How to change sun position
Hi,
I always fly using one of the photo-realistic sceneries (can't remember its name). I want to change the position of the sun because in this scenery it is always in front of me, I would like it to be behind me. Is there a way to do this?
Thanks

RE: How to change sun position
Hi,
sure its possible.
Each .geo file has a LIGHT_ section and the
LIGHT_POSITION 0 0.20 -0.40 1.00 0
is the line for the sun position
FIRST and last number (0) are not important, but the middle 3 set the sun location
0.20 north-south direction
-0.40 east-west direction
1.00 hight
but if you change it, it maybe doesnt fit the shadow given in the phote sceneries

RE: How to change sun position
Thanks Andi !!!
Since I've never messed with this before, can you please give me some pointers?
Do you know the range of values you can play with? from -1 to 1? does "0" means sun right on top? etc?
I asssume that the .geo file is a simple text file that I could modify in the notepad. Is this correct?

Hi,
yes, the .geo is a simple text file, allways make a copy before playing arround with this files.
north-south direction --> -1 till 1 - = south
east-west direction --> -1 till 1 - = east
hight --> 0 till 1 1 = 90 degree, right on top

RE: How to change sun position
Thank you very much.
Itried it last night and it worked perfectly.
(Well, almost... my scenery sky now has two suns; the one a moved behind me and the one from the actual photo, hahaha)
Nevertheless it helped since the reflexions and plane shadows are more realistic of the way I fly in real life.

RE: How to change sun position
You might want to remove the sun from the original scene (the pano before you install it into the program) with the clone tool in Photoshop. That way you would only have the sun that is generated by the program.

RE: How to change sun position
Sorry for the delay in responding. What is the name of the scene that you are using? Is it one of the scenes that came from IPACS "the guys that wrote the program" or something you down loaded?
