The Particle Adapter component adapts the output of size-independent components (such as Image, Selection, Color Control, Grayscale Control and Frame) for use by Particle inputs of the Bomber component. Essentially, Particle Adapter strips them of their size-independence, making them react to changes of the global Size slider, just as most components do.
Particle Adapter is a map component, it can be located in the Patterns category on the Components Bar. This component can output HDR colors.
If you plug a size-independent component, for example Image, directly into a Particle input of the Bomber component and change the Size slider to any value lower than the maximum, the particle image will get clipped. Routing the connection through Particle Adapter eliminates the clipping problem:
There’s only one situation where you need Particle Adapter: when a size-independent component is used in the subtree for Particle 1 – Particle 5 inputs of the Bomber component, you need to route this connection through Particle Adapter to achieve optimal results. If you plug Particle Adapter in any other input, it will show a connection warning.
Source: Map Input (HDR), Required
Provides the source image. All pixels of the Source image are marked for anti-aliasing: this is done to eliminate aliasing artifacts that occur when a particle is downscaled by a Bomber component. This is a required input – in order to make Particle Adapter work, this input must be connected. This input can accept HDR colors.
