A common used mod is "NearClipPlaneAdj", which adjusts the near clipping plane for the player's camera. Without it, if using tiny avatars (we love to be cute you know?) one has a lot of issues using the menu, the view clips inside of ones own arms etc. Also one has issues with getting very close to someone without clipping into that person.
If I remember correctly, it is about the worlds main camera, which dictates how the near clipping plane is set up and if not set at all, they just use the setting of the last map one was into.
Feature request:
  • create a Toggle/Menuentry to adjust the near clipping plane of a player's camera if wished.
