Yes, set the material of your sky sphere to have no specular component. > If I put lighting OFF, the opacity do not seems to work... Did you use GL_BLEND and TRANSPARENT_BIN as David said ?

I don't understand your sentence... (sorry). Do you mean you wish your sky sphere to have a transparency that you change over time? If so, there nothing special to do. Just try to make transparency work when disable lighting. > Thanks for help. De rien (= you're welcome = de nada = etc.).
