One thing you should note: 1. If you create pre-simulated fluids (for example you fill a pool with particles to create splash effects), the particles retain their original ages. So if you then use initial states for your pools, keep in mind that the age of the particles isn't zero at that initial state, but whatever age the particle was before you created that initial state .bin file. So lets say it takes 1,000 frames to create your pool initial state. You then reset to initial state and simulate for 100 more frames. If you then try to load the particles inside C4d/TP, the age parameter for the TP node must be set to 1,100 -- not just 100. If you set it to only 100 because that's how many frames your splash simulation was, the particles won't load, because they're really 1,000 frames "old" at frame zero, so the RF node simply deletes them.
