Composite nodes have several modes, each of which can have a specific purpose in a complex node system:
As Bitmap: This is the default mode for composites. A bitmap composite outputs a single composited image.
As Seamless Bitmap: mode works very similarly to bitmap mode, except it prevents seams from appearing between vector shapes that have matching outlines or when vector drawings are 3D-rotated and made to mesh together.NOTE Shadow, Glow, Blending and Focus effects do not work when connected to a Seamless Bitmap composite.
As Vector: This mode outputs a flat vector drawing made of all the connected drawings. Vector composites should be used only when necessary, as they ignore any effect and bitmap information that is sent to them.
Pass Through: This mode simply passes all the information sent to the Composite, including artwork, effects and transformations, onto the next composite as is, as a multi-layered image. This means that if an effect is applied to the output of that composite, the effect will be applied individually to each layer connected to that composite. Hence, a pass through composite does not really perform any composition. It is essentially an organization tool.NOTES
- The cable coming from a Pass Through composite will be thicker and have a darker centreline. This can be useful to identify areas of your node system that carry a lot of information.
- If a Composite set to Pass Through is at the bottom of the composite chain, it will act the same as a Bitmap composite.
