Celestia Forums

Ok, I'm working on my first add-on for Celestia. Lets just say something is getting terraformed I know how to make an alternate that can be switched between the original texture, but is there a way to turn the Atmosphere, Haze and clouds off and on when switching to the alternate surface texture?

Unfortunately, no. It's only an alternate Surface texture.

You can put different clouds in the hires folder and toggle them by typing R or r

John Dollan has recently made some excellent versions of various Orion's Arm planets in their preterraformed and post terraformed state; I have made an .ssc up for them which has an Ending instruction for the preterraformed version, and a Beginning instruction for the post terraformed version. They have alternate cloud and specular maps etcetera.
The instruction for ending can look like this


Intermediate stages can be included as well if required; you then can visit each version by using te 'Set Time' function in the toolbar.

These versions should be available at the Motherlode soon.
