My question is simple : how do I make a weapon conform to a general model , for example , how do I make the weapon conform if possible to V3 , and P4 woman in the same time. Best regards!

you don't conform weapons to models. You parent them to body parts - most commonly to the hand. A sword, for example, would be parented to vicky's hand. Click on the sword, then open the object > properties menu and go to the far right tab. Under that (not the screen with dials), there is a box that says Set Parent - it opens the hierarchy window where you'd scroll down and select the left or right hand.

also there are smart props - once you parent the item to the hand (or whatever body part or other object you want), save the prop back into the library - it will ask if you want to save as a smart prop, then will give a window to name the prop. Then next time you load that prop into poser from the library it will automatically go to the figure's hand.

As for parenting it to a number of different characters -- simple way is to make one smart-prop for each character. Since the geometry is (should be!) in another file this won't add too much to the total file size. Might also be possible to create SET poses that would move the prop -- but that's getting silly.

Thanks!That was helpfull! Best regards!

I've found that smart props will attach to a different figure if the body-part has the same name, but it doesn't always work well. Remember the detailed posing of the hand (There must be some way of storing that).
