You
can composite as many layers as you want using Reaction, but first
you must create the layers. A layer in Reaction is composed of a source
input that you assign to a geometrical support, or 3D geometry,
and a material node that is automatically generated—see
Working with Geometric Surfaces.
NoteTo view the Material
and geometrical support nodes that are generated with a layer, you
must be in the Group Schematic.
If you want to perform
basic multilayer compositing, where you work with bilinear geometric
surfaces only, you can quickly create a layer in a single step in
the Layer Editor or Schematic by using the Reaction drop gate. To
substitute a 3D geometric surface as your layer support, you can
then simply choose a different geometric surface. After creating
the sources and layers, you can publish a 2D composition if you
are satisfied with the results.
To create one or more sources and layers
in a single step:
- In the Schematic view, select the Reaction
node.
- Select images or footage from the File
Browser or desktop, and drop (or stick) them onto the Schematic,
Layer Editor, or Player.
The composition drop
gate appears.
- Swipe through Create Layer.
The sources and layers
are added in the order in which you selected the images/footage
(from first to last) and labeled accordingly in the Layer Editor.
To add a layer:
- Do one of the following:
To add a source:
- In the Schematic view, right-click the
Reaction tool and select Add Source.
- A source input connector
appears in the Schematic view. You can connect media or a tool node
to it.
To add a layer and link to its source:
- In the Layer Editor, right-click a layer
and select Add Linked Layer.
A layer is created and
linked with its source.
To add one or more source compositions
to Reaction in a single step:
- Select the Reaction tool in the Schematic
view or select the desired Reaction in the Layer Editor.
- Select one or more compositions from
the File Browser or Desktop and drop (or stick) them onto the Layer
Editor, Schematic, or Player.
The drop gate appears.
- Swipe through Create Source.
The sources are added
in the order in which you selected the compositions (from first
to last) and are labeled accordingly in the Layer Editor.
To create a layer using a source:
- In the Layer Editor, right-click a source
and select Create Layer Using Source.
A layer is created in
the Layer Editor.
NoteYou can immediately
change the surface geometry of the layer using options in the Type
column of the Layer Editor.
NoteYou can add more
than one layer to a source if you want to create multiple layers
using the same source image. If you have applied effects to the
source image, they will be propagated to the layers to which they
are linked.
