'm a bit curious about how you make the chrome surfaces...

You have to edit the [font=courier new].obj file[/font], and change the material description to mirrors.
There's an old thread that explains this somewhere on the forum, but it seems I'm not able to find it right now.

...avoid getting all the white spots that usually appears on shiny surfaces

Mostly by repositioning the light sources and setting the [font=courier new]shininessShader[/font] to glossy.

Adapting is the key to survival [;)]
