I wonder if any of you know a good tool for painting seamless skybox textures. Especially plugins compatible with Photoshop CS4 (yay!) would be awesome.
I know about skypaint, but the tool is really a pain to even get to work nowadays. There must be some alternative? What would Valve use to do the TF2 skies, for example?
PS: I know about Terragen. My question is about editing and tuning the resulting images while still keeping the correct perspectives.

You can try following Aaron's Seamless Texture Creation Tutorial maybe? It's a very nice tutorial 
(No I don't know if that also works well for skyboxes, but it's worth trying out I guess)

The trick is to get the perspective distortion right, which goes a few steps further. For example, if you just copy in a photo of a cloud, it will look like it's a sticker on a flat wall.

That's what the tutorial is for. http://www.snarkpit.net/snarkpower/articles/game/cat/pn/tp/196/Seamless_Texture_Creation
Or are you talking about the skybox part where it goes from left to front and from front to updownright etc?
lol sorry I'm not the smartest one here

Thanks Niborius although reaper47 is talking about making a 2D skybox (yes the left/right/up/down/back/front thing) so this tutorial isn't much use.
I'd also like to know more about 2d skybox creation.

Oh I see.
Well then I know nothing about those, though you can make a panorama picture and make it a skybox.

Generally Terragen, even the free version, can do pretty much anything you want when it comes to natural looking landscapes and clouds. Check out the tutorial I linked in the first post.
But I recently tried to copy a picture of the moon into a rather simple night sky and it was a royal pain in the ass. It's a perfect circle, but unless you plant it into the middle of one of the six sides (which you mostly don't want to do), it will look slightly distorted/oval, but enough to look really bad for something as prominent as the sky. Oddly enough even adding stars (dots!!!) looks bad and flat!
I find it pretty strange that there are no plugins for this. I searched teh googel, and only found a few super-complicated conversion tutorials, but no actual tool to "paint in perspective". The whole QuicktimeVR scene should have spawned something useful, but it's really, really hard to find.

Hi reaper, I went thru exactly that while making a night sky w/ a moon. I ended up having to get it close by trial and error in PS. It was for a night version of Shipshape, I got it to the point where it would be circular if you looked straight at it. I posted some screens but they got lost on the site recently.
There really was no way I could find to eliminate the FOV distortion completely short of making a sprite for use with emv_sun, which tbh I didnt try... Let me know if you want to check it out for fun.
