Detailed Description

Get the maximum number of render passes that will be used to render the scene graph. multipassStatus() and multipassNode return a bit mask of length 32 that holds 1 at position i if the node will be i-th drawn in the i-th render pass.

So if renderPass() == 0x00...001011, the node will be drawn during render pass 1, 2 and 4.

Note:

This class implements an action that should be used as a parameter for the traverse() functions.
