PRT FumeFX Objects Explorer¶

Available in Krakatoa v1.6.0 and higher

Overview ¶

In Krakatoa v1.6.0, the rendering of Sitni Sati’s FumeFX simulations requires a dedicated PRT FumeFX Object to be created to turn the voxel grid of the fluid simulation into a particle cloud (in v1.5.x, the simulation grid was rendered directly).
The PRT FumeFX Objects rollout in the Krakatoa Explorers floater can be used to create, overview, select, hide, unhide and mass-modify the settings of the PRT FumeFX objects in the scene.

When checked (default), the list selection and the scene selection will be synchronized automatically in both directions - selecting PRT FumeFX objects in the scene will update the objects highlights in the list and highlighting objects on the list will select them in the scene.
When unchecked, the scene and list selections will be decoupled and will not be updated (this is especially useful when working with heavy scenes with many objects).

This list provides various display categories.
- All of them list the name of the PRT FumeFX object in [] brackets, prefixed by its unhidden/hidden state (+ or –), followed by the specific information selected from the list:
The following display categories are available:
- FumeFX Source - shows the name of the volume source object and the FumeFX simulation it derives data from.
- Fire/Smoke Seeding - shows the state and the “Min. Threshold” values of the “Seed in Smoke” and “Seed in Fire” options.
- Region Seeding - shows the states and value settings of the “Subdivide Region”, “Jitter Position” and “Multiple Per Region” options.
- Random Seed Settings - shows the “Distinct Values” and “Seed” values.
- Viewport - shows the Viewport settings including “Enabled in Viewport”, “Disable Subdivisions”, “Percentage”, “Limit” and “Ignore Material”
- Miscellaneous - shows the “Disable Velocity”, “Generate Emission from Fire” and “Generate Normals…” options.
- Test Renderable State - shows the renderable state of the object.

This button has the same functionality as the PRT FumeFX MacroScript in the Krakatoa Menu and toolbar.
When pressed, if there are FumeFX simulation objects selected in the scene, a PRT FumeFX will be created for each one of them.
If there are no valid selected objects, a PRT FumeFX will be created at the world origin.
If the SHIFT key is pressed while clicking, the Command Panel will enter PRT FumeFX creation mode.

The listbox shows the information about the PRT FumeFX objects in the scene.
Each line represents an object, starting with a + or – sign to denote the visible/hidden state of the object, followed by its name and more information based on the Display Info drop-down list (see above).
Selecting items on the list will select them in the scene if >Synch. Selection is checked.
All mass-changing controls described further on this page will operate on the objects highlighted on the list.
The list supports multi-selection using the Ctrl and SHIFT keys like in any Windows application - hold down Ctrl and click to add/remove from the selection, or hold SHIFT and click to select a range between the last click and the current one.

Pressing this button will deselect the selected objects on the list and vice-versa.
If >Synch. Selection is checked, this will also update the scene selection.

Pressing this button will hide in the scene all objects highlighted on the list.
The prefix symbol on the list will change from + to –

Pressing this button will unhide in the scene all objects highlighted on the list.
The prefix symbol on the list will change from – to +

Pressing this button will highlight all hidden objects, thus making it easier to unhide them or perform other operations.
To select all unhidden objects, simply press this button followed by the Invert Objects Selection button.

The controls in this group can be used to modify base object settings in multiple highlighted PRT FumeFX objects at once.
These settings are always assigned by the press of a button - the spinners are not directly affecting the highlighted objects but require the pressing of the Set Value button to do so.
Similarly, for changing the checkbox properties between checked and unchecked, you habe to press the …ON or …OFF button corresponding to the respective property.
