Validate the diagnostic

Confirm the reported code matches this rule before you edit it.

Confirm the reported code matches react-doctor/three-shader-require-uniform-bindings. Compare it with the Before example and verify the same API, framework, and execution context. Treat it as a false positive only when one of those conditions differs.

Compare the code

The corrected pattern shows a focused way to address the diagnostic.

Reported pattern

const material = new ShaderMaterial({
  fragmentShader: `uniform float opacity;`,
  uniforms: {},
});

Corrected pattern

const material = new ShaderMaterial({
  fragmentShader: `uniform float opacity;`,
  uniforms: { opacity: { value: 1 } },
});

How to fix

Use the corrected pattern as a reference. Preserve behavior that the rule does not require you to change.

Copyable fix prompt

Copy this self-contained prompt into your coding agent after you confirm the diagnostic.

Fix every confirmed react-doctor/three-shader-require-uniform-bindings diagnostic in the current repository. Required change: - Add every custom GLSL uniform to the ShaderMaterial uniforms object with a compatible value.

Reference transformation:Before:

const material = new ShaderMaterial({
  fragmentShader: `uniform float opacity;`,
  uniforms: {},
});

After:

const material = new ShaderMaterial({
  fragmentShader: `uniform float opacity;`,
  uniforms: { opacity: { value: 1 } },
});

Constraints: - Confirm the reported code matches the Before pattern. - Make the smallest change that fixes the root cause. - Preserve behavior and interfaces unrelated to this diagnostic. - Reuse existing project components, utilities, and conventions. - Do not introduce render-phase side effects, render-phase state updates, or Hooks rule violations. - Adapt identifiers and framework details instead of copying blindly. - Do not disable the rule or suppress matching code. - Confirm this rule is enabled for the project: three. Verification: - Run focused tests for the changed behavior. - Run React Doctor and confirm this diagnostic no longer appears. - Report the files changed and any checks you could not run.
