thx for your help. where do i have to Chose ascci 6.1? I tried it with Import fbx (2010)(propably not what u meant) and he told me that "the Skin size (1131 x 1700) is not a power of two!"
, textures of models should be a power of two, so e.g. 32x32, 128x128, 256x256, 256x512, 512x512, 1024x256, 1024x1024 etc etc. So resize or crop your texture to power of two, than in Blender export as fbx and in MED import as fbx (2010).
