Definitely looking better. I think using light definitions to auto generate the cubemap is rather limiting, which is why I was interested in loading the map (in this case 6 textures) from disk. These days it's trivial to just jump into 3ds max, maya, modo, etc. and generate environment maps that work better. Just place a camera with the proper projection settings in the middle of a scene and render it out. You can see how easy it was to make the chrome example DesuDeus posted, and the results are much more appealing, imo. Plus you aren't limited to standard lighting setups and can achieve any kind of effect you want (e.g. place the camera inside a procedurally mapped sphere and give it a soft diffuse plasma look).
