I'm found how to do this in GIMP(i'm gonna upload modified galaxi textures to celestiamotherlode), but in Photoshop CS is not possible to make alpha chanel - it's very uncomfortably!

t00fri , please ansver me: how to make black bacground to be transparent? I mind not edit blend in layer style , bacause it produced bad results (some pixels removes and black background remayn). I need convert level to Opacity ! In example: some textures for galaxies (celestiamotherlode) has trans...

Yesssssssssssss!!!! I found the Celestia's BUG! (I mind). If color dephth of textures is 32bpp (in .png format only!), then it's wirk! If color dephth is 24bpp then ANY textures (surface/bump/normal) is do'nt load and not work! In's all, my problem is down! The safe of drowings is affayr of them own...

But with wery long delays between show next screen (wery low FPS i mean). If i reduce resolution of it's image (norma...

I download EarthBump & MarsBump files, plase it in to Celestia\textures\medres folder, and edit solarsys.ssc file, but surfaces of planets stay flat! It's not work! What can i do with this? And second question: 'normal map' - what is it, and how use it? My system is Athlon XP 2500+ FX5700 DDR320...
