I have a character and he has a knife in his hand. When Run / Walk action happens hands move and so does knife, its collision collides with character's capsule collision and causes issue in movement.

Following is the answer for blueprints

Ignore Knife with reference to Capsule Component

  1. In your character blueprint > event graph draw a new connection from Event BeginPlay node, select Ignore Actor when Moving from list

  2. It has two pins Target and Actor, Set Target to Capsule Component reference

  3. For Actor you kneed to connect the Knife, but Knife is not exactly a true actor, it is a child actor component (A component that spawns an actor when registered, and destroys when unregistered, so do the following)

Get Knife

  1. Don't forget to check should ignore third key

Complete blueprint

that's it, now your Knife will be ignored by your Capsule Component

thanks to @DMGregory for the lead
