Arc Ik Solver

Post by Hamedss » Sat Mar 30, 2019 10:08 am

Hi everyone.
I wondered how Are Ik Solver work!
I created one bone chain consist of 5 bone with one target and set the chain to arc Solver. But instead of an arc shape I got a ? Shape on these bones!
Is these feature going to work like this?

1) The shape has lots of points for each side. And try to add the same amount to each side.

2) Use a series of pin bones that are parented in a string. In the file use 'Hide/show shy Bones to see all bones.

3) All but the end bone B2 has bone strength. B2 has no bone strength.

4) B2 is the end bone. All but B1 has B2 angle Constraints. I used .1 that are controlled by B2.

5) Turn B2 by holding 'Alt' and moving the mouse sideways.

6) Add a Bone with actions to do #5

Some thoughts, use grid to evenly space each pin bone. Use different bone strength on the shy bones for effects on the curve.

Any questions?

Oh. Really Thanks :shock:
you remember my rigging works in 3ds max :wink:
but let me say that bone chain is a long leg of a character that needs to bend correctly in arc shape. I tried any techniques before but I think Smith Micro need to solve some issue in next version

Perhaps you could simplify the rig, like in this thread

Probably so the shape could overlap itself without creating gaps. If so, there are actually four shapes there.
