BIK: Full Body IK Solver

[darkZ]

1. Can we define how far up the chain the IK effects, and how strong the effect is for each bone in the chain? (In your walking example, I would like to have the character lean their upper body forward when climbing a steep slope, and lean backwards when walking down it) And have the pelvis partially shift in height as the knees raise?

• 1. Is there a way to (or plans to) place effectors with precision? (enter exact co-ordinance, world space, or relative to affected bone, or snap to bone-root or bone-tail)
• 1. For the collision support example: will there be a way to interpolate to the new foot position? (to simulate the character lifting their foot up)

1. You should be currently able to define how much the root is effected by the end effectors especially when the effectors get pulled away. This control is something I am refining a bit more for an upcoming update. Leaning backward or forward requires balance control, which I also intend to implement in a future update but not in the next upcoming update.

2. If you look at some of the quick start videos (https://youtu.be/qmQZ0zCwQAA), the effectors can be directly controlled in world space by inputing the coordinates if so desired. There is also plan to parent the effectors so that local control would be easily possible. This should be released relatively soon.

3. There is definitely a plan to implement interpolation, however even better results can be obtained via the smart procedural footstepping for such scenarios if this is what you meant (https://youtu.be/DZU5iP5u8U8) as this allows for a full animation to be used in case the feet are to be planted at a location much further away than their current location as interpolation might not produce desirable results.
