Hi everyone! Was wondering if anyone could give me any tips on how to best approach the making of craters on a spherical planet (meaning seen from space). The render size is gonna me really small (150x150) so I don't really need any detail, just believable craters. How would I got about joining them onto a sphere?

"Dis - place - ment". That's what I would use methinks.

It's obviously not going to be overly tricky having proper UV coordinates on a sphere, and then you 'just' have to come up with a proper displacementmap. This could be generated entirely procedurally, which I know Allan McKay has some awesome tutorials on, over at 3dluvr.com. Or you could handpaint such a map of course.

..come to think of it I'd prefer a mixture of the two I guess, you can handdraw the basic contours and placement of these craters, and set up a shader following Mr. McKay's suggestions that puts in procedually generated smaller details.

Sounds so easy in theory.. :)

Very simple :)
Sphere -> Editable Poly -> Chamfer vertex -> Some bevels -> MeshSmooth.
