I think reverseFoot component may not work well with fkikBlend.
For example,use electra rig in content library.(https://www.sidefx.com/contentlibrary/electra-rig/)
Reset all in sceneAnimate,switch to fk with "L_Limb_abst".
Rotate "calf_l_fk" and the leg moves,but the toe still pointing towards front,and it's not rotating with "ball_l_fk" contorl.
Back to ik,everything works.
I checked rig logic,it seems toe joint is drivn by some "lookat constraint stuff".
That seems to work in ik with reverseFoot,not with fk.
Btw,I do tried to change orders of autorig like:multiik---reversefoot---fkikblend,and the result is good fk and bad ik.(unable to use ik toe/ball control)
So it's a little bug or some wrong setup maybe?
