How does it work? I can find the button on the left of the work area ( and turn it on ) , but it doesn't seam to do anything. If somebody knows.... Peevee

if you read the manual well youll see that you need to enable collision detection for every object you want it to effect.(do this in the properties tab) secondly, you wont see any reaction if the objects are keyed to intersect eachother. itll only work if they inadvertently collide, as the resuly of gravity, another expression(python script i think its called). i messed around with it for a while and figured it out, but then never used it in anything, so i kinda forgot. but its more complicated than it needs to be, i think..... ganbatte!!!

So basicly it won't help me if I try to prevent a figure intersecting itself? ( like a hand disappearing in a hip or something like that )

first turn on the figure s collision detection in the properties tab,(from the hip) then click apply collision settings to children. then select the right hand(sorry, before you select it enable ik for the right or left hand, whatever you select) now turn on collision detection for the document window, and use the parameter dials to move the hand in towards the body(use xtrans dial, and side to side dial cause youll break her wrist...)and youll see that the hand still passes throgh the body. now move it away again and select the translate/pull tool in editing tools bar, and if you use that it will collide with the body and not move through. but i find using the dials easier so it doesnt do me a lot of good. i dont find collision detection to be all that useful, but i only do limited things in poser to use it like you said, make sure all the collision detection things are on, and use the editing tools to make your pose, not the dials

"then select the right hand(sorry, before you select it enable ik for the right or left hand, whatever you select)" What does "ik" mean?

inverse kinematics, it is a way of animating things so that you move one part and the rest follow, instead of moving each part seperately.

use inverse kinematics is in the figure menu in poser 5.
