Custom shaders bind GLSL and WGSL programs to scene objects via . Uniforms live in typed s, textures are passed as separate resources, and the same shader can target both WebGL and WebGPU. Quick Start Related skills: (built-in filters), (custom geometry), (batch optimization), (shader API migration from v7). Core Patterns Dual-renderer shader (WebGL + WebGPU) If only is provided, the shader works with WebGL only. If only is provided, it works with WebGPU only. The bitmask is set automatically. does not auto-inject . If you write yourself, PixiJS preserves it and treats the shader as GLSL ES 3…
