phys_bone_follower

phys_bone_follower is a point entity available in all Source games. All props that use a model with $collisionjoints will generate these. One bone follower is created for every convex piece of its collision model. These can quickly eat up the entity count! Enabling the "Disable Bone Followers" keyvalue on the prop will disable bone followers, although the prop will no longer have a functioning collision model, and the model will not be able to ragdoll. The .phy of a model can also be deleted to remove the collision model and save file space, though this will affect all instances of that model.

 Note: Despite common misconception, models which only use a $collisionmodel do not create phys_bone_followers.

An example of phys_bone_followers on a complex model. 15 phys_bone_followers are created for each convex piece of the collision model, resulting in 16 entities! The IN represents the server traffic, a staggering amount for 1 model.
