Viewport

This is where you can view your simulations, shapes, forces or anything that’s in the scene.

1. Using dragging, you can use this icon to rearrange the UI layout by moving the 4 main sections.

2. Scene is the default tab where you can view and manipulate everything.

5. Dropdown menu of the available cameras. Here, you can select which camera you want to look through.

6. Dropdown menu of all the things that can be hidden or viewed in the Scene tab.

   • Simulation M (15)

   • Unlit Mode U Minimizes the shading complexity. This will significantly speed up the render speed and can be useful when you want better performance when working on your simulation and don’t need to see the final shading.

   • Bounding Box B (14)

   • Shapes H (16)

   • Backplates Shift+B This will toggle the backplate visibility. Backplates can be added in the Camera node.

   • Masking This visualizes all the voxels containing something.

   • Manipulators Shift+Q (17) This toggles the visibility for the transform, rotate, or scale manipulators.

   • Manipulator Switcher This shows the Move (8), Rotate (9), and Scale (10) buttons.

   • Entity Icons (18) show the node icons on the node position. In this case, the Line Force node. Clicking on an entity icon will select the corresponding node.

   • Camera Gizmo (11) Visual representation of the viewport orientation of the active camera. You can click on the dots to orient the view to that axis. Or click and drag the sphere to rotate the view.

   • Render Quality will open a menu to its right where you can pick either Low Ctrl + 1, Medium Ctrl + 2, or High Ctrl + 3

     In certain cases, like when using Flames translucency, you can get a lot of banding when you look up close at your sim. Setting a higher render quality will help to deal with this.

     You can also lower the render quality to gain performance.

     Low, Medium, and High are presets that can be edited in Settings>Preferences…>Viewport Quality

   • Settings (22) Adds a box with common settings for easy accessibility.

     • Render Quality Quickly pick one of the three render quality presets mentioned above.

     • View Mode Pick between using Lit for proper shading, or using Unlit for simple shading to open up some resources for faster simulations. Same as toggling the U key.

     • Projection Quality Cycle through the projection quality presets. This mostly compromises between simulation speed and accuracy of the collisions and pressure. These settings are also in the Simulation node under the Projection tab. For more information about projection please check out our ..TBD.. section!

     • Render Shapes Toggle whether or not shapes are visible. Same as toggling the H key.

     • Lock Camera Lock the active camera so the view can’t be changed anymore. (doesn’t work for the default camera) This is the same as using the Lock checkbox in the General tab of the Camera node.

   • Stats (23)

     • Bounds: The amount of voxels in all three axes. More voxels generally mean larger bounds and more space to simulate volumes. These values can be adjusted using the Voxel count parameter in the Domain tab of the Simulation node.

     • Voxels: The total amount of voxels in the simulation. This is the multiplication of the voxel dimensions mentioned above in mVox which simply means “Million Voxels”. For more information on voxels, please check our voxels section.

     • Sim Time: Time it takes to simulate one simulation step in milliseconds.

     • Sim Speed: Speed at which the Embergen is simulating in million voxels per second.

     • Resolution: The resolution of the viewport in pixels.

     • Render Time: Time it takes to render the volumes to the screen in milliseconds. You can see the numbers lowering when switching to a lower quality or unlit mode.

     • UI Framerate: How many times per second the UI is updated.

     • VRAM: The amount of currently used GPU memory vs total available memory.

     • Particle Count The amount of present particles created by Particles nodes. If it just says 7 it means there are 7 particles in the simulation, 7.0 K means 7000 particles, and 7.0 M means 7.000.000 particles.

7. Toggle panel fullscreen.

12. Sky: These settings are controlled in the Skybox node.

13. Ground: These settings are controlled in the Ground node.

19. Force Gizmo Most foces have a gizmo using light blue arrows showing the direction of the velocity injected by the force.

20. Inner Bound of the selected force. The transparent area of the inner bound shows the area where the force is at 100%. Bounds can be setup by setting the Falloff parameter to anything but None in the General tab of certain force nodes.

