Distance Hand Grab building block in Unity

I'm using the new distance hand grab building block with Grab Relative Too Hand set on import to my Unity project.

All works fine for objects close to hand but I need to grab an object further away and it seems to have a very limited distance range function.

The documentation suggests I can change the distance in the SelectrumFustrum function but I'm unable to find where that is.

Can anyone point me in the right direction please.

    For hands, the above steps are very similar except the component you are looking for instead is "Distance Hand Grab Interactor", which should be parented under "Hand and No Controller" game object.

    Hi BwanaSamaki​ ! From your "Distance Grab Interactor" scene component, select "Distant Candidate Computer" -> "Detection Frustums" -> "Selection Frustum" component object. It contains the "Conical Frustum" component which you can adjust properties such as Min/Max Length, Radius Start, and Aperture Degrees. 

    I believe this is exactly what you are looking for - let us know if this helps! 😄

      Aha! Very helpful. Thank you. However I can only find the fustrum on the "Controller and no Hand" element. I've tried duplicating this and adding it to "Hand" and "Hand no Controller" but no luck so far.

      Any suggestions? Here's how my CameraRig building block looks.

    For anyone with this same issue note that I also had to extend the Head Fustrum when using Hands no Controllers
