To add one or more source compositions to Reaction in a single step:
1 Select the Reaction tool in the Schematic view or select the desired
Reaction in the Layer Editor.
2 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.
3 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.
NOTE You can immediately change the surface geometry of the layer using
options in the Type column of the Layer Editor.
NOTE You 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.
Working with Maya Pre-Comps
Once created, you can automatically generate and update compositions based
on Maya render layer and pass setups. This accelerates and streamlines the 3D
to 2D workflow by allowing the 3D artist to pre-visualize a scene in the form
of the final composite while continuing to iterate on and refine only required
elements. The format supports different passes per layer and per camera; passes
from pairs or sets of cameras can be imported side-by-side within a
composition, allowing their dependency graphs to be manipulated in tandem,
and making it easy to select pairs of nodes for viewing as stereoscopic output.
