Is there a way in the FK chain module when switched to IK mode (spline) to control the twist not on the whole length of IK (e.g. tail/snake), but in the middle of the chain (not on exact middle, I mean somewhere on the length of a chain, in multiple places), ideally with each IK controller (crtl shape)?
I haven't found a way to do so apart from abovementioned whole twist by rotating the last IK ctrl. Animating e.g. snakes gets tricky without the advanced control over twist.
OK, great! That's fantastic news for me! Thank you very much for quick reaction, I will test it out soon :)
As of rrm3_installers_BETA_2023_07_15 there is a new "autoTwistJoint" attribute on each IK control for FK chains.
If "autoTwistJoint" is set to 1, it will have the existing behaviour where the twist is automatically driven as a ratio between the start and end.
If "autoTwistJoint" is set to 0, it will take the upward orientation of the IK control. Notice the difference of the Y-axis between the two images.
Note that in some poses there may be flipping when transitioning between 0 and 1 with the autoTwistJoint, so you will just have to be careful.
