| Quote (Salvo) If it possible in the same way you could make the transition of some biomes just a bit smoother, for example sand and snow, because now is a bit unrealistic
It is not "the same way". And no, transition between snow and sand/rocks must be hard. Where did you see the smooth transition between them?

There are indeed some regions where such hard transitions are visible, it is a bug, I don't know how to fix it, and left it as it is, I thought having hard transitions somewhere is not bad.

| As you've probably noticed, SE doesn't take into account the color of the planet when it calculates the illumination of moons (and vice versa). Now I've fixed this. The method is very tricky. Analytic calculation of color of the planet is almost impossible - it should take into account the color table used for the surface texture generation, clouds and water coverage, and atmosphere color. So I made things easier - I just render a planet into a small texture (viewed from sun, so it's at full phase), then it read this texture back to CPU and sums up all pixels to calculate average color. This gives the true color of the planet taking into account all its features - real surface texture, clouds pattern, atmosphere and even rings!
This procedure is fast enough, so it even can be used for real-time update of a planet's color. I've implemented several settings - compute color once, when planet first comes into view of field, update color every half second, and disable updating color. In the real-time updating mode, the effect fixes full eclipse issues - when the moon is in the shadow of the planet, it does not illuminate the planet.
Another thing is the distance from which the color should be calculated. Now we should be able to approach the planet to see its disk. After that, if you leave the planet, its star-like particle will have a proper color. It is possible to calculate the color of every object from any distance, but this may hit performance, because there are hundreds of objects in a typical planetary system. It is also possible to calculate a color for every body when a planetary system is being generated, but this also will increase the generation time.
Here are the screenshots showing the same scene, before and after a planet's color calculation (view it at full size). The first two are a view on a blue gas giant from its moon, and the next two are from far away, where it looks like a star (note the color of some small yellow moon near the gas giant):

| Very odd... I thought this was already implemented. Check out the difference in illumination of Phobos and Naiad:
I suppose that so far it's only implemented in our Solar System, then. It'll be great to see it expanded to procedural worlds!

This is not an in-game screenshot of the new version, right? This is a photoshop image, right?
And regarding the correct color illumination of the planet's moons: Can't believe that you also did this! What should we expect from version 0.98? You are so much spoiling us  !

No, for some Solar system objects color was put in the catalog manually (check the SolarSys.sc). Otherwise it was assumed to be white.

| Forgot to mention: in the real-time updating mode, the effect fixes full eclipse issues - when the moon is in the shadow of the planet, it does not illuminate the planet. However, I should solve this issue analytically, by upgrading the eclipse code.

For this purpose, planet scripts have the parameter Color. For procedural generated planets, this color was always white. So now this script parameter is no longer necessary.

This is screenshot of course.

| If a blue planet is iluminated by orange light (by a red dwarf, for example) the moon will be half orange and half blue?
