Talk:Skybox (2D) with Terragen

Terragen, is not freeware, and making a sky 960 and then resize it to 1024, is not good at all. /hipshot

Of course, but you cannot use all functions if you don't have the full version, then its no longer freeware. And that is why he suggest using 960^2 instead of directly 1024^2 since the latter is not possible in the trial version. And as I see it, its better creating 512^2 skies with terragen if you can't make 1024^2 skies. All Valves skies are 512^2 and they work good. --Hipshot 05:27, 17 Sep 2005 (PDT)

Ok, now I changed the resolution from 960 til 512 and 2048 til 1024. Also, I removed the section about sizing up 960^2 textures to 1024. Its not good to rezise a texture upwards, the added information when sizing up a texture just makes it worse quality vise. Making a envmap 2048 with terragen is not recomended, the huge size is insane to render if you want maximum quality also, times six, since you need six textures to make a env map. The quality of terragen skies in high resolution can also be debated since its current cloud rendering, which is kinda bad. Six material textures, at 2048^2 would use a insane amouth of memory compared to 1024^2 and not to say 512^2.
