Max Binds p/Particle - The greatest number of binding candidates that the software considers for each particle, within the Bind Distance. This can affect the particle arrangement after binding; you might want to experiment with it to find the best value for your simulation.

When To Bind With group > Deflectors and/or Ground binding options are on (see following), this limit is ignored in defining whether a particle can be bound to a deflector and/or the ground. In this sense, bindings to deflectors and the ground have a higher priority than regular particle bindings. However, if a particle binds to a deflector and/or the ground, these "VIP" bindings are counted as a part of the total number of bindings for a particle, so it can restrict the number of particles a particle can bind to.

Tip: Allowing a large number of bindings for a particle makes the simulation more complex and potentially unstable because more counter-forces are applied to a particle. For optimal stability and accuracy in simulations that use bindings, it's recommended that you increase the Subframe Factor setting in PhysX World helper. A good general formula is [Subframe Factor] = 2 * [Max Binds p/Particle] + 2. So if Max Binds p/Particle is set to 4, then set Subframe Factor to 10 (2*4 + 2).
