Took a while, but URG! 5.6 is in internal testing phase.
After a few time consuming technical drawbacks, we've once again implemented ground breaking functionalities in the most reliable and famous ragdoll tool for Unity 3d.
Hand and feet exploration are live and awesome, and together with the armature eploration rework (with live drag and drop preview), your ragdolls will be easier to perfect, and will look even cooler than before.
Additionally, full support for daz, iclone and mixamo armatures (with multiple skinned mesh renderers) is icing on the cake.
