I am trying to use the MTLLoader and I’m not sure why but it breaks the rest of my three.js code and the texture don’t load all the way and don’t look right. Everything works when I use the OBJLoader by itself. Specifically it messes up the camera so it doesn’t work. Any guidance would be appreciated. I am using the latest version of three.js that is offered from the three.js website.
here is the error code I get
three.js:24415 Uncaught TypeError: Cannot set property ‘value’ of undefined
at initMaterial (three.js:24415)

at render (demo2.html:516)
Here is my MTLLoader code
var mesh = null;
var mtlLoader = new THREE.MTLLoader();
mtlLoader.load( 'dapHouseGood5.mtl', function( materials ) {
materials.preload();
var objLoader = new THREE.OBJLoader();
objLoader.setMaterials( materials );
objLoader.load( 'dapHouseGood5.obj', function ( object ) {
mesh = object;
scene.add( mesh );
});
});
here is the rest of my three.js code for reference
