The ROP Node
The core of the Redshift for Houdini plugin is the Redshift ROP node. This ROP node is similar to the other Houdini render nodes and a lot of options are identical. You can add the Redshift ROP node from the Redshift shelf, from the Render->Create Render Node menu or using the TAB menu in the /out context.
In the Redshift ROP node you have all the options to configure the render:
- Common options, like the frame range and the takes configuration.
- Render camera, camera resolution override and global environment.
- Global scene materials overrides.
- Render options related to the simulations, multithreaded scene loading or scene update modes.
- The render output options: Render to MPlay and/or to file, all the AOVs options and the gamma settings.
- All the Redshift renderer options: Sampling, Motion Blur, Render settings, Global Illumination parameters, SSS and Volumetric options and the System and Memory settings.
- The tools to export objects or scenes as Redshift Proxy files.
- The render maps options to configure the texture baking feature.
- Set the objects candidates, force or exclude lists.
- Configure pre and post render scripts.
- Configure the IPR settings: IPR camera, resolution, etc.
Non-Blocking Current Frame Rendering
To render multiple ROP nodes in a chain you must disable the “ Non-blocking current frame rendering ” option in every ROP node.
Global material override
The ROP node has an option to full override all the scene materials. Any material available in the scene can be used as override, and there is an additional parameter to exclude one or more objects from the override.
AOV custom prefix name
Each AOV has a parameter to set a custom prefix path name for it. If left blank, the common prefix path is used. While working with multi-layered EXR files, all the AOVs with the same custom prefix will be stored in the same EXR file
AOV suffix name
The Redshift ROP has an additional variable “ $AOV ” that can be used to set the AOV suffix name in the output image file name. If this variable is not found, the plugin append the AOV suffix to the end of the file name, just before the file type extension.
Sequence rendering update mode
By default, the Redshift plugin will extract and process all the mesh objects geometry and materials for each frame while rendering a sequence.
If you are rendering an animation without mesh changes (for example an animation with only camera, lights or objects transformations), you can disable the“ Sequence Rendering Full Scene Reload” option in the RS ROP node to eliminate near all the extraction time among the frames.
With this option disabled, you can enable an additional option “ Sequence Rendering Update Mesh Geometry” to only update the mesh geometry data of the scene objects (without full reload all the scene). The strength of this feature is that you can use a bunde list to select what object(s) must be updated by the plugin among the frames.
