Loading two obj files but texture only shows on one

Hi,
I’m loading two ojb & mtl files that are supposed to be planets. Each of these will work fine individually, but when I try to load them both the texture is only showing for one of them. The other will just be a gray sphere. And LoadingManager said they all loaded in the console.

Here’s the snippet from the script:

var loader = new THREE.OBJLoader(manager);
var mtlLoader = new THREE.MTLLoader(manager);

function moonOBJ() {
mtlLoader
.setPath('assets/img/moon/')
.load(
	'Moon-2K-smooth.mtl',
	(materials) => {
		materials.preload();
		loader.setMaterials(materials)
		.setPath('assets/img/moon/')
		.load(
			'Moon-2K-smooth.obj',
			(object) => {
				scene.add(object);
				object.scale.set(13, 13, 13);	
				object.rotateX(-1.1);					
				object.rotateY(2.9);
				object.rotateZ(2);
			} 
		);
	}
);
}

function earthOBJ() {
mtlLoader
.setPath('assets/img/earth/')
.load(
	'Earth-2K.mtl',
	(materials) => {
		materials.preload();
		loader.setMaterials(materials)
		.setPath('assets/img/earth/')
		.load(
			'Earth-2K.obj',
			(object) => {
				scene.add(object);
				object.scale.set(30, 30, 30);
				object.position.y = -100;						
				object.rotateY(0.25);
				object.rotateZ(-0.3);
			} 
		);
	}
);
}

Both of these are from a stock site and created through blender. And they didn’t include the png sources in the mtl so I added those myself. I also changed a couple of other things in the mtl’s, such as opacities.

I’m lost on this. They’re coming from different directories so I don’t think they’re overwriting each other. Please let me know if anything else is needed and thank you for taking look.

Can you please share your repository with the full code? Without debugging, it will be hard to provide any feedback.

@Mugen87 After playing around with this for many more hours I found the problem was that everything has to be in the same mtl file. So “newmtl Moon” and “newmtl Earth” had to be in a single .mtl, not two separate files.

Still, thank you for your reply. I appreciate it.
