Export to MUDBOX loses crease

I’ve tried to export my mesh in obj format and FBX format. My mesh has some edge creased ( shift+e function ) , but the information is lost during the export phase.
Is there any format that preserves crease information? Or something I can do to ease the process of importing mesh in mudbox?

Edge crease applies only with subdiv modifier, right? You can apply the modifier to get your mesh exactly as it is in blender to mudbox. If you want to build the detail up in mudbox you can try to get what youre after with smoothgroups. Use edgesplit modifier with sharp edges. Mudbox detail levels work different than blender subdiv and wont mess with the shape of your model when using smoothgroups.
