Normal Map Intensity?

[SpaceToast]

Is there a method of altering the intensity of a bump map (normal map) from within Babylon.js? Something along the lines of:

 

    var bumpyMaterial = new BABYLON.StandardMaterial("bumpy", scene);

    bumpyMaterial.bumpTexture = new BABYLON.Texture("bumpy_normal_map.jpg", scene);

    bumpyMaterial.bumpTexture.alpha = 0.5;

 

More generally I suppose, how would one fade a texture map of any kind during runtime?

All textures have a "level" variable, you can use it to slowly "fade in" the texture.

bumpyMaterial.bumpTexture.level = 0.5;
