Hi.

I would like to represent the Sun. I don't want it to cast light. Just
need a yellow sphere crossing the sky.

Now I am using a pfGeode sphere but I get a shaded Sun.

What is, in your opinion, the best way to do this?

Some ideas I have:

-Should I be using a pfBillboard instead? Since the sun is spherical I
only need a circle, right? But this doesn't solve my shade problem!

-using pfLPointState with a single huge yellow light point should be
        the straight forward solution.
        Don't know if it's possible. The example lpstate.c is too
        complex and actually I'm a bit scared with pfLPointState.
        Is it possible to create a big light point? In the manual
        it mentions SMALL points only.

-I tried to disable lighting on the Sun object but I just got a
        white circle crossing the sky

-I'm considering pointing a light projector directly at the Sun so that
I don't see any shades but this seems like confusing what should be
simple!

please help me

thanks
        Nuno
