RealFlow provides different channels to visualize specific properties of a fluid. These channels can be displayed in many different ways and dyed: different colours will mimic a certain behaviour or fluid type, e.g. fire or dust.

 

 

Visible

Toggle the emitter's visibility with this checkbox. 

Display type

These are your options:

  • “Point” draws the particles as coloured dots.
  • “Sphere” gives you an impression of what the meshed fluid cloud will look like. Please bear in mind that it takes some time to draw the shaded spheres – especially with large amounts of particles.
  • “Arrow” indicates every particle's velocity and direction. This will help you to identify misbehaving particles. The length of the arrows varies during simulation.

The size of the points, spheres, and arrows is adjusted with the “Size” parameter.

Size

Here you can determine the radius of the points and spheres, and the length of the arrows that are used to represent the fluid particles in the viewport. Values smaller than one are also allowed, but will only affect the spheres.

Particle %

Decide, how many particles you want to see in the viewport. With 10, only 10% of the total number of particles will be displayed, 50 shows 50%, and so on.

Property

With “Property” you can make some of the fluid's channels visible. The range of values for each property will be colour-coded with “Min range” and “Max range”.

Automatic range

By default, the minimum and maximum values are calculated by RealFlow automatically and displayed under “Min | Max range”. The colour gradient is adjusted to this range. With “No” you will be able to define your own range, e.g. for enhancing colour contrast. Particles with values smaller than “Min range” or greater than “Max range” will be displayed with the same gradient colours.

Min range

Here you can see the smallest value of the displayed “Property”. If “Automatic range” is unchecked you can define a custom value. All particles with values smaller than “Min range” will be displayed with the same colour.

Max range

Here you can see the greatest value of the displayed “Property”. If “Automatic range” is unchecked you can define a custom value. All particles with values greater than “Max range” will be displayed with the same colour.

Particle range color

You can define a custom gradient for the representation of the “Min | Max range” values. It is possible to customize the gradient, add additional colours, shift the colours' weights and distribution, and work with RGBA or HSV values: click on “+” for more options.