21. Outer Bound of the selected force. The darkened area shows the transition area where the force goes from 100% on the inside to 100% minus the Falloff percent (so by default 0%) on the outside.

3. Render is the tab where you can preview what will be exported.

   1. View Dropdown where you can toggle the visibility of the stats.

   2. Render nodes dropdown menu. Here, you can select which Render node you want to preview.

   3. Render passes dropdown menu. Here, you can select which Render pass you want to preview.

Properties Panel

1. Using dragging, you can use this icon to rearrange the UI layout by moving the 4 main sections.

2. Node Details: This tab shows all the parameters for the selected node.

3. Favorites This tab shows all the parameters that are marked as favorites.

   You can do this with any parameter from the Node Details tab by checking the star icon right next to it.

   Clear All will remove all the items from the favorites list. All the star icons will be unchecked.

   In the menubar in Settings/Project Settings… You can also auto-favorite parameters based on the default, the last saved, or a loaded .liquigen file!

4. Timeline: This tab shows all the parameters with keyframe animation enabled.

   Clear All will remove all the items from the list. Note that this will remove all animation!

   Keyframe animation on a parameter is enabled by setting the override state (11) to Timeline Override.

   For more information on animation (timeline) please check out our Keyframe Animation section.

5. Randomized: This tab contains all the parameters with randomization enabled which can be done by Shift + clicking one the override state cycler (11)

   Randomize All Will assign a new random value to all parameters in the Randomized tab.

   The range sliders on the left side define the minimum and maximum between which the random value can be picked. The field right next to this is the parameter value. Will randomize the parameter (instead of all of them). For more information check out our Randomization section!

6. This will open a search box to find the parameter you are looking for regardless of the tab you are in.

7. Only show the parameters with keyframe animation regardless of the tab you are in. This is different from the timeline tab since this only shows animated parameters of the selected node instead of all nodes.

8. This will open a dropdown menu with the options to reset or randomize all parameters of the selected node or tab.

9. Toggle panel fullscreen

10. Parameter tab: All nodes have their collection of parameter tabs sorting the parameters in easy-to-find categories.

11. Parameter tab divider. This visually divides the parameters of a certain tab in the list. You can hide or unhide the parameters of this tab by using the icon.

12. Cycle Override State: Clicking on this will cycle through the different override states for the parameter.

    • No Override: The parameter is only driven by the value put into the field, checkbox, or dropdown menu.

    • Timeline Override: The parameter is driven by the keyframes and can vary over time. For more information please check out our Keyframe Animation section.

    • Pin Override: The parameter is driven by an external node like an oscillator. The value can change over time based on a function. For more information check out our Modulating Parameters section.

    • Randomize Override: Shift + click. The parameter value can be randomized within the range specified in the Randomized tab. For more information check out our Randomization section.

13. Parameter name: Hovering over this will show a description of what the parameter does.

14. Checkbox: This can set a parameter to on or off.

15. Reset to the default value.

16. Mark as favorite: This will make the parameter appear in the favorites tab.

17. Value Slider: You can within this box to type in the value you want. Or and drag to change the value. You can also apply math within these text boxes. For example, typing 4*7/2+6-2 and pressing Enter will put a value of 18 in the parameter. This can be helpful for quickly multiplying a value or reducing it by half for example.

18. This appears when a parameter value outside the default bounds is set by typing it in. Doing this will set the bounds to the new minimum or maximum value. You can click on the icon to open the Set Parameter Bounds window where you can set the minimum or maximum value using the text fields, reset them to the default indicated on the right by clicking on the icon, or reset both using the Reset Bounds button. If the is present it means that the current parameter value is outside of the minimum or maximum bound and resetting that bound will result in the value being overwritten to the minimum or maximum value.

The parameter bounds affect the range of the parameter slider, modulation and timeline controls.

19. Vertical scrollbar. You can use this to scroll through the list of parameters.

20. Horizontal scrollbar.
