HDR RGBD Packed Cubemap Bug in Alpha 24 Build

I think it is because we are now using sRGB buffers by default in the glTF loader if the texture we load is a color data, meaning ITextureInfo.nonColorData = false for the texture.

If that is the problem, adding:

BABYLON.SceneLoader.OnPluginActivatedObservable.addOnce(function (loader) {
    if (loader.name === "gltf") {
        loader.useSRGBBuffers = false;
    }
});

should fix it.

A better way to fix it would be to flag your lightmap texture as a non color data texture because it really holds non color data.

So, before calling loadTextureInfoAsync, set:

commonConstant.lightmapTexture.nonColorData = true;
