I am working on a project where we need a skybox render for every hour of the day, allowing us to use a slider in our project to change the time of the day. I was wondering if there is or a way to create a script for moving the position of the sun?

TheBadger

you can just set up an animation and animate the sun position. I guess you would want to turn off motion blur.

Then move the sun to each place at an hour and make the animation 24 frames.

If you scroll the page down, there is a little table with sun elevation + azimuth for every hour of a day  ... I suppose azimuth = heading for Terragen.
I have never used this data myself, not sure if it helps !

@TheBadger: Unfortunately, I do not believe that is what my project manager is looking for. Each time of day has to be a 5 sided skybox.

@paq: Thanks! I will take a look at it.

I have found how to script the suns heading and elevation. Now I need to find out how to script the heading and elevation of Plant 2.

ah ok. I was thinking spherical renders for lighting 3D, for some reason.
