As I mentioned last time, I was going to tweak the Tatooine skybox some more even though I had considered it almost done quite some time ago.
The reason for that was that I had never been able to really match the skybox lighting and sand color to the ingame terrain. I had come closer with V2 than in my initial release but I wasn't really happy with it yet, so it had been on my agenda to go back and fix that. You can see that in the following image.
As you can see the shadow parts of the dunes are way too dark so they don't blend with the foreground terrain at all. So I set out to fix that and now, approximately a hundred iterations later I finally arrived at a result I'm happy with.
The lighting in the game is very cheaty with several different light sources creating that yellow-orange-ish light, making it impossible to replicate that with two suns and a uniform sandcolor as I had it in the skybox. I considered changing the ingame lighting for a while but that didn't turn out any good so in the end I just cheated myself. I added a third sun that lights only the ground and recolored individual parts of the sand dunes to get the correct colors in every direction. It took a lot of iterations but now I'm really happy with the result.
While doing so I also realised that the skybox terrain didn't match the ingame one either. You can kinda see that on the screenshot above although it was more obvious in other places that the skybox dunes were just too small. So I widened those as well. That cause issues with the overcomplicated and unflexible way the terrain was set up. This was after all the very first terrain I ever created in Terragen and hasn't really changed much since then. So I basically rebuilt the terrain. You don't see that in the end result but it's working much better now.
But I guess that's enough talk from me and you want to see some screenshots. So here you go:
It's the same perspective as before but the terrain and skybox blend much better. And just for fun, here's another screenshot:
That's another skybox checked off and thus almost finishing K1. Only Manaan underwater and a few fixes here and there remain.
