| Some parameters and channels are available in RealFlow | Cinema 4D 2.5 and will be released soon. |
RealFlow | Cinema 4D particles are differently coloured according to their velocity, vorticity (has to be activated separately under → Fluid > Fluid > Compute Vorticity), or age values. These values can be transferred to meshes and rendered, adding some extra realism.
Blue colours indicate low values, brighter tones stand for higher channel values.
Vertex Maps
When you take a look at the "Mesher" object you will recognize several "Vertex Maps" tags representing the fluid's channels: speed, vorticity, age, weights, velocity X|Y|Z
...
- If you want to use vorticity you have to activate → Fluid > Fluid > Compute Vorticity before the simulation, otherwise the channel will not be available.
- The "Weight" channel is makes only senses if the simulations contains at least two emitters or fluid containers, and requires a slightly different → workflow.
- The "velocity X|Y|Z" vertex maps cannot be adjusted manually, and they are required for motion blur effects.
The complete selection of channels with the "Smoothing Length Scale" value to blend materials.
...
"Smoothing Scale Length" ranges between 0 and 1 (0 = no smoothing, 10 = maximum) and helps to avoid flicker and improve the transition between the colours/materials.:
- When "Smoothing Scale Length" is being changed the meshes have to be rebuilt or recached!
