Subject: Body centring problem

I've just created a posable striped tie which is destined for Free Stuff but I have a problem. It all works fine except that when I select 'body' and then use xrotate it rotates about a point about two feet in front of it. The joint editor will let me adjust the centre of rotation for individual parts but not for the figure as a whole. How do I fix this? Here's a picture of it, though it doesn't show the problem. Maz

Select the body and open the joint editor. You should be able to adjust the center point numerically.


Maz ( ) posted Thu, 28 December 2000 at 6:43 PM

I think I've tried that but without success. When the body is selected I didn't get the red or green cross hairs so couldn't move the centre. When individuasl parts are selected it worked OK though. Maybe it's me, I'll have another go.

Had another try but just succeded in messing things up completely. Is it possible to do it by editing the cr2 file?


JeffH ( ) posted Fri, 29 December 2000 at 8:44 AM

I'm not sure about the CR2. When you open the joint editor there are three boxes for numerical imput. Copy what you see there so you can restore it if needed, then change the numbers until you have the center point you want. I don't know of another way to do it right now. Send me the file and I'll give it a go myself if you like. howarths@bellatlantic.net -JH.

Yes. But it's a lot harder because you won't know what numbers to put there. The Body Center point is very flakey and usually hard to find for any custom character. The way I find it is to select the body. Then rotate it with the dials to get an idea where the axis is. Once you know approx. Where it is. You can type in a new number in the proper field in the joint editor. Then test it again. It shouldn't take very long. Once you know approx. where it is. ScottA

Hi Maz!- Is this a conforming tie? If it is conforming, the base part (the part that is parented to BODY in the CR2) should normally have the same numbers in Joint editor as the same part of the figure it is conforming to, for x y and z. I alway just use a existing CR2, I never (well hardly ever) do it from scratch.

Thanks for all the advice guys, but I'm still not making any progress so I'm taking Jeff up on his offer and the files are on their way to him. I certainly agree with ScottA that it's hard. Also, the manual seems very vague in this area. Jim, not it's not a conforming tie. I have enough trouble with bog standard posable figures. When I've got them licked I'll have a go at making them conform too. :-)

Maz, I wasn't able to change the body Center, but that no matter. The main problem was the center point of the "Knot". That's the "hip" of the figure and you should be able to rotate and position it successfully with that. Here's the fix: Select the knot and open the joint editor. For the Center point change the numbers in the three boxes to this 0.000 0.010 0.235 After that use the knot to position the tie. Hope that helps. -JH.

Thanks Jeff, I'll do that. It bothers me though, that Poser arbitrarily shifts the body centre like this. Why does it do it? When I created the figure I made sure it was centred properly about 0,0,0. If you load the obj file as a prop it comes in perfectly centred, so why does it shift when it's converted to a figure? I'm sure there must be something in the cr2 that defines the body centre but I guess it would take the best part of a year's experimentation to discover it!

It may have to do with the rotation orders, but I can't be sure. Probably something simple that we're overlooking, it always is ;-)
