistant.What was made with it: the C# scripts (runtime, editor tools, demo), the HLSL shaders, the code that generates the demo scene (meshes, materials and textures), the HTML manual and the store text.What our team did beyond the generated output: specified the features and presets, reviewed and edited the code, and tested it in Unity 6000.3.26f1 / URP 17.3: compile checks (0 errors, 0 shader errors or warnings), clean imports into new projects (Forward and Forward+), automated smoke tests that render 10 presets, material converter tests with Undo/Redo, a Windows D3D12 benchmark and a WebGL2 run in Chrome. Bugs found in testing were fixed (material converter emission detection, two shader warnings in WebGL, moire from masks and scanlines, over-bright presets, fog). Presets were tuned by reviewing renders, and a near-duplicate preset was removed.No AI image, texture, model or audio generation was used. All textures are generated by code, and all screenshots and marketing images are renders of the demo scene made with the package's own shaders.
