Ahhh SHOOT - Thats a DarkPhysics DEMO - I GOOFED.... To Many Forums so little time hahha ... Seriously - Sorry.
Um... I think I know YOUR problem.
First Off - There are two ways to do it - Offset or As Is.
Offset - you add limb - then Offset it.
As Is - the TRICK HERE is to Put your OBJECT at position 0,0,0 NOT Rotated and THEN Position The 2nd Object where you Want it - Then ADD the limb. Now you can move the object and the limb will follow.
Experiment - as there are reasons one may choose to do either way.
ALSO - VanB and soem other local gurus have said in the past that sometimes the ORDER you add limbs can effect stuff - so if it acts weird remember that the order you add the LIMBS MIGHT Hose ya! depends on what you're doing because I haven't seen that problem yet - but like I said - reliable sources say - "Careful" "Be-Aware"
Sorry about machine demo mix up... There are linked joints in Dark Physics.... Nonmenclature spillover
