(Edit Current Event)

The Image Alpha filter replaces the image's alpha channel with the channel specified by the filter mask.

The filter takes whatever channel is selected in the channel options under Mask (including g-buffer channel data) and applies it to the queue's alpha channel, thereby replacing what's there.

If you don't choose a mask, this filter has no effect.

There are no setup options for this filter.

Procedures

To set an object's G-Buffer ID:

Select the object.
Right-click the object and then choose Properties from the popup menu.
In the Object Properties dialog, set G-Buffer Object Channel to a nonzero value, and then click OK.
The G-Buffer ID can be any positive integer.

If you give the same G-Buffer ID value to more than one object, all these objects will be post-processed.
