You can stop them from hitting the skybox by checking the surface you
hit...look at the HL2 rocket for how to do that. It disappears if it
hits the skybox.
As for displacements, phys objects, etc. your choice of collision group
is almost certainly to blame. I'd use whatever the !picker traceline uses.
