Is there a trick to lock a prop to the hands of two figures? Also I have trouble with certain conforming figures like shoes fling off... is there a way to turn them into posable props or something like that so that the origin or whatever is more managable? also... sometimes I have props that will seem to rotate in everyu axis but the one I want... I can't even figure out how that is possible in 3D... I would export/import but for losing morphs. Main question is the first though... thanks

A prop can only be parented to one figure so it is not possible for two figures to ahave a prop locked. It is posible to fix your show problem though. Parent the shoes to the figure of your choice and then save them as a prop. When saving your will be asked if you want to save the shoes as a smart prop... say yes. Next time you use the shoes they will automatically parent themselves to your figure.

You can parent both figures to the prop however. There is a way to set up an IK link that will let you move the prop, and both figures arms. To do this set your scene with the two figures, each with the hand you want touching the prop, posed. Turn IK on for that arm. click on the hand (touching the prop) of one of the figures with the mouse to select it, go to OBJECT>Change Parent and select the prop. Click on the hand of the other figure and do the same. Now when you move the prop, the two figures arms will move.

On your shoe problem. Are you using conforming clothing shoes, single figure for both shoes or each shoe its own figure? Or are these prop shoes?

On the rotate problem. Load a box prop. Position it so that it is sort of center on the figure you want to rotate. Parent the figure/prop you are trying to rotate to the box prop. Can not be a conformed figure, otherwise,okay. Now use the dials on the box to rotate and position the prop/figure as desired. Open the property editor and turn visiblity for box off when done.

By the way, save your file before parenting because it occasionally messes up the pose. It's a good practice to save a lot in Poser because many actions cannot be undone.
