one question to the *.x IMporter though:
i have an x-file exported via Xport for c4d, it contains an animation (bone anim) which is not read by MED. why? it's and ascii x file, the anim lines look like

template AnimationKey {
<10DD46A8-775B-11cf-8F52-0040333594A3>
DWORD keyType;
DWORD nKeys;
array TimedFloatKeys keys[nKeys];
}

template AnimationOptions {
<E2BF56C0-840F-11cf-8F52-0040333594A3>
DWORD openclosed;
DWORD positionquality;
}

template Animation {
<3D82AB4F-62DA-11cf-AB39-0020AF71E433>
[...]
}

template AnimationSet {
<3D82AB50-62DA-11cf-AB39-0020AF71E433>
[Animation]
}

AnimationSet {
Animation {
AnimationKey {
4;
100;
0;16; 1.000000, 0.000000, 0.000000, etc. }
{Wuerfel_0}
}
and the same with other figures and {Bone_Objekt} at the end.

don't ask me what it all means, Xport did it. i just wonder why it doesn't include the animation, though the frame names and the mesh come out fine.
