3DS MAX: anchor last segment of an IK chain at a FIXED point in space (ie. world coordinate).
Hi, the objective is that:
1. arm made up of two IK chain: arm chain and hand chain
2. hand chain will need to:
a. be attached to arm chain and when arm rotates or moved, hand chain need to move along
b. sometimes, last segment of hand chain need to be positioned at a FIXED point in space (relative to world cordinate - not shoulder)
Problem:
Last segment of hand chain just "points towards" - not actually touching/overlapping - the goal of hand chain (goal is fixed in space).
Attempt:
I tried linking goal with last segment of hand chain - that doesn't work: last segment of hand chain will detach from the rest of the hand chain.
Thanks!
PS: I can send you the MAX file, or simply a JPG (too big to upload here)
