mcjDecimateEX is Ready !!!

i added a brand new functionality to mcjDecimate
called "LoopifyEndPose"
it may eventually be published as a standalone script

it takes the first 12 frames of an animation playrange, reverses it, and blends it with the end of the playrange animation
The way it's done, it transforms a non-looping animation in a looping animation

it doesnt have to be 12 frames, for a 128 frames animation i could have the reverse-blending be from 1 to 128 frames long

other notable feat, i used mcjApplique to keep the big buttons floating at the surface of the short pants without deforming
