Add Texture to babylon sample project

[Tanuky]

How can I add a Texture to the following sample

https://www.babylonjs-playground.com/#4GBWI5

I tried the following code:

		mat = new BABYLON.StandardMaterial("", scene);
		mat.diffuseTexture = new BABYLON.Texture("textures/texture.jpg", scene);
	//	mat.diffuseColor = new BABYLON.Color3(1, 1, 1);
			//mat.diffuseTexture.hasAlpha = true;
			build.material = mat;

I get the following error:

.WebGL-0x7f8fa201c400]GL ERROR :GL_INVALID_OPERATION : glDrawElements: attempt to access out of range vertices in attribute 1

Your model does not have UVs and UVs are mandatory when you rely on textures: https://en.wikipedia.org/wiki/UV_mapping

You should create them when you create the positions:

This is just an example, they should be created in a meaningful way. I just try to highlight the need of UVs here.
