oh, sh*t! Just readed now, that BS 2.6 doesnt support rig import. How can I playback animation in Maya without it?
Found some useful info about poser character exporters with rigging support, but they can't reproduce same rigging quality as Poser and Daz, because poser use own rigging system.

This is the quality of rig convert of latest Daz FBX plugin:

Great quality, isn't it? Other exporters is not far from this.

I don't have needed experience (I more into music creating than in 3d) to make same quality rig as in poser, so I'll stay in Poser and shall look how bopperthijs and Tguyus methods works. Thank you guys for research.

bopperthijs: can you say what morph names need to spawn for Viki4.
