Is there a way to enlarge the bounding volume on a Mesh (or Spatial) in order to increase “tolerance” for picking? I have some small objects that would be a pain to click directly, so I want a collision to occur whenever the click is somewhat close. I tried something like:
Picking is done on the mesh level, not on the bounding box.
the bounding box is used for culling, so I recommend you leave it as it is.
For your issue, the quick and dirty solution would be to have an invisible bigger box surrounding your object and following it.
attach your geom to a node , attach the box to this node too place it so that it surrounds your geometry, and set the box cullhint to always so that it’s never rendered.
Else, maybe shooting several rays around the mouse position could get you more chance to hit the geometry, That’s not 100% guaranteed but It would be less dirty than the ghost box.
