I am using a Makehuman model in blender, and rendering with cycles. As shown in the images below, I have used these nodes to put the texture of the tshirt on the person. There is a black spot on arm. What is the problem, how do I get rid of the black part?

  • $\begingroup$ well... as I thought your UV's are completely off. $\endgroup$ – Vitaliy Mar 30 '15 at 21:38
  • $\begingroup$ @Vitaliy, What do you mean by UV's are completely off and how can I fix that? $\endgroup$ – BetterEnglish Mar 30 '15 at 21:50

UV map is a coordinate system that helps to wrap a 2D image around your 3D object. You can read a little about UV's here http://en.wikibooks.org/wiki/Blender_3D:_Noob_to_Pro/UV_Map_Basics

Here is your situation.

enter image description here

What you see in white is your texture, exported from Make Human. The wires you see are your UV map. To look good they must match. I don't know how you ended up with sweeter when your character in Make Human had T-shirt, but I think this is your problem.

To fix it you need 1 of 2. Either edit your UV's to match the texture or edit your texture to match the UV's. You can read about the first way in the link I gave you, and you can edit the 2nd in any image editing software.
