Ok so the first step is creating a sky you like using the settings in the sun and atmoshpere settings.
Next click on render settings in the main window set atmosphere and cloud shading to high.
in the options tab of the same window turn of render landscape and backface culling.
in the image tab set the sky size to what ever you want it i use 512 * 512.back in the main window set detail to high.

open word pad and add the following code:

;Notes:
;~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
;The 3GSE engine will expect the images to be
;in the order of South, East, North, West, Down, Up.

;Set your render resolution to 512x512 pixels if you have the unregistered terragen.

;To make the lens flare line up with the sun in the terragen file, you would add

;Example:  Terragen has the sun at -60 degrees.  In WED you would assign it 60 degrees.

save as makesky.tgs

back in the terragen program select execute script and chose makesky.tgs

then open your image prgram and make a file with the same height and 6 times the width of you image, (i suggest ifranview) then paste the images in in the order of 1 2 3 4 5(should be blank) 6 save and your done!

original tutorial by steempipe.

i will try that, thanks for your reaction!

Very handy indeed, but this was contributed before by steempipe and can still be found on his website: http://steempipe.technicalfoundry.com/whitepapers.html

Hi Bilbo_Bogimps,

I have follow your instructions to build the skybox, but
an error popup after render the first picture :

Unable to open file!
Possible causes : folder doesn't exist or disk full.
Check the output settings for the script.

What I'm doing wrong? I'm so new in Terragen, please help.

PS : Can I only render the Blue sky without clouds?

Thanks again.

i know thats where i got it from... i couldnt remember the link or who submitted it tho so ill edit my post

Thanks, one more question, do you know
where I can find some tutorials for
Terragen. The manual doesn't described clearly.

Just a tip but the script by steempipe is very useful. I cut out the other directions (east, south, north and west) and made two more -one just for rendering the ground and one for the top when I wanted to just render clouds or terrain.

terragen isnt part of conitec try www.planetside.co.uk

To : Bilbo_Bogimps,

I've solved my problem just because of the typing error in the script,
and I got steempipe's skybox tutorial from his website, but still going
to find a way to not render those clouds and terrains.

Thanks everyone.

@vlau cant you just disable "render land"(or someting like this) in the render preview window?
