Application Preferences

The “Application Preferences” dialog can be accessed via the pulldown menu (Edit→Preferences). This dialog lets you set application-wide settings across several categories as described below.


These settings are basic, high level options for the Modeler.

Display Scaling

Use this slider to increase the size of GUI components like fonts, icons, buttons, scroll bars, etc. This features is particularly useful when running on high resolution monitors (e.g., 4K monitors on laptops).

Note: The Display Scaling slider is preferable to using the operating system's tools to increase readability/usability.
Warning About Node Edit Losses

Where possible, any operation that may result in the loss of a node edit will be delayed until the user permits it to proceed. This feature is in place to prevent the accidental loss of carefully edited model components.

Use Multiple Processors

When enabled, many of the Modeler's CPU intensive operations (like computing the model) will use all available logical CPUs.

Note: Collision is always performed in a background thread, regardless of this setting.
Always Use Native File Dialogs

Enable this option to bypass the SpeedTree specific open dialog.


The settings in this group control the automatic background saves used for crash recovery.


Controls whether or not autosaving is allowed.

Notify in Console

When enabled, a message will be printed to the console when an autosave occurs.

Interval (min)

Sets how often autosaves happen.

Tree Window

The settings in this group apply to the Tree Window.

Hide Selection Indicator on Edit

When enabled, the selection indication goes away as soon as any edit is made. This feature is to allow you to more easily see the edit but still be able to see what's selected as you pick different parts of the model.

Size of Height Indicator

Sets how tall (in generic units) the human indicator on the height stick is.

Show Fan

Selects when the Fan icon is shown.

The options in this group modify the default mouse control mechanism.

Reverse Panning

Change the direction of pan operations.

Reverse Rotating

Change the direction of rotation operations.

Reverse Zooming

Change the direction of zoom operations (including the mouse wheel).

Control Scheme

Select the scheme used for mouse navigation. Options include “Default”, “Autodesk Maya”, and “Autodesk 3ds Max”.

Property Bar

The options in this group affect the behavior of the Property Bar.

Group Click

Use this property to control what happens when you click a group heading in the property bar. “Reveals” expands the group where it is to show its properties. “Slams to top” moves that group to the top and reveals its properties.

Animate Scrolling

Toggles whether scrolling is animated or instant.

Use Group Stacking

Enables the standard mode where only the properties near the scroll position are revealed. The rest of the property groups are stacked above and below the scroll position for easier navigation. Disabling this mode shows the properties as a static list in each group.


The properties in this group control the graphics quality used when rendering the model in the Tree Window.


When the graphics driver allows application-controlled multi-sampling, use this option to enable/disable the feature and control the quality. Higher settings result in better anti-aliasing.

Note: Multi-sampling must be enabled for the “sample alpha to coverage” (A2C) transparency technique to work. This option applies to all newly created windows (existing windows will be unaffected).
Shadow Anti-Aliasing Samples

The tree window uses depth maps for shadow effects. The edges of these shadows can be softened by sampling the depth map multiple times. Select how many times the depth map is sampled with this parameter. Higher values result in softer edges and slower render times.

Max Texture Resolution

Each material asset has a “Max resolution” setting. For any material using the “Default” setting for this property, this application preference value controls the maximum size of the largest dimension of any texture map loaded for that material.

Lower this value to decrease texture memory usage and increase rendering speed in the window.

Note: Actual exported texture resolutions will not be affected. This preference only governs texture usage inside of the Modeler.
