Global Settings and Defaults for Bitmap Proxies Dialog

This dialog lets you determine how 3ds Max should create and use proxy versions of bitmaps incorporated in materials. It also lets you disable or enable bitmap paging.

• Asset Tracking dialog > Bitmap Performance And Memory menu > Global Settings
• Asset Tracking dialog > Highlight bitmap asset(s). > Bitmap Performance And Memory menu > Set Proxy Resolution
• Asset Tracking dialog > Right-click a bitmap asset. > Set Proxy Resolution
• Render Setup dialog > Common panel > Common Parameters rollout > Bitmap Performance And Memory Options group > Setup

Proxies are intended for use primarily in the viewports when building and editing scenes to reduce the amount of memory required by the bitmapped textures, but you can also use them at render time.

Note: When you open this dialog using either of the Set Proxy Resolution commands cited at the top of this topic, the title changes to Per-Bitmap Resolution for Bitmap Proxies, the Enable Proxy System checkbox changes to Use Global Settings, and you can set only the proxy resolution.

Proxy Resolution group

The label and function of the first checkbox on the dialog depends on whether you invoked it with Setup/Global Settings command or Set Proxy Resolution:

• Enable Proxy System Toggles usage of the proxy system. When off, 3ds Max uses only the original, full-resolution maps. Available only on the Global version of the dialog.
• Use Global Settings When on, the proxy system applies the same settings to all bitmaps subject to proxy substitution, as set via the Global version of the dialog. When off, use the Downscale Map ... setting (see following) to specify resolution only for bitmaps highlighted before invoking Set Proxy Resolution. Available only on the Per-Bitmap version of the dialog.

Downscale map to [...] original size.

Use the drop-down list to choose the fraction to which the proxy system reduces the bitmap(s): Full (no reduction), Half, Third, Quarter, or Eighth. The greater the reduction, the greater the memory savings and speed improvement, especially in a scene with many maps, but the less recognizable the map.

Proxy System group

These settings are available only when you open the dialog using the Setup or Global Settings commands cited at the top of this topic.

Use proxy only if the original map's largest dimension is greater than [...] pixels.

Lets you indicate that bitmaps smaller than the size you specify are not to be reduced. Downscaling smaller maps isn't particularly efficient or useful.

To ensure that the system creates proxies for all bitmaps, set this to 0.

Render Mode

Lets you determine whether to use the proxies at render time. The options, available from the drop-down list, are self-descriptive:

• Render with Proxies (High Performance, Low Memory)
• Render with Full Resolution Images and Keep them In Memory (High Performance, High Memory)
• Render with Full Resolution Images and Free them from Memory (Low Performance, Low Memory)

Proxy Cache Folder

This read-only field displays the path in which 3ds Max stores proxy bitmap files. To change the path, go to Configure User Paths File I/O and edit the BitmapProxies entry.

Textures and Rendered Images Memory Options group

Page Large Images to Disk (Saves Memory)

When on, 3ds Max uses a page file on disk when it handles large bitmap textures or large renderings. This can save memory, at a cost of some performance time. Default=on.

Page File Location

This field shows the path name of the folder where the page file is saved.

To change the location of the page file, use the Configure System Paths command.

OK, Generate Proxies Now

Generates proxy bitmaps as specified by the dialog settings and closes the dialog.

OK, Generate Proxies Later

Saves the dialog settings and closes the dialog but does not generate proxy bitmaps. You must generate the proxies manually using the Generate Selected/Stale Proxies command from the Asset Tracking dialog.

Cancel

Closes the dialog without saving any changed settings.
