I have done an MHX2 import into Blender of a MakeHuman created model. I see on the import a dark line along a part of the body edge at the thighs as shown in the attached image. I thought at first this is a shadow. But when I added a light to illuminate the thigh from the side the dark line was still there.
The image is a view the right thigh from the rear. There are two sun lamps shining on the model from the rear at different angles. Shadow is turned off.
I do not have any other objects than the MakeHuman import model in the scene that reflect light.
