shader-fills

By BuilderIO. Updated July 7, 2026. Categories: IDE Plugins.

Code-backed GLSL shader fills and shader effects: authoring WGSL-free, WebGL1 GLSL fragment shaders that persist as readable source in the screen HTML with uniform knobs in the inspector. Use when the user asks for a shader fill or shader effect, sends "Create a custom shader fill." from the fill picker, wants an animated/procedural background (waves, noise, mesh gradients, caustics, grain, halftone), or wants to edit an existing shader's GLSL or uniforms.
