The 3 basic classes of Baker particles

Baker-Bertrand particles are emitted by compound materials containing Rigid, Tensile, Fuel, Heater and Gas (the Gas is not required in zero-gravity).

The material begins to fracture, breaking into smaller pieces with less spin, and a greater linear speed. The particles also seem to randomly change direction, or stop completely due to Fire Decay and/or Ghostface Killah Deflection. The very last pieces emitted from a block of this material are the fastest moving, but they have no spin. On the contrary, the first particles spin rapidly, but with little to no linear movement.

The existence of the Baker-Bertrand material is due to an apparent glitch in the material TR. Try it yourself, use the Brush tool to create many small pieces of Tensile+Rigid. They will stick together almost magnetically, and without gravity they will start to spin. The smaller the particle the faster it spins.


The strange behaviour of Baker-Bertrand Particles can be attributed to these effects.

There are three normal classes of Baker-Bertrand particles, and then rarer Special Baker particles (the first part of the class denotes rotational speed, the second part denotes linear speed, with α being the lowest value, γ the highest):

  • γ-α - Gamma-alpha (High spin, low linear speed) These are the particles that are made first.
  • β-β - Beta-beta (Mid spin, mid linear speed) As γ-α particles decay, these smaller particles are made
  • α-γ - Alpha-gamma (Low spin, high linear speed) As β-β particles decay, they launch α-γ particles at high speeds. These are the smallest particles, and are made of only 1 point, so they usually don't spin.
