Validate the diagnostic

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

Confirm the reported code matches react-doctor/three-webgpu-no-legacy-material-api. 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

import { WebGPURenderer } from "three/webgpu";
import { ShaderMaterial } from "three";
const renderer = new WebGPURenderer();
const material = new ShaderMaterial({
  fragmentShader: `
    void main() {
      gl_FragColor = vec4(1.0, 0.5, 0.25, 1.0);
    }
  `,
});

Corrected pattern

import {
  MeshBasicNodeMaterial,
  WebGPURenderer,
} from "three/webgpu";
import { color } from "three/tsl";
const renderer = new WebGPURenderer();
const material = new MeshBasicNodeMaterial();
material.colorNode = color(1.0, 0.5, 0.25);

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-webgpu-no-legacy-material-api diagnostic in the current repository. Required change: - Use Three.js node materials and TSL for custom shaders rendered by WebGPURenderer.

Reference transformation:Before:

import { WebGPURenderer } from "three/webgpu";
import { ShaderMaterial } from "three";
const renderer = new WebGPURenderer();
const material = new ShaderMaterial({
  fragmentShader: `
    void main() {
      gl_FragColor = vec4(1.0, 0.5, 0.25, 1.0);
    }
  `,
});

After:

import {
  MeshBasicNodeMaterial,
  WebGPURenderer,
} from "three/webgpu";
import { color } from "three/tsl";
const renderer = new WebGPURenderer();
const material = new MeshBasicNodeMaterial();
material.colorNode = color(1.0, 0.5, 0.25);

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.
