Troubleshooting three.js problem: Unexpected application malfunction in Chrome due to outdated code incompatible with the latest three.js library

Several weeks ago, my three.js (R48) applications were running smoothly until I encountered issues with Chrome where they no longer work.

Here are the initial error messages I received:

WebGL: INVALID_OPERATION: getAttribLocation: program not linked skyWheel.html:1
8
WebGL: INVALID_OPERATION: getUniformLocation: program not linked skyWheel.html:1
Could not initialise shader
VALIDATE_STATUS: false, gl error [1282] Three.js:355
29
WebGL: INVALID_OPERATION: getUniformLocation: program not linked

The applications still function properly in Firefox.

To resolve this issue, I decided to update to the latest version of three.js. However, when using the new version in Firefox, I encountered this message and the application failed to work:

[21:50:32.679] TypeError: material is undefined @ file:Three.js:23513

I am seeking assistance from someone who may have experienced similar problems recently and could provide guidance on resolving these issues efficiently.

Answer №1

Consider utilizing the minified version or developer version (three.min.js). This often resolves issues, even if they are using older versions. If not, I switched to using the canvas renderer and removed the spotlight, as well as disabled shadow mapping for the renderer. The issue was originating from THREE.WebglRenderer(). I recommend switching to THREE.CanvasRenderer(), although it may not provide the desired output.. :(

Answer №2

Significant changes have taken place since the release of version 48. For more details, refer to the migration page.
