I'm currently working in Blender 2.78 using cycles trying to create a realistic toroidal/doughnut planet. The problem I'm having is mapping an image onto a torus.

The result should be something like the picture below.

A toroidal planet

    $\begingroup$ I have tried unwrapping the torus after making seams along an equator and a meridian in the uv editor. I have also tried only making one seam along a meridian and unwrapping as a cylinder. $\endgroup$ – Gregorick Sep 4 '17 at 19:15

    $\begingroup$ An option is to map the image into a subdivided plane and bend that plane to make a torus. See: blender.stackexchange.com/questions/39735/… $\endgroup$ – cegaton Sep 4 '17 at 19:30

    $\begingroup$ I see the thought did occur to me to do that. I will test it out and let you know if it's successful. $\endgroup$ – Gregorick Sep 4 '17 at 19:40
  • $\begingroup$ Your method worked very well. Thank you very much. $\endgroup$ – Gregorick Sep 5 '17 at 3:47
  • $\begingroup$ I think your original marking of seams would have worked fine if you had used the Follow Active Quads unwrap method with a "corner" face selected and active. $\endgroup$ – Mentalist Sep 6 '17 at 9:29
