Hello, first excuse my english.

I have few characters and few animations, i do with maya 2014 (no humanik), now i thinking in try something like ipi for new animations, but i don't want to do the work done again and all characters have diffent bone names for use with IPI.

my question its, can i use in any way the IPI generate animations with my already done stuff?

my knownledge with animations/maya ins't big, i work with maya/animation for few months.

You can transfer motions on any (biped) custom rigged character.
For non-standard bone names, you'll just need to setup the bone mapping manually on the Export tab in Mocap Studio.

ok if i understand right at export i can change example LHAND to L_HAND right?

Mocap Studio does not change joint names, but maps joints of built-in skeleton (with fixed names) to joints of your custom character (with arbitrary names). For example, you can map the 'LHand' joint to your character's joint named 'L_HAND'.
Mocap Studio includes pre-defined mappings for several widely used joint naming conventions. If your character follows one of those conventions, then you may not even need to set any mappings manually.

then i suggest support (i don't known if have) for Unreal Egine 4 + ART bones.
