I'm taking a quick look ...

Got it working with this script (win32 and Android)

var camera = new BABYLON.ArcRotateCamera("Camera", 0, 0.8, 90, BABYLON.Vector3.Zero(), scene);
camera.lowerBetaLimit = 0.1;
camera.upperBetaLimit = (Math.PI / 2) * 0.9;
camera.lowerRadiusLimit = 30;
camera.upperRadiusLimit = 150;
//camera.attachControl(canvas, true);

var light = new BABYLON.HemisphericLight("dir01", new BABYLON.Vector3(0, 0.3, -1), scene);
light.intensity = 0.9;

// Ground
var ground = BABYLON.Mesh.CreateGroundFromHeightMap("ground", "https://playground.babylonjs.com/textures/heightMap.png", 100, 100, 100, 0, 10, scene, false);
var groundMaterial = new BABYLON.StandardMaterial("ground", scene);
groundMaterial.diffuseTexture = new BABYLON.Texture("https://playground.babylonjs.com/textures/ground.jpg", scene);
groundMaterial.diffuseTexture.uScale = 6;
groundMaterial.diffuseTexture.vScale = 6;
groundMaterial.specularColor = new BABYLON.Color3(0, 0, 0);
ground.position.y = -2.05;
ground.material = groundMaterial;

It's copy pasted code from https://playground.babylonjs.com/#CQNGRK#0
That is being used for validation test.

IIRC @carolhmj you were using a different image. Can you please upload it somewhere?

@CedricGuillemet , are you testing on BabylonNative? I was able to get it working on Babylon Native as well but the problem happens when using it on Babylon React Native.

[CedricGuillemet]

Got the exception : "LoadFileError: Creating blobs from 'ArrayBuffer' and 'ArrayBufferView' are not supported"

[bghgary]

Issue supposedly only happens with Babylon React Native
