Texture baking question

[x64]

I thought it would be a good idea to use baked textures for performance sake however I don’t know how to not use lights and still let it be lit so the baked textures work. When using ‘MeshBasicMaterial’ this doesn’t get affected by light so is there a way to achieve this for an imported gltf file?
This is the code of my model loader:

//Load model
const loader = new GLTFLoader();
loader.load('PortfolioDesk.glb', function(gltf) 
{
  console.log('loading model');
  const object = gltf.scene;
  object.traverse((child) => 
  {
    if (child.isMesh) 
    {
      child.castShadow = true;
      child.receiveShadow = true;
    }
  });

  object.position.set(0, 0, 0);
  scene.add(object);
  document.getElementById('progress-container').style.display = 'none';
},

In Blender if you plug in the baked texture image now directly to the shader output, the gltf material will be exported as unlit basic material iirc (cc/ @donmccurdy I think he mentioned that)

I’m still kinda new to blender, do you mean like the top example in the image? The bottom one is what it is currently for all objects.

Yup - the top one should export a basic, unlit material.

I love when things are this simple, thank you!!

One more question that I didn’t really want to make a new topic for, how does this work when I need to change the alpha value? Before the alpha from the image went into the alpha in the BDSF but now that I don’t have the BDSF I can’t change the alpha value. There doesn’t seem to be a node that just changes alpha.
