I have an object that rotates on x and z axis, but will not rotate on the y axis. This is very frustrating as I need it to rotate on the y.
what would cause this? I looked at the parameter limits, they are set at -10000 min and +10000 max.

i do see it will rotate on y using direct manipulation but not the parameter dials.

Look at the CR2 or PP2.  Find the Yrot section for the prop or the Body or whatever
it is you're trying to turn.  See if the line

forceLimits 1

is in that section.  If so, change it to

forceLimits 0

===============

Specifically, you're looking for a section like this:

        rotateY yRotate
            {
            name yrot
            initValue 0
            hidden 0
            forceLimits 1                   <<< ========  If this is 1 or more, make it 0.
            min -100000
            max 100000
            trackingScale 1
            keys
                {
                static  0
                k  0  0
                }
            interpStyleLocked 0
            }

all of the limits are 0 in the pp2

Had you turned it 90 degrees on X or Z first? It's been my experience in that case that you get gimbal lock...irritating ;o).

That's the same quirk that I immediately thought of;  you expressed it so eloquently.  "gimbal lock"  ^^

Have you tried using the Direct Manipulation tool?

Just a thought.

Hehe...that's what it's called ;o)

From Wikipedia:
" Gimbal lock is the loss of one degree of freedom that occurs when the axes of two of the three gimbals are driven into the same place and cannot compensate for rotations around one axis in three dimensional space.

The word lock is misleading: no gimbal is restrained. All three gimbals can still rotate freely about their respective axes of suspension. Nevertheless, because of the parallel orientation of two of the gimbal axes there is no axis available to accommodate rotation along one axis."

Actually, it's only older programs that do this. Most newer 3D programs use a different rotation method.

Hi Geep ..yes, the direct manip tool works...the parameter dial does not.(see post #2).

Rotate xz prior to y .. no ..i tried y right away ...after i couldn't get it to work i loaded a couple more instances of the prop...been experimenting.

but ... i guess its a moot point consideirng direct manuipulation works, but it would be good for a learning experience why the Yrotate dial does nothing.

Hi Dave,

Yup, it's prolly good ol' gimbal lock or ... maybe ...  one of it's close cousins. :lol:

P.S. When you rotate the object using the DM tool, what happens to the parameter dial readings, huh, huh, huh? :huh:

 I Love the DMT! Daveso- NOOOOOOOO!!!! Don't introduce the VUVUZELA to Poser!!!! I can't think straight when that is blasting out of my computer's speakers!! Will we hear it buzzing in the market-or just the discussion board?? "-)

it was loaded into freestuff by Alphonso3d.
my next task is to find a suitable bomb to blow it to smithereens

LOL! You guys are funny!

Oh THANK you Daveso!  A giant War Hammer will also do the trick!

 Hey.. is the thing a smartprop If so that might be why it won't rotate.

It could also be the way it's originally modeled, if the axis is different and it's brought into Poser rotated, you may have gimbal lock and not even know it, then. (I've had that problem with magic wands in the past)

And I think it's a sort of nemesis for even using a Poser Vuvuzela! Those things are cursed!

I thought I posted this before :(  , select the prop and open joint editor. Look at the green center crosshairs and see if they look ok , if they dont then use the align button and see if that fixes it.

I had that trouble when I modelled something and rotated it 90 degrees in poser , could not figure out why it wont rotate properly.

I have heard that the South African Vuvezela Orchestra is getting annoyed with these spontaneous outbreaks of football at all their concerts...
