Can someone tell me what Lock Offsets and Store Rolls does on the constraints dialog?
Lock Offsets allows you to have your hand bone translate and orientlike say a gun bone. When you initially do this, the hand and gun will appear to be intersecting each other. You then move the hand to the position you want (handle and trigger). This is called Offsetting. Now you want to be able to move the the gun and have the hand follow realistically — no slipping. That’s where Lock Offsets comes in. FWIW: With 7.1’s Compensate turned on, you no longer have to set the offsets manually. You position the hand where you want on the gun handle, positioning fingers as desired. Then you select the hand bone, hit the compensate button, then do your Translate To and Orient Like constraints. You will now find that the hand is locked to the gun without the hand moving from your set up. No “Constraint Jumping” (those who’ve had this happen know what this means). Oh yeah, and because these just generate offset channels, the animation is backwards compatible with v7.0. I just tried it. I dunno
