heyas; spherematsraw are the 'use spherical falloff zones' things. if you open the jp window in poser, you'll see pretty much the same info that is in the cr2 text jp (the joint/joint/twist). for example, on a twist bar, you'll see the high end and low end and start or whatever. on the bend x, you will see the dynamic/static abcd nonsense, with numbers and all. and the dobulge numbers, etc etc. that's it, really. they are the joint parameters' parameters, just like seen in the jp window.
