I started making texture maps for planets yesterday, and I've run into a problem. Actually, I ran into this countless times when playing with the planet textures and models on Sci-fi 3D, but I just ignored it then. In this case, a picture is worth a thousand words, so I'll provide a few of the former. [image=http://www.angelfire.com/alt/3d-duckboy0/Planet_04.jpg] As you can see, the texture map I made is curving inwards at the top due to the lack of space compared to the amount of texture. That's using spherical mapping or none at all. [image=http://www.angelfire.com/alt/3d-duckboy0/Planet_01.jpg] This one is using box mapping. Produces very undesirable results.

It looks incredibly unnatural, although most everything blends better.

So what's the deal? Does anyone know how to compensate for this when making the texture? Or am I just going to have to live with it?
