Doesn't present in 1.6, but present in all 1.7 versions.

Those URLs don't work in 1.6.1, but it does have the same problem.

[375gnu]

@SevenSpheres just change ver=4 to ver=3 and they will work in 1.6. Could you also provide URL and screenshots for 1.6.1?

[SevenSpheres]

With the same URL changed to ver=3 I see this:

It doesn't look exactly the same, but the surface of Mars disappears at that angle.

hmm, i have correct image, but i don't have textures for Mars installed in 1.6.1, i'll checkwith textures installed

The issue is reproducible with 1.6 as well but the latest data is required.

The root cause is a near plain clipping. Renderer::buildRenderLists / Renderer::buildDepthPartitions should check if objects have low height and merge their depth partition with the parent body's one.
