Silhouette-2022 : Nodes : Output / Output Multi-Part
Output / Output Multi-Part
The Output node determines the file format, file name, disk storage location, and channels to be rendered. Every session has at least one Output node.
Output Multi-Part
The Output Multi-Part node is the same as the Output node, but has multiple inputs and renders EXR multi-part files. If there is more than one input, each output part name is appended with the upstream node's name.
The Output Multi-Part node can have multiple additional inputs. Right-click on the Output Multi-Part node and select Add Input. Right-click on an input port to remove it. You can add as many inputs as you want, but the inputs will get smaller.
Node Group
Image, Silhouette.
The format setting allows you to select from various file formats. We currently can save to the following file formats: Cineon, DPX, GStreamer, IFF, JPG, OpenEXR, PNG, SGI/RGB, TIFF and TARGA.
Note: Format is missing from the Output Multi-Part node since it only renders EXR files.
Adjusts options for the selected file format, the majority of which are compression related.
Automatic Data Window
The Automatic Data Window rendering option looks at the alpha channel and determines the data window from that. Then, it writes only the pixels in the data window to an EXR file. For SXR files, it writes the combined data window between the two views. This greatly speeds up loading these files into a compositing system.
Go to the Automatic Data Window tutorial to see how it works.
Determines the directory and filename of the rendered files.
You can either type in the path and name in the File field or click the Browse icon on the right.
As far as filenaming is concerned, you only have to type in a name as periods, hash marks for padding and file extensions are not required unless you want to manually enter them. Silhouette uses the Render Preferences to determine the default suffixes appended to the filename as well as file padding.
If you choose to manually enter the file padding and extension, the filename should have 3 things:
The image name (duh).
# for the frame placeholder.
An extension: .exr = exr files, .cin = Cineon files, .tif = Tiff files, etc.
Therefore, if you enter a name something like test.####.exr,. Silhouette will render out test.0001.exr, test.0002.exr, etc.
Filename Customization
You can add environment variables to the filename using the sfx $(VARNAME) format. Two internal variables are defined for rendering, VIEW and ALPHA. $(ALPHA) expands to _alpha, but only when it is needed for naming external alpha. $(VIEW) expands to L or R, when appropriate.
The default filename expansion, when $(VIEW) and $(ALPHA) are not typed manually (i.e. by default), is this:
If not doing multiple view stereo rendering, it is:
Remember that $(ALPHA) expands to nothing when not needed.
Note: Make sure you type in the full path and base filename into the Output node File field and then Silhouette will do all the substitutions based on the environment variables.
The Metadata field takes whatever you type and adds it to the comments metadata field in EXR files. The format for this field should be a comma-separated list of name=value pairs. For instance, shot=sc125, version=5.
Metadata Notes
Metadata contained in EXR files is passed through to the rendered file.
The metadata for the output node is built from the first input of any upstream nodes.
All EXR string, int, and float attributes are passed through.
The Output > Metadata property now gets broken down into distinct metadata attributes instead of going into the EXR comment field.
Silhouette adds the following attributes for each output part: the output node name, the session name, the project name, the project bundle path and the current user.
Renders the RGB color channels.
Renders the alpha channel.
Renders the depth channel.
The Views pop-up menu allows you to control whether you render the Left, Right or both the Left and Right stereo views simultaneously when working in stereo sessions.
Renders both the Left and Right stereo views with a _L and _R appended to the filenames.
Renders only the Left stereo view with a _L appended to the filename.
Renders only the Right stereo view with a _R appended to the filename.
Go to the Render Preferences to see how to modify the default suffixes appended to the filename.
Premultiplies the RGB channels by the alpha channel. This option is only valid if Channels > RGB and Alpha are selected.
When enabled, the output is cropped/padded to the session size. This becomes relevant when using a ROI (Region of Interest).
Note: Crop/Pad is missing from the Output Multi-Part node since EXR files save the ROI (Region of Interest) as an output EXR data window.
The Sample field displays all of the files that will be produced by the node.
Opens the Render Options window where rendering is initiated.
