I'm still here. And after moving, handing in a thesis and working a lot I finally had some time to work on skyboxes again. Yeay
I also just realised today that I can use a simple cylindricalk UVW map for lightmaps and don't have to use a multi-unwrap script followed by somehow projecting a cylindrical map and rendering that to a texture. With that roadblock out of the way I was able to get a lot of work done for Taris. The backdrop buildings are now lightmapped to blend with the skybox:
For comparison. Here's the same without lightmaps:
In that case one would of course change the color for the texture but you can also see the change in "lighting" in the lightmapped image from left to right. That would have been impossible with a single backdrop building texture and no lightmaps.
Now I just need to figure out what those weird white rectangles floating around the upper city are and get rid of them. I might also tweak the lightmap some more, especially for the Upper City South. And I need to check if everything still looks good once I render the skybox with all clouds enabled.
Apart from the lightmaps I also did something else today. I'll show it in a screenshot and for some reason I'm feeling like making a guessing game out of it. Please don't ask me why. I'll post some hints in spoiler tags below and if you don't feel like guessing, you can just open the answer-spoiler^^
That's it for now, so all that's left for this post is me wishing you all a MERRY CHRISTMAS!
