These settings let you store collision details from your scene, and enable and
disable collision detection for specific pairs of objects. Pairs of objects with
collisions disabled pass through each other during the simulation. Disabling
collisions can be useful when you have objects that are attached together,
such as the wheels of a car and its chassis. This means reactor doesn't check
for every small collision between the objects, which can slow down the
simulation.

Pairs of objects with disabled collisions pass through each other during the
simulation.
Selected Pair: Enable Lets you quickly enable collisions between the selected
pair of objects. This button is available only when both objects are part of a
collection (not necessarily the same collection) and their collisions are currently
disabled.
