Box Color Changes When Flat on Orthographic Top View? How?

You can see the exact problem here Recording #504

Why is the color white when the box is flat? My guess is that it has to do with the lighting I use?

var light = new BABYLON.HemisphericLight('light1', new BABYLON.Vector3(0,1,0), scene);

var box = BABYLON.MeshBuilder.CreateBox("box", {width: 2, height: 2, depth: 2}, scene);

let blackMaterial = new BABYLON.StandardMaterial("blackMaterial", scene);
blackMaterial.diffuseColor = new BABYLON.Color3.FromHexString('#000000');
box.material = blackMaterial;

Hi. Actually the color is not changing, you are seeing specular effect of the hemispheric light on the material of the box.

Use this

light.specular = new BABYLON.Color3.Black():

that should fix that issue

Also, if you don’t want to completely remove specular of the light, you can set specularColor of the material itself to black, it will have same effect.

So

blackMaterial.specularColor = new BABYLON.Color3.Black();
