HI here i am asking questions again…
i have to make high res skyboxes because i am making a RC flygth simulator like this one phoenix-sim.com/gallery.htm
i realy dont know from where to start making the skybox…
i have all the 6 immages prepared but i dont know how to make the skybox…
i have found some tutorials on the net but they are not specific and i dont know if i can use them in panda…
thanks for the answers and the patience…
(and sorry for my english i am italian)

I believe Terragen can create pretty good-looking skyboxes. Other than that, there are some tools for it but I’m pretty sure you can also google for some tutorials for the GIMP or Photoshop.
when i have done all the immage preparation how can i load it in panda?
do i have to load it as a cube map?
Sorry but i am a total newbie 
Making a skybox with terragen might be good for many games,but for a flight simulator it would be better to have 3d clouds.Though i cant tell you how,i still couldnt find enough info on the web.
After playing Just Cause at my friends,i was really impressed by the graphical part of the game(the physics and storyline are average).
Mostly by the cloud generator,the lens flare.They are just awesome.
Ill have a look at the link you gave…
