I know HaloSim but in which way is it possibile to transfer the results in Terragen? And about distorsion of sun and moon near the horizon? There is some way to make these effects with TG2? or with other render programs?
Thanks for your patience.
You set the all the HaloSim background colors (sky, horizon, etc.) to black and disable things such as the horizon line. Then, when the program generates the halo you have it on a black ground. Save the image and place it on the TG2 rendering as a layer in Photoshop. (You will probably need to adjust the size so that the angular diameter of the halo is correct for the visual angle of your picture.) Set the layer for Screen, which will make the black transparent. Depending on how many rays you chose for HaloSim to use, you will probably need to blur the layer very slightly in order to blend the points together.
I don't know of any program that will do the kind of flattening of the sun and moon you want. I myself would probably just create and insert them in Photoshop. That would, I think, be the fastest, simplest and most direct method. In several of my extrasolar planet renderings, I replaced the TG2 sun with a sun I created myself (or a moon as the case might be).
Here is an example of where I did that...
