How to Bury Yourself.

Simple steps on how to bury your avatar below ground level.

Rez a cube or a cylinder.

Stretch the prim to its maximum length of 10m.

Right click on the top surface of the prim and select 'Sit here' to sit on the top.

Rotate the prim 180 degrees so that your avatar is facing downwards.

Move the prim downwards into the ground to hide yourself.
You can then move it sideways to 'creep' around without others seeing your avatar.

If the butt end of the prim shows up in certain places, you can change the prim texture to something totally transparent to make it harder to spot.
