is your folder close to root, and does not contain spaces?

yes

D:\Hallways\


Btw.. i managed to import a 3Ds.. but as i said.. no Skin mapping (the skin manager is empty).. and all normals are randomly flipped >.<
God i hate MEDs Importer Tools!!!

hmm... and what if you use c:\Hallways\ ? I'm just interested.

same problems ._.

i tried reinstalling MED yesterday.. but that didn´t solve the problem

I just tried importing it to med. I think the problem with the texture is, MED uses a single texture for the whole model and you use lots of texture throughout the model. Have you tried merging or baking everything together?

Btw, your FBX gives me no errors in MED, just the unfitting textures.

edit:// I see you already "fixed" it. Looks very nice. Now I wonder if my "one texture" theory is correct at all.

I checked in skin editor and there were no uv coordinates set. materials and textures were imported fine.
anyway, nice work

okay
i tried now to inport several fbx files..
a cube created and skinned via C4D
a cube with 3DSMAX
a cube with Wings3D
a cube with MED export to fbx

all 4 cubes arw giving me the same FBX Importer Error when trying to import them into MED..
i rhink the Importer is broken..
Suspect, it has not been repaired by reinstalling A8 ._.

Have you tried on another computer? Or in another installation directory? Like in C:\Tools\ or something outside the restricted Programm Files directory.

C is only for windows on my PC
all my Programms are installed to D or E

i tried on my Laptop - there it works ._.

I just read in the manual:

Cinema 4D® properly exports to FBX only when the textures are stored in .TGA format.

so have a try with tga
