Setting Paint Preferences

Use the Paint preferences to control various aspects when working with a Paint project, including modifying the size of the render cache.

In Paint, objects are drawn on top of other objects. When you modify an object created earlier in the pipeline, all objects occurring after must be redrawn to display the correct information. The render cache pre-draws objects in memory to increase the speed of screen updates.

To set the Paint preferences:

In the Paint category, select General.

The Paint preferences appear.

Set the following options as required.

Display Brush Outlines

Changes the pointer to an outline that represents the shape and size of the current brush. This option is available for the unfilled drawing tools.

Display Cross Hairs

Displays crosshairs that span the width of the viewport to indicate cursor position. This option is available for the filled drawing tools.

For more information, see Selecting Drawing Tools.

Render Cache Size

Controls the redraw speed of objects. The size is specified in megabytes, with a default value of 4 MB. As a guideline, set this value to the single frame memory requirements of your project, at minimum. For example, if your project is 640 x 480, set this value to at least 1.2 MB.

Note: Global caching in combustion is separate from the Paint Render Cache, and is not affected by these settings.

You can experiment with different Render Cache Size settings. Increase the value if it takes a long time to redraw objects. However, be careful not to set this value too high, as it may interfere with the memory available for rendering effects and other processor-intensive actions.

Note: On a Macintosh, the Render Cache takes memory from the application's memory partition. Therefore, the value cannot be higher than the size of this partition.
