Mist - Display

Mist emitters offer a variety of settings to visualize the density field at different quality levels. A “highlight” is a mist node’s capability to show a daemon’s force field. This can be achieved with “Show velocity field”. A description of how to achieve this effect is added to the parameter's description.

Visible

This switch is used to show or hide the grid mist emitter domain and its content.

Domain

You can choose from three different modes: “Box” is the default setting and represents the area of your scene where the mist is computed. Small boxes at the corners indicate the resolution of the mist. The “Points” option shows a point at the cells positions, giving you an idea of resolution and the places where mist is computed. If you do not want to show any representation of mist in your viewports, select “None”.

Quality

Displaying and updating the emitter’s density field in your viewports is computationally intensive if you have a high resolution mist. Additionally, there are some graphics cards with strong memory restrictions being unable to show the mist at original resolution. For that reason you can select the quality of the mist field’s representation. Please note that this parameter only affects the visual representation and of course the internal resolution/quality is computed physically correctly. On the other hand, high-quality settings increase simulation times.

Show velocity field

For evaluation and shading purposes it is often necessary to visualize the mist’s velocity vector field. With this option it is also possible to visualize a daemon’s force field. You can switch this feature on and off by choosing “Yes” or “No”. Please follow the these steps to make a velocity field visible: 

• Add a daemon of choice and a mist node to your scene.
• Set the mist node’s “Bounded” option to “Yes” and rescale the domain, if necessary.
• Activate “Show velocity field”.
• Simulate the scene.
