Has anyone else had problems with the preloaded examples of IK in 3ds4? i.e. Stairs.3ds, Climb.3ds, etc. I' m linking the appropriate hands and feet to their moving dummy objects, but what I end up with is the figure's body remaining stationary and the four limbs "reaching out" towards the dummys as they follow their course. Shouldn't there be a dummy for the body to follow? Maybe I haven't completely grasped the IK thing yet. Help-

You want to animate the body first, slowly moving up in front of the ladder, "floating" up with the hand and foot dummies. Then do the IK follows. It is in the tutorial, I think. – Ron

Ron- Thanks for the advice. My problem is that when I was designating the chain in IK I was placing the start point too high up the hierarchy.(i.e. picking torso for the start of the hierarchy instead of just the top part of a leg.) It's working fine now.

Hi Bruce, << Maybe I haven't completely grasped the IK thing yet. >> Please download and review the readme and the *.prj in the following file.. File Info for FLIP.ZIP Section: Mesh/Project Files Contributor: 73172,1351 Size: 95951 Submitted: 10/21/94 Type: Binary Accesses: 15 Title: IK Backflip Keys: IK FLIP R4 This is an example of using IK a number of different ways. A woman doing a 1 1/2 back flip off of a diving board. There was no keyframing of the board or the woman on my part. All movement solved for by using IK. This zip includes a solved version and an unsolved version so that the R3 users can compare the two files. Note also the flip.zip (a flip.fli) in the Animations section of the lib. IK'd and uploaded by jonas.
