Hide and show UV tiles on a model

The remaining texture tiles are not displayed until you manually load them. Any unloaded texture tiles are automatically assigned a random color to indicate their unloaded state in the 3D View. Mudbox displays a message in the 3D View if you attempt to paint on an area of the model where the UV tile is unloaded.

Working with very high resolution textures on models with multiple UV tiles can quickly use up limited graphics memory when all textures are set to display simultaneously, depending on the number and resolution of the paint layers.

To let you work effectively on models with multiple UV tiles, Mudbox automatically optimizes the display of textures. When a model containing multiple UV tiles (with at least one paint layer) is open in Mudbox, only one texture tile on the model is set to display in the 3D View. The texture tile displayed by default is determined by its proximity to the UV origin in UV texture space. That is, the closest tile to the 0, 0 origin is the first tile displayed by default.

To...	Do this
Toggle the display of a texture tile on a model	Position the cursor over the texture tile region and press the Up arrow key . This toggles the display of the textures for that one tile region for all paint channels on or off. When a texture tile is turned off, a random color appears in place of the texture to indicate that the UV tile for that region is currently unloaded.

NoteYou can change the default hotkey for toggling the display of texture tiles by selecting Windows > Hotkeys.

Randomly coloring the unloaded UV tiles lets you determine:

Mudbox is currently optimizing the display of the UV tiles to save video memory. It also indicates that multiple UV tiles exist on the model.
The location of each texture tile on the model in relation to one another and which parts of a model are assigned to particular tiles.
Which texture tiles are currently loaded or unloaded on the model so you can selectively load or unload any texture tile(s) when painting as required.

WarningDepending on the number and resolution of texture tiles on your model, showing all of the texture tiles may rapidly use all of the graphics memory on your computer resulting in diminished interactive performance. To learn more about optimizing texture memory, see Graphics memory optimization.
