howto matching the motions of source actor of neuron mocap with the stylized iclone's character?

my biggest problem is matching the motion arms and hands of neuron actor with iclone's stylized character like as tokomotion characters ... arm and hand going into the body or face :\

is it possible to retargeting inside iclone? (like as ikinema for motionbuilder?)

You can edit position Arms/Hand with the "Edit motion layer" Tab.
Suggestion: When performing with actors and the Neuron suit , it's helpfull to Broadcast live
inside Iclone with your stylised character. The performer can see the space limit moves to not
penetrate the character shape.

yup ... i'm just using live broadcasting ... and i'm performer :]

but it's very hard to matching me with characters :\

is it possible to define joint rotation limitations for iclone character?

I don't know for the joint limitations.
Don't forget to setup your body profil in the axis Neuron with your real body measurements, it helps.
Like in "hollywood" I suggest also  to put real props on your body to simulate the avatar size body.
The more you're accurate on reccord the more you save time in edition.
Yes motion capture  take practice performance for fast/good result 

I don't know at what point the Perception Neuron Plug-in was fixed, but things are working now (with the pro version of Axis)!! I did download the latest version of the plugin from my reallusion account and I also updated the firmware on each of the neuron sensor so I'm not sure if any of that had to do with it as well.

The main problem now is with the mocap sensors and calibration inside Axis software... so janky, especially with the feet and the fingers.  No matter how many times I run the calibration, fingers are curling and feet are like pigeon toes!  Nothing to do with iClone though...

I'm glad the plugin doesn't crash anymore!  Hopefully it all still works with iClone 7 =)
