This will make it so when the Sun's heading is '0', the light_environment should also be "-[height] 0 0" | |||
I don't know why this is, or maybe I'm wrong; but it seems to work properly so I can copy directly from TG2 into source and the sun will aim correctly. --[[User:Glitchvid|Glitchvid]] 02:02, 27 October 2013 (PDT) | |||

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

Correct Terragen 2 camera angles
I've noticed that (at-least when using TG2) the camera angle aren't correct; they need to be offset. Here's the proper angles:
0 270 0 Front 0 0 0 Left 0 90 0 Back 0 180 0 Right 0 0 90 up 0 0 -90 Down
This will make it so when the Sun's heading is '0', the light_environment should also be "-[height] 0 0" I don't know why this is, or maybe I'm wrong; but it seems to work properly so I can copy directly from TG2 into source and the sun will aim correctly. --Glitchvid 02:02, 27 October 2013 (PDT)
