AfterBurn 4 supports multiple ThinkingParticles particle groups within the Master System. From the AfterBurn user interface, you can select ThinkingParticles as your source particle, and a new Group selector dialog will appear. Whichever TP particle Groups you pick will be displayed inside the Source Particles/Daemons group of controls (as shown below).
Note: In Thinking Particles, recorded cache (*.tps) does not contain data channels, or they are inaccessible. Therefore, to obtain correct TP data channel output to AfterBurn, for viewport or rendering, you must select SIMULATE and not PLAY in TP Master Dynamic.
