Is there an easy way to create dances?

You want to use the IMVU Biped animation rig and 3DS Max. There are options other than Biped, but Biped will ultimately give you the most control. Using IMVU's Biped rig is a great way to turn Max biped animations or motion capture files into IMVU skeleton animations. The Biped influences the bones of the skeleton. For example, move the biped and the IMVU skeleton's bones move.

You will also need the basic biped animation rig for IMVU: https://www.imvumafias.org/dl/3dsmaxsamp ... _Basic.zip

Watch some 3DS Max 2016 Biped Rigging tutorials on youtube, since I know that is the version of 3DS Max you are using: https://www.youtube.com/results?search_ ... gging+2016

Finally here is a backup of all of the threads covering biped rigs from the original IMVU forums, from before IMVU took down their old forums filled with valuable development tutorials: https://www.imvumafias.org/dl/IMVU%20Biped%20Threads.zip
