Ok...
So, I've noticed that with certain positions of certain joints - most noteably the shoulder, though occasionaly the hips too - you can get a sort of... uh... "pinched off" joint effect. The model looks fine in Poser, and the pose is technicly correct when you import it, but in SL it looks like the limb is hanging on to the body by a thread. I'm very sure I didn't over-rotate the limb in poser (No 720 degree rotations or anything)... Does anyone know what I'm doing wrong, and more importantly, how to fix it?
See attached image for an example

Its probably the result of two axis of rotation, Rei. Rotating the arm up 90 degrees to point above your head will almost always cause *some* pinching at the shoulder joint... and it can only take a little extra rotation along the arms axis to get the effect in your snapshot. I still havent got around to getting a copy of Poser, so I havent looked at the bone setup for AV's... but I assume they have a shoulder bone - try rotating that bone some, so you dont have to rotate the arm *quite* so much... this will give a smoother displacement of vertex's around the shoulder area and should reduce pinching. Appologies if you already tried this buddy

That's kinda my thought...
But I've been trying to avoid messing with the shoulder bone, because it doesn't seem to translate into SL exactly right. Whenever I rely on it for a pose, my pose always is different in SL than what I had in poser.
Might have to try anyhow.

lol tell me about it, Ive done 12 uploads this week of the same animation and it never fails to generate some random problem, limbs move where I did not even set them to move in poser, others move in completely the opposite direction, to avoid the pinching thing I try to use all avaiable joints to assist the movement, with the one in the pic I would use the collar rotate combined with the shoulder, possibly bring back and tilt the chest too and pull the neck forward

Hello Reitsuki, From: Reitsuki Kojima Does anyone know what I'm doing wrong, and more importantly, how to fix it? Compare your parameters to mine. Varied parameters Left shoulder Y rotation 40 Z rotation 20 Left upper arm Z rotation 0 Left forearm Y rotation 140 Z rotation -25 Left hand X rotation -80 Z rotation 170 It might help you that you should turn on Inverse kinematic when you make a rough motion first. |
