300MB FBX file from Zbrush export becomes 1.5 GB FBX file when exported from 3dsmax

[OccultMonk]

When I export a model from ZBrush in FBX format it's about 300MB. When I import that model into 3dsmax and export it again it is 1.5GB. (In the FBX Settings I have everything disabled, no textures or animations). It's exactly the same model as in zbrush, NO modifiers or textures, animations added.

Was probably caused by the wrong FBX format setting: ASCII instead of Binary.
