I have little experience with Area Light so far, but maybe it's worth a try.
But the render time increases again.

I started with meshes because I found the rock generator and wanted to try it.
I would not have thought that you would see the triangles so well.

Here in the forum I found an isosurface asteroid and it actually looks quite
good, see picture.
Maybe I can improve it further, use it as an object in the foreground and
because of faster rendering time use the meshes for more distant objects.

I also looked for textures, which I didn't find right away.
I came across this page that shows the built-in textures, very helpful.

I have to take a closer look, looks like more training time.

Thanks for all the tips.
