RealFlow also supports a textured view and draws an object’s texture based on its UV coordinates.
"Show" Submenu
This menu contains a list with all of RealFlow's node types and you can choose which elements you want to display or hide in the viewport simply by checking or unchecking the desired entries.
Grid
To hide or show the viewport grid, please choose this option.
RealFlow Nodes
By default all available node types are visible in the viewport. Uncheck an entry to hide a node type.
Selection Highlighting
When a node or scene element is selected it is highlighted and displayed with a bright green colour to separate it from the other nodes. In some cases, this highlight effect is not desired and can be confusing. A very good example where “Selection Highlighting” will be switched off is most probably (interactive) meshing: when a mesh is not highlighted you will have a much better view of its polygon structure. It will also be easier to evaluate its quality and recognize subtle changes during the meshing process.
"Point of View" Submenu
You can change the current viewport view to “Top View”, “Front view”, “Side View”, “Perspective View”, and "Camera View". If you want to use a camera (“look through it”), it is also possible to drag the camera node from the “Nodes” panel to the viewport. Then, the perspective will be changed to the camera's view.
