MTL file with jpg cause errors (FIXED)

firecloud · June 14, 2021, 8:18pm

So I did this tutorial:
Learning three.js 01 :: Getting Started - Learning three.js 01 :: Getting Started - YouTube

It shows you how to make a simple first persoon shooter. Everything was fine and I build my first game where I could walk arround. Until I tried to add my own OBJ + MTL files… These MTL files contain .jpg textures. Everytime when I add the MTL file the scene doesn’t start. I think there’s something wrong with the loader but I can’t figure out what…

This is the loader I’m using:

github.com

saucecode/threejs-demos/blob/e70939184d1b4fd2150ea7dfa4b9051fb8d4a531/MTLLoader.js

/**
 * Loads a Wavefront .mtl file specifying materials
 *
 * @author angelxuanchang
 */

THREE.MTLLoader = function( manager ) {

	this.manager = ( manager !== undefined ) ? manager : THREE.DefaultLoadingManager;

};

Object.assign( THREE.MTLLoader.prototype, THREE.EventDispatcher.prototype, {

	/**
	 * Loads and parses a MTL asset from a URL.
	 *
	 * @param {String} url - URL to the MTL file.
	 * @param {Function} [onLoad] - Callback invoked with the loaded object.
	 * @param {Function} [onProgress] - Callback for download progress.

This file has been truncated. show original

This is the error I’m getting:

Uncaught TypeError: Cannot read property 'setCrossOrigin' of undefined
at THREE.MTLLoader.MaterialCreator.loadTexture (MTLLoader.js:467)
at THREE.MTLLoader.MaterialCreator.createMaterial_ (MTLLoader.js:393)
at THREE.MTLLoader.MaterialCreator.create (MTLLoader.js:329)
at THREE.MTLLoader.MaterialCreator.preload (MTLLoader.js:297)
at index.html:175
at Object.onLoad (MTLLoader.js:36)
at XMLHttpRequest.<anonymous> (three.min.js:6)

What does this mean and what can I do to fix this?

All advices and tips are welcome. I thank you in advance for the help.

Update:
So I’ve changed loader === null to !loader in MTLloader.js. This made it all work
