    [VIVE] Operating Room equipment boom movement setup

    I'm creating an operating room in VR and I want to be able to grab the end of the light boom with the motion controller to move the light with the arms of the boom constrained and moving appropriately.

    What is the best way to set this up? All the tutorials I can find deal with making character rigs or simple pivot doors that react to a physics push or trigger.

    I think it's a two part question of how do I rig the boom (bones from 3DS Max, skeletal mesh, physics constraints, etc) and then secondly, how do I set up the Blueprint interaction to grab the boom to move it.

    I'm using the VR template and I'm guessing the AttachTo setup they have will not work for this. I'll be happy to be wrong.

    Hi ColinD97,

    This loos like a rather complex model. Are you familiar with rigging? If not, try to rig something simple first, like a simple handle or desk lamp.

    You should also try to implement the grabbing and moving part with a simpler model to fully understand how the process works. If you got this, you can try and go on with your OR boom.

      You can definitely rig the OR boom with few bones, then grab the handle and use inverse kinematic (FABRIK node) to adjust its configuration accordingly. Note that you may have to modify the way you grab the handle. Instead of attaching it to the hand (AttachComponent) like it is done in the standard VR template, just have the boom "track" the hand position as long as it is being grabbed by it.

        Marco - Anyway to elaborate? I can't seem to figure out what you mean by "track."

        Thanks!

          By track I mean "follow". So the boom monitors where the hand is and follows it.
