I created my first project in Poser, and I've set limits for all the body parts. Of course I have checked "use limits" on. It works as it is supposed to, but oddly it doesn't work on the IK goal.

So for example, left foot can rotate at any angle ignoring the limit I have set. Turning off IK make it "respect" the limit.

Bug or necessary evil ? :-)

Probably neither, but rather a programmer's choice. By the way, although the goal will not respect the "Use Limits" switch, it will respect forced limits. So if you edit a channel to to use "forceLimits 1" (this can also be done via a pose file), then the limits will be respected, even with IK on.

Thanks. I edited the .cr2 file, and under the right foot actor, I modified code like this:

actor Rfoot:8
    {
   ....
channels
        {
        groups
            {
          ......
            }
rotateZ zRotate
            {
            name TwistRFooty
            initValue 0
            hidden 0
            forceLimits 1
            min -5
            max 5

...

So the right foot should now respect -5 +5 rotation on Z axis. Instead, even with forceLimits on, it still rotates with no constrain.

I have Poser 7.1 Mac.

You are quite right. Sorry for the misinformation. I had noticed that, with limits forced, limits are respected for translations of the feet, and I just assumed that they would also be respected for rotations.

I should realise by now that whenever I assume something about Poser, I will almost certainly be wrong. I just checked, and on my system, P6 under Win2k, limits for the goal actors are respected for translations, whether the limits are forced or just set by the switch in Poser. But, as you say, limits for rotations are not respected. I guess that this does qualify as a bug.

Point At doesn't respect limits, either.

This has annoyed me for years.
