(3) What are all the channels for? A typical joint (the 2nd segment of my flamethrower model's fuel hose) has all these 23 channels which my Poser 3 put in it: twistX tube3_twistx; taperX taper; smoothScaleX tube3_smooX; smoothScaleX tube1_smooX; zOffsetA zOffset; yOffsetA yOffset; xOffsetA xOffset; scale scale; scaleX xScale; scaleY yScale; scaleZ zScale; twistX twistx; rotateX xrot; rotateY yrot; rotateZ zrot; xOffsetB xTranB; yOffsetB yTranB; zOffsetB zTranB; translateX xtran; translateY ytran; translateZ ztran; curve curve - Are all these needed? Which could I delete manually without making my Poser 3 throw a fit? - What is the difference between "translate" and "offsetA" and "offsetB"? Why are all three needed? - Do we need such repeat-in-advance channels as e.g. "tube3_twistx" which merely repeat information which is also in segment tube3's channel "twistx"? - And bulking all this is the endless repetition of such things as "max 100000" and "trackingScale 1" which could be listed as defaults once and for all at the start of the file.
