[Plib-users] Transparency?

[Tinoshi K. <ti...@li...>]

Hello!

I've got a problem with the clouds in the sky... I can't figure out why =
my clouds are ugly and those of sky.cxx are so beautiful... I've copied =
that code, except for the windowing: now I use PW... It seems that my =
clouds are not transparent, well, I see them and they are moving well, =
but they are 'flat', not puffy. Seems that their alpha is set to 1.0, I =
cannot explain that better. They seem pieces of paper flying through the =
sky, not vapour. Should I set some OpenGL state? I tried to use glut =
instead of PW but this is not the answer! It seems to me that in sky.cxx =
nothing of strange is set up, it's very 'simple', so i don't know what =
to do...
