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.
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.
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.
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.
By default, the selected object is exported based on its current subdivision level and any detail contained on the sculpt layers associated with that subdivision level when exporting using FBX.
Turn this option on if you want to preserve the separate sculpt layers on the current subdivision level as individual blendshapes. This produces separate blend shape targets that can be modified in Maya/Max in a manner similar to the Layer Opacity slider within Mudbox.
By default, when a Mudbox scene is exported using FBX, a subdirectory titled <filename> .fbx-files is created to store any existing paint layers (textures).
If the Mudbox scene has been previously saved and a -files subdirectory already exists, the -files directory can be referenced instead.
Select this preference to export an .fbx file that references the same -files subdirectory as the .mud scene.
By default, any paint layers that exist on a model being exported (including the background color) are saved as discrete textures when exporting from Mudbox using the FBX format. If the 3D application supports it, the textures usually appear as layered textures on the model's shading material.
Some 3D applications do not universally support multiple layered textures within a single texture channel. In these circumstances, turning on the Flatten Paint Layers On Export is recommended. This causes the paint layers to be merged into one texture per channel during export. The flatten operation also includes the background color for the material.
By default, any assigned materials and textures that exist in an FBX file are automatically imported into Mudbox with the mesh. If you do not want materials and textures to be imported with the mesh, turn off the Import Materials and Textures preference. The default Mudbox Material is assigned when this preference is turned off.
The Brush Sample Area controls the sample size for paint brushes directly beneath the brush ring. In most circumstances, the default setting of 0 should be sufficient.
When painting on models that have very narrow/thin faces or larger faces relative to the size of the brush tip, visible artifacts can be produced.
In these situations, increasing the value of the Brush Sample Area increases the sample area to extend outside the brush ring to determine the brush effect. For example, a value of 1 doubles the area that is calculated.
Interactive performance of paint brushes can decrease as the Brush Sample Area value is increased.
Sets the unloaded base tile color that appears on an area of the model when the associated UV texture tile is unloaded on a multi-tiled model to be the same color as the current material color. That is, there is no color differentiation between loaded and unloaded tiles when this preference is turned off. For more information, see Hide and show UV tiles on a model.
Specifies the size of a border that is automatically extended outside the perimeter of a UV shell when painting on a model. Extending paint pixels beyond the perimeter edges is used to reduce the appearance of seams on a painted model where separate UV shells meet.
A value of 0 specifies no edge bleed. A value of 1 specifies a one pixel border width outside the shell, while a value of 2 specifies a 2 pixel border width (based on a 1024 x 1024 resolution texture image). A value of 2 specifies a 4 pixel border when the image texture resolution is 2048 x 2048. Working range is between 0 and 10.
