Each RealFlow node has certain display options to visualize the object in the viewports. Particle-style meshes also have a preview function for the individual parameter channels, for example “Velocity” or “Temperature”. It is an easy way to evaluate the results without having to export the mesh to a 3D application.
Visible
You can hide Toggle the mesh from the viewport with this method. To make it visible again, choose "Yes".'s visibility.
Particle channel
When working with channel, it is usually required to preview the results before they are rendered. To activate this feature you can select a particular property and watch the results in the viewport. The last images on the previous page show the particles’ “Velocity” and “Density” magnitudes. It is required to switch to RealFlow’s “Smooth Shaded” mode to make the attributes visible:
Mesh node > View > Element > Smooth Shaded
Transparency
The mesh can be made opaque, semi-transparent or completely transparent. Higher values increase transparency. This option is useful for evaluating mesh quality in combination with the particle cloud’s shape, for example.
Back face culling
When working with high polygon numbers or older hardware it might take a while to display a mesh in the viewport. This process can be accelerated by activating this option, because "Back face culling" does not draw hidden Here you can visualize the active channel from the "Particle Channels" section as a gradient map. To see the channel please activate the “Smooth Shaded” mode with the 0 key.
Transparency
The mesh visibility can range from opaque (0.0) to completely transparent (1.0). This feature does not work when a “Particle channel” is activated.
Back face culling
When enabled RealFlow does not draw hidden mesh polygons.
