I have a Character mesh. i create a skeleton, connect it to 'Rig Stash Pose'. i weight paint using 'joint capture biharmonic'. i tweak each joint weights precisely using 'capture layer paint'. then, i temporarily setup kinefx (connect everything to 'bonedeform' and 'rig pose' nodes). Then i create a 5 frame Animation (like a finger curl). then i delete 'bonedeform' and 'rig pose' nodes. then I copy each frame's pose into a new 'rig pose' node. Now i basically have a 5 frame Animation SEQUENCE, but each pose is stored in a 'rig pose' node. Then Each rig pose node is connected to its corresponding 'name' node. then each name node is connected to 'pack' node.

Now i connect everything to 'pack folder'.

In the attributes of 'pack folder':
==================================
The Character is setup as '.shp'; the main skeleton is setup as '.skel'. All Additional 'pack' nodes are setup as '.skel' as well.

Then i initialize apex by adding an 'apex auto rig component', in attributes, i pick 'FK transform'.

then i connect another 'apex auto rig component', in attributes, this time, i pick 'bone deform'

Now i connect 'apex graph' or 'apex edit graph' to 'bone deform'.

inside 'apex graph'(accessed via apex's network view):
how to setup Blender's ACTION CONSTRAINT with 'Skeleton Blend' so that a "Clamped Slider" can drive a sequence of 'rig pose' nodes?

Some people say that, in Apex graph, 'pose blend' / 'Sop::blendshapes' / 'Character Blend Shapes Add' nodes can be used to achieve this. i dont how either.

However i want to do achieve this with 'sop::kinefx::skeletonblend'; after all i'm using same mesh....same rig skeleton...same joint names, but posing diff poses in unique 'rig pose' nodes.

We know that 'skeleton blend' can drive: T-pose to pose A; T-pose to pose B, etc....
= I dont want that.

I wanna drive an Animation frame sequence from T-pose,
i.e using an Abstract Control (driver) to drive T-pose to pose A,B,C,,,,etc.

i dont know Apex script. i'm a beginner who doesnt know programming. Hope some kind soul explains how to achieve this via 'apex graph'.

Thanks a lot to 'The Great' William Harley and 'max rose' for wonderful tutorials on APEX. Thanks.

oh! btw, i've also attached my failed attempt hip file. I've tried to ask chatgpt and gemini many many many many times about houdini's Apex graph. but failed. any way here's what i got till now.
