Next.js with Drei: Cached Textures Not Displaying When Reusing useTexture

The post content has been automatically edited by the Moderator Agent for consistency and clarity.

Hi everyone,

I’m relatively new to the Drei + react-three-fiber + Next.js stack. Although I have plenty of experience with React Native and vanilla three.js, my use of r3f has been limited to trying out some cool Drei features. Now, I’m working on integrating r3f, Drei, and Next.js together, and I’ve hit a snag.

When I try to re-instance a mesh with an already loaded texture using useTexture, the material doesn’t appear at all, and it only shows up after a hot reload while I’m trying to troubleshoot the issue.

The issue occurs when I instance a mesh (or multiple meshes) and fetch the associated texture via separate requests. Everything works fine the first time: I use useTexture to wait for the texture and useLayoutEffect to set attributes like flipY and colorSpace on the material, like in the example below:

TSX
function TexturedMaterial({ url }: { url: string }) {
  const imageTexture = useTexture(url);

  useLayoutEffect(() => {
    if (imageTexture) {
      imageTexture.flipY = true;
      imageTexture.colorSpace = THREE.SRGBColorSpace;
    }

    return () => {
      if (imageTexture) {
        imageTexture.dispose();
      }
    };
  }, [imageTexture]);

  return (
    <meshBasicMaterial
      map={imageTexture}
      toneMapped={false}
      onUpdate={(self) => {
        self.needsUpdate = true;
      }}
    /> 
  );
}

This component is wrapped as follows:

TSX
<OrientedAndResizedPlane
  objectDirection={objectDirection.current}
  objectSize={objectSize.current}
> 
  <ErrorBoundary
    fallback={<meshStandardMaterial color={0xff0000} />}
    onError={(error, info) => {
      // Optionally trigger a toast notification here
      console.log(`Error while loading texture: ${imageUrl}`);
      toast.error(`Error while loading texture: ${imageUrl}`, {
        richColors: false,
      });
    }}
  > 
    <Suspense fallback={<meshStandardMaterial />}
    > 
      <TexturedMaterial url={imageUrl} />
    </Suspense>
  </ErrorBoundary>
</OrientedAndResizedPlane>

The problem arises when I change elements in the scene, discarding the old ones and downloading new resources. When I attempt to upload textures that are already cached by Next.js, the textures simply do not appear in the scene.

I’ve tried all suggestions from ChatGPT and other AI sources—removing the dispose, using a custom loading function with Three.js’s TextureLoader, and managing state to force needsUpdate for both the material and texture. Unfortunately, none of these approaches solve the problem.

I’m hoping someone who has encountered this issue with Next.js and Drei can help me identify the problem. I suspect it might be a concurrency issue or a race condition in how the stack manages cached resources, but I can’t pinpoint the exact cause.

Thanks

Texture Loading Issue in React Three Fiber with Next.js

Based on your description, it sounds like you're experiencing an issue with texture initialization when reusing cached textures in your Next.js + React Three Fiber application. This is a common problem when working with textures that are cached by the browser or Next.js but not properly initialized in Three.js.

Potential Solution: Use WebGLRenderer.initTexture

One approach to solve this issue is to manually initialize the texture using the initTexture method from the WebGLRenderer. This method is specifically designed to preload textures and avoid the issues you're experiencing.

Here's how you might modify your component:

TSX
function TexturedMaterial({ url }: { url: string }) {
  const imageTexture = useTexture(url);
  const { gl } = useThree(); // Get the WebGLRenderer instance

  useLayoutEffect(() => {
    if (imageTexture) {
      imageTexture.flipY = true;
      imageTexture.colorSpace = THREE.SRGBColorSpace;
      
      // Initialize the texture explicitly
      gl.initTexture(imageTexture);
      
      // Force an update
      imageTexture.needsUpdate = true;
    }

    return () => {
      // Consider not disposing if you're reusing textures
      // if (imageTexture) {
      //   imageTexture.dispose();
      // }
    };
  }, [imageTexture, gl]);

  return (
    <meshBasicMaterial
      map={imageTexture}
      toneMapped={false}
      onUpdate={(self) => {
        self.needsUpdate = true;
      }}
    /> 
  );
}

Additional Considerations:

Texture Disposal: The issue might be related to disposing textures that are still needed. Consider removing the dispose() call if you're reusing textures.
Texture Cache Management: You might want to implement a custom texture cache to have more control over when textures are loaded and unloaded:

TSX
// Create a simple texture cache
const textureCache = new Map();

function useCustomTexture(url) {
  const { gl } = useThree();
  const [texture, setTexture] = useState(null);
  
  useEffect(() => {
    if (textureCache.has(url)) {
      const cachedTexture = textureCache.get(url);
      gl.initTexture(cachedTexture);
      setTexture(cachedTexture);
    } else {
      const loader = new THREE.TextureLoader();
      loader.load(url, (loadedTexture) => {
        loadedTexture.flipY = true;
        loadedTexture.colorSpace = THREE.SRGBColorSpace;
        gl.initTexture(loadedTexture);
        textureCache.set(url, loadedTexture);
        setTexture(loadedTexture);
      });
    }
  }, [url, gl]);
  
  return texture;
}

Force Renderer Update: You might need to force the renderer to update after changing textures:

TSX
const { invalidate } = useThree();

useEffect(() => {
  if (imageTexture) {
    // After texture is set up
    invalidate(); // Force a re-render
  }
}, [imageTexture, invalidate]);

This issue is likely related to how Three.js handles texture initialization and GPU uploads, especially when dealing with cached resources. The initTexture method is specifically designed to address this kind of problem by ensuring textures are properly initialized before they're needed for rendering.
