I made a "stupid" workaround by deleting the stem prim, so my horizontal lines are not parented. However, I don’t know how to rotate in KineFX without this parent relationship, so I wouldn’t have to delete part of my rig.
Full Version: Rotating with parent compensation - KineFX
Hey, I made rig like this and Im wondering how to apply twist rotation but without this "inherited twist". I dont know how to describe this in words. I want to twist without affecting previous bend direction.

It's not clear to me what you're trying to accomplish. Rotating @localtransform will rotate the pre-existing local transform relative to its parent. If you don't want that, then I think will need to multiply the rotation with parent's inverse world transform.
use world space transform instead of local altogether
float mask = fit( f@curveu, chf("min_u"), chf("max_u"), 0, 1 ); mask = chramp( "u_ramp", mask ); float angle = fit01( mask, chf("min_angle"), chf("max_angle") ); prerotate( 3@transform, radians( angle ), {0,0,1} );
