Hi Andrew, << I have been working with IK alot in the past couple of weeks and I have ran into an odd problem. Sometimes when linking objects and then going into IK I get an invalid chain, eventhough it is a valid one. Then I can isolate the peticular part of the chain that is the problem, go into the editor, make a copy of the object, delete the old one, and then use the new one in the chain and then there is no problem. This seems strange to me, especially since, in one instance, all the part of the chain were copies of each other. Then in a slightly similar problem, I can create a heirarchy, and then go into IK and set everything up correctly and everything works fine. But if I than go back out to the 3D editor and adjust mapping parameters or add parameters to an object, when I go back into IK I get an invalid chain. >> I'd like to get a copy of the problem file and a detailed step by step description which allows me to consistantly recreate the situation. jonas[adesk]
