(Edit Current Event)
The Simple Additive compositor composites the two images using the second image's intensity (HSV value) to determine transparency.
Areas of full intensity (255) are opaque; areas of zero intensity are transparent; and areas with intermediate transparency
are translucent.
This layer event can be useful when the second image is a bitmap whose format does not have an alpha channel.
There are no setup options for this compositor.
Procedures
To use the Simple Additive Compositor:
- Add two Scene or Image Input events to the queue.
- Select both events and assign an Image Layer event consisting of the Simple Additive Compositor.
