How to import a Max Biped into Blender (https://www.katsbits.com/smforum/index.php?topic=779.0)For detailed info read "Import 3DS Max Biped (*.bips) into Blender (https://www.katsbits.com/smforum/index.php?topic=766.0)" here.Like other 3D applications Blender can't import 3DS Max Bipeds directly because they contains a lot of proprietary data. Instead characters, or models that make use of Bipeds, have to be exported by 'type' - mesh, armature, animations and so on - which can then be imported provided they're in a suitable format Blender understands.
