We recommend reading the → “HYM “RKH – Quick Start” Start” chapter for a brief workflow description.

- “Core” ranges between 0 and 1 – it is normalized. A value of 0.0 means that the entire fluid will be seen as the core fluid and you cannot observe any changes in comparison to the original simulation; 1.0 removes all particles. With increasing values the particle cloud will start shrinking, because more and more particles will be removed as they no longer belong to the core fluid.
- “Splash” works exactly the same way as the “Core” parameter. It also ranges between 0 and 1, and with a value of 0.0 all particles are considered splashes. The higher the values, the less particles will be considered splashes – the particle cloud is becoming smaller and smaller.
If you want to learn how to separate a simulation into core fluid and splashes, and how to bring everything together please follow → this link.
Max Velocity
If your simulation contains very fast particles motion blur effects can be falsified or even useless. With “Max. Velocity”, all speed values will be clipped to the given value. An example: Let's assume some particles have a velocity of 100 m/s, while the majority are moving at 20 m/s. In order to get a useable motion blur effect, change “Max Velocity” to 20.

In RealFlow's “Statistics” panel which is available for → → Hybrido domains and → and → SPH emitters. Under “V min/max” you can see the values.
In the “RealFlow RenderKit Particler” node's → “Preview Object” “Preview Object (3DS)", → “Display” “Display (C4D, HOU, MYA, LWV)", or → “RkViewer” “RkViewer (XSI)" panel. The values are displayed under “(Current) Min/Max”).
Wait
You can start the rendering of a fluid sequence while is still being simulated. With “Wait” the render engine will be halted until the next frame becomes available.
