“I don’t see any effect on my skeleton.”

There may be several reasons for this:

  • Check the Output Log for warnings. It could be that the Solver node was not able to find the Character Root, Ground Plane Bone or one of the Effector bones.
  • Check that you have the correct animation blueprint running on your actor.
  • Check that the Power IK Solver has it’s input and output poses plugged in.
  • Check that you are actually telling the effectors to move. By default they are set to Relative to Input Pose with a translation and rotation of zero. This has no effect on your skeleton!

“My character disappears after adding Power IK.”

When using World Space effectors, it’s possible to pull your character very far away from their capsule. Check the values going into the translation channel of the effectors and make sure you aren’t yanking the character back to the origin or to some far off place in space.

Also you make need to put a small delay after Spawn (0.2 seconds) to allow time for your animation systems initialize. If Power IK recieves world space values of zero, it can throw the model back to the world origin, which can cause the LOD system to cull the actor.

“My limbs are bending in the wrong direction.”

Power IK needs a hint of what direction to bend in. If you supply a perfectly straight input pose it may choose a bending angle which “breaks” your character.

You have two options to fix this:

  1. Supply an input pose that has at least some bend in it.
  2. Specify a custom Bend Direction
