- `Render Output Path` _non-editable_: Final file path where render output will be saved. This is a computed value based on the `Render Output Root` and `Add Path Components` settings.
By using this job type, you can easily distribute Blender rendering tasks across multiple workers in your Flamenco setup, potentially saving significant time on large rendering projects.
## Single Image Render
This built-in job type is designed for distributed rendering of a single image from a Blender file. It splits the image into tiles, renders each tile separately, and then merges the tiles back into a single image. This approach allows for parallel processing of different parts of the image, potentially speeding up the rendering process.
Currently, the job type supports composition, as long as there is one single `Render Layers` node. The job type does not support `Denoising` node.
The job type defines several settings that can be configured when submitting a job:
- `Tile Size X` _integer, default: 64: Tile size in pixels for the X axis, does not need to be divisible by the image width.
- `Tile Size Y` _integer, default: 64: Tile size in pixels for the Y axis, does not need to be divisible by the image height.
- `Frame` _integer, required_: The frame to render. By default, it uses the current frame in the Blender scene.
- `Render Output Root` _string, required_: Base directory where render output is stored. Job-specific parts will be appended to this path.
- `Add Path Components` _integer, required, default: 0_: Number of path components from the current blend file to use in the render output path.
- `Render Output Path` _non-editable_: Final file path where render output will be saved. This is a computed value based on the `Render Output Root` and `Add Path Components` settings.
Choosing the right tile size is crucial for performance. Too small tiles might increase overhead, while too large tiles might not distribute the workload effectively.
