Okie, so I will give the sample for this case, so any one could test. Not only .FBX but also .X, the alternative way for porting skeletal animation in 3DGS
1. X version
Download .X version here This is a Standard X file. The bone influence is 3 maximum in vertex. But when import into MED, it reduces bone influence/vertex/1, the result like this.
2. FBX version
Download .FBX version here I use 11.2006 version, and will explain the result I get. The FBX plugin of Maya so there are no problem with this version file
When import FBX, there are an option, and if we dont check import bone, we get vertex animation

But if check, we get no animation, only BONE. There are an inform panel before importing finish

So could any one pay time to test these function too
