To use an initial state with a simulation it is not enough to activate “Use InitialState” – you also have to reset to this specific point. This can be done by tagging the “Reset ToInitialState” option next to the "Reset" button. With the next reset, RealFlow will load the initial state file and the simulation starts from 0 again. Existing cache files will be overwritten with a new simulation. Normally it is not necessary to backup previously generated files, but if you need them, do not forget to change the appropriate export resource.
Here is the workflow:
- Make an initial state with the “Make Initial State” button.
- Set “Use Initial State” to “Yes”.
- Activate the “Reset ToInitialState” option next to the “Reset” button.
- Optional: Backup your previous data or apply a new export name for the emitter.
- Reset the scene to load the initial state at frame 0 (or any other specified frame).Simulate, using the initial state.
