Then uless you're happy fiddling with the scaling in the joint parameters, you might do better trying magnets- in the mgnet properties, select 'add element to deform' and go through adding every body-part that might be affected, and then you won't get sharp differences between the joints. On the limbs, scaling works best with the Y-coord and use magnets for the X and Z coords. Maybe you could try the Ultimate Horse, if you haven't got that already, that's had a lot of good work done on morphing and scaling the Poser horse. Wish I could remember where it's at. Anyone else?
