Paint

Disable Paint Undo

Turns off the Edit > Undo feature when painting (and only for painting) to improve interactive performance.

Color

Specifies the default colors in the user interface. Click a colored rectangle to display the Paint Tool Color window then modify the default color settings for the item.

Render

Limit Wireframe to Level

Specifies the highest subdivision level that the Wireframe display option will update on a model. Setting this number to a lower value aids in improving the interactive performance when working with complex models. For more information, see Change the model display.

Max Texture Size

Specifies the size limit in pixels that a texture image can be displayed in order to save memory usage. Textures larger than the specified resolution are reduced to fit.

Fast Render Scale

Increases the interactive performance when tumbling dense models in the range of 4 million quads and higher). If you want your model to look as detailed as possible and are not concerned about performance, set Fast Render Scale to a value of 0.1. Higher values in the range of 1.0 - 2.0 allow the model to tumble much faster but fine detail appears when you zoom in very close.

Level change tolerance

A surface sampling sensitivity setting for Fast Render Scale. A low value (0.7) indicates more surface sampling, while a higher value (3) samples the surface less often. The default setting is sufficient in most situations.

Use Texture Filtering

Mudbox applies an anti-aliasing filter to smooth the appearance of any textures painted or applied to a model. The default setting is on. If you need to view textures without this filtering applied turn this preference off. Turning off this preference can also improve performance for the Ambient Occlusion viewport filter on older graphics cards.

Files

Small File Size

Compresses saved files resulting in smaller file sizes on disk. File > Open operations will be longer on files saved using this option.

Generate thumbnails when saving Obj files

Specifies that a small bitmap image of the 3D View is created whenever a file is saved. This image is subsequently displayed in the Open a file area of the Welcome window to easily identify it.

Preprocessing face count upper limit

Imported quad models undergo a pre-processing phase when loaded into the 3D View. This setting sets the upper limit for determining the range if a model is pre-processed or not. A model with pre-processing will tumble much faster when its polygon count dense (4-100million polygons).

Preprocessing face count lower limit

Imported quad models undergo a pre-processing phase when loaded into the 3D View. This setting sets the lower threshold limit for determining the range if a model is pre-processed or not. A model with pre-processing will tumble much faster when its polygon count is dense (4-100 million polygons).

Enable Preprocessing on Load

Imported quad models undergo a pre-processing phase when loaded into the 3D View. A model with pre-processing will tumble much faster when its polygon count is dense (4-100 million polygons). Upper and lower face count limits can be specified. Pre-processed models will not preserve the original vertex IDs.

User Interface

Linear Units

Sets the measurement units for the world. Options are: millimeter, centimeter, meter, inch.

Double Click

Sets the time limit in milliseconds that distinguishes a double click from two consecutive mouse clicks.

Drag Box Size

Sets the distance (in pixels) that the cursor must be within in order to select a control point when editing the brush profile within the Brush Falloff properties.

Show Learning Movies in Welcome Screen

Specifies whether the learning movies appear in the Welcome window whenever its displayed. When turned off, the Welcome window appears with only the Start a new sculpture and the Open a file options displayed.

Show Informative Messages on HUD

Specifies whether the Heads-Up Display (HUD) that indicates status (current subdivision level, polygon count) for the active model is displayed in the 3D View.

Show Welcome Dialog

Specifies whether the Welcome window that gets displayed for the one minute movies and file open operations is displayed in the 3D View by default.

Show Help Messages on HUD

Specifies whether the Heads-Up Display (HUD) that provides useful tool tips (hotkeys and feature usage) for some features are displayed in the 3D View.

Get Help From

Specifies where the Mudbox Help is accessed from whenever Help > Mudbox Help is selected:

• Autodesk Web Site - The Mudbox Help is accessed directly from an Autodesk web server. This is the default setting and provides the most current version of the Mudbox Help.
• Local Machine/Network - The Mudbox Help is accessed directly from your local computer (or internal network location) depending on where the Mudbox Help has been manually installed. Use this option if your internet access is unreliable or if you’re working in an environment that doesn’t normally provide or allow internet access. You must first install the Mudbox Help on your computer (available off the Documentation page of the Mudbox Learning Resources web site) then set the Help Path option in Mudbox. For more information, see Install the Mudbox Help on your computer.

Expert Mode Hides

Specifies which elements of the user interface are hidden/displayed whenever the T hotkey is pressed:

• Status Bar - controls the display of the Status Bar at the bottom of the user interface.
• Menu Bar - controls the display of the menu bar at the top of the user interface.
• South Frame - controls the display of the brush and stencil trays at the bottom of the user interface.
• East Frame - controls the display of the managers and properties windows at the right side of the user interface.

Tool

Texture Ratio

Specifies the stamp texture size relative to the painted texture. The larger the ratio, the better paint quality can be achieved but the paint brush will be slower as a result. Options include: Fast, Full, and Medium.

Paths

Stamps

Specifies the directory location for stamp files. Click ... to specify a new directory location.

Stencils

Specifies the directory location for stencil files. Click ... to specify a new directory location.

Icons

Specifies the directory location for image icon files. Click ... to specify a new directory location.

Image Planes

Specifies the directory location for image plane files. Click ... to specify a new directory location.

Log Files

Specifies the directory location for log files. Click ... to specify a new directory location.

Temp Files

Specifies the directory location for temporary files. Click ... to specify a new directory location.

Settings Files

Specifies the directory location for settings/preferences files. Click ... to specify a new directory location.

Data

Specifies the directory location for data (.mud) files. Click ... to specify a new directory location.

Textures

Specifies the directory location for paint/texture files. Click ... to specify a new directory location.

Focus

Dolly With Focus

Allows the camera to dolly when focusing its center of interest. Placing the cursor over a model and pressing the F hotkey focuses the camera on the spot under the cursor.

Import Autofocus

Determines if and when the camera automatically focuses on objects when they are imported. The options are: Empty Scene Only, Always, and Never.

Local Focus

Sets the aim point for the camera to the location that the sculpting brush touched last. This option prevents the model from tumbling very far from the current view whenever you are sculpting close up.

Dolly Amount

Determines how much the camera dollies while focusing. The value indicates how much screen space the brush ring display covers after the camera focuses on the center of interest. For example, a value of 100 means the camera will dolly in until the brush ring fills 100 percent of the screen.

Status Line

Selected Face Count

Displays the number of selected faces in the scene, on the status bar.

Visible Face Count

Displays the number of visible faces in the scene, on the status bar.

FPS

Indicates the rate at which the 3D View is refreshed as a value in frames -per-second.

Save Reminder

Displays a timer on the status bar that counts the time from the last save. When the timer reaches the limit set in the Minutes option, the Save reminder box on the status bar flashes red with the word Save. Clicking the red Save reminder box cancels the current reminder and resets the timer.

Minutes

Specifies the time before the Save reminder box flashes indicating it’s time to save the file.
