- Create a scene with a → SPH standard particle emitter and simulate 50 frames.
- Adjust the viewport's point of view.
- Display shelf > OpenGL Preview
- Please make sure that RealFlow exports preview images under Edit | RealFlow > Preferences > Preview > Save Image Sequence
- The preview appears in the → “Movie Player”.
- The preview image sequence can be found in the project folder under preview/video/frames.
- Open “Simulation Retime” from Tools shelf > Simulation Retime
Retiming the Simulation
There is see a stylized timeline in the middle of the window:
...
- In this example the number of frames will be doubled, but this means that playback speed will be halved, because we want to extend the simulation.
- Time factor > 0.5
- A custom time factor can be calculated with this formula:
Time factor = New number of frames / Current number of frames
Previewing the Retimed Simulation
“Simulation Retime” provides two preview methods. The first method is to use the “Timing example” feature:
...
- Press “Try on Movie Player...” and select a frame from the preview sequence.
- The result appears almost immediately, and you have a realistic preview.
Defining Export Resources
The last step is to do the actual retiming. Switch to the “Input/Output Settings” tab, and check if the emitter's export resources are enabled:
