I know this has probably been discussed here before, and I tried some searches, but nothing satisfactory came up. What is up with the big butts when you bend a figure? I know everyone knows what I mean. You;ll take the time to morph V3 into a nice petite girl, and then you bend the buttocks and WHOA! Where did that thing come from?? Time to hit the stairmaster!! I've seen references to Sphereical Bends, same thing happens with the elbows. is there ANY way to minimize this thing? Jeff

Genreally you can get fairly good reults by using the Glutesmall dial and similar for that kind of pose. Also negativ value on pear shape and other 'big hip' morphs may help. Or add your own magnets and tweak. :] Fish

AAAAHHH! Magnets!!!! Thou servant of Evil!!!! ;) I gotcha. Can anyone explain WHY it happens? Thanks!

Simplest explanation is the limitations of the mesh and the way Poser figures are jointed, combined with the way Poser handles geometry. As to the real, actual "why" of it, that's way beyond my scope, but I know that high end packages can cope with this and on much lower poly models, too.

Not to split hairs, but you're contradicting yourself a bit, unless I'm reading into this wrong. You say it's a limitation of the mesh, but also that high end packages (meaning software, I assume) can cope with it. So it's not the mesh, but Poser. That's what I'm hearing.... Sorry to seem contrary.. Jeff

Its from sitting in front of the computer all day and night playing with poser figures instead of getting a life and... Oh, you mean the poser figures bending over. Sorry.

Part of the problem is the way the spine-hip joint is constructed in most Poser figuresall of them are swaybacked! You can correct this by bending the figure forward at the waist about 5 or less, rotating the whole figure back to vertical, and then bending the legs back to vertical. This flattens the curve of the lower spine (and incidentally, rotates the hips into the proper position for good upright posture. Bending the figure at the waist now produces a proper spinal curve and the big glute problem is lessened. You still have to do some work, but it's much easier from that point.

Triarius, I don't suppose you'd have a pose file for that, would you? :-)

Ugh! I did, a long time ago, before several reinstallations. I'll dig around and see if I can find it. Not hard to do, if you don't want to wait for my archeaological expedition. Just remember to turn IK off on everything, and that all Poser figures rotate around the hip.

Just for clarification, Triarius, since there is no waist object, do you mean the hip or the abdomen?


PabloS posted Tue, 15 June 2004 at 6:54 PM

Triarius, I'm kind of confused too. Let me see if I got this straight. Starting from a zeroed pose: - bend Abdomen(?) forward 5 degrees (or less) - bend Hip (Body?) back to vertical (probably the same number of degrees that the Abdomen was moved forward) - then bend legs (Buttock or Thigh?) to vertical
