- Try to keep track of your cache files. The best way is to create a common folder structure where the Cinema 4D files are stored together with the simulation files. The cache folder can be adjusted under the “Scene” tree's “Cache” tab.
- RealFlow | Cinema 4D writes one particle file per "Fluid" container and frame, and one mesh file per "Mesher" container and frame.
- Both, the number and size of the files can grow quickly, so please make sure that you have enough free disk space available.
- Simulation data are not saved with the Cinema 4D project file. If you close a file without caching all previously simulated data, your results will be lost. The scene elements (emitters, daemons, etc.) will be kept, of course.
RealFlow | Cinema 4D's simulation files can become very large, and this is often seen as something negative. But, the information for 1 or 2 millions of particles have to be saved somewhere. Unfortunately, we're not able to magic away all the position, speed, or density data
