So, I have read the ultimate shader thread, pretty cool, and I've downloaded Nvidia Fx Composer, but I'm still struggling.
FX composer either crashes on me mid way through building a shader, or I finish and find it won't work.
I'm just after a planet atmosphere shader (this one is the important one), and possibly the corona shader that you find in FX composer to apply to a sun (This would be a nice to have, but not majorly important right now).
Can anyone help? I've wasted a lot of time in Fx Composer so far for no joy and am ready to just forget about shaders totally.
It's not my fault!
