BonesPro > export skin problem


My bones pro rig works perfectly. But, as soon as I use the “export skin” function, the vertex’s of the bones-pro generated skin modifier, are getting only partially weighted correctly (in a gird pattern look. I can’t find anywhere threshold options. I am using simple bones, since i have my issues with cat & biped.

Does anyone have experienced the same problem? I am using 3dsmax 3014 and bones pro 4.6 (26629)

Thanks in advance!
