With the RIB (RenderMan Interface Bytestream) parameters, you can choose to filter the information Nuke generates for RenderMan, set your arguments to it, and output your own RIB file. On the RIB tab:
• filter - check this to filter the information on your scene, generated by Nuke for RenderMan. In order to do this, Nuke calls a Python function called nukescripts.renderman.filterRIB. Filtering can make the render startup slightly slower as a temporary RIB file is created for each render.
• arguments - specify your arguments for filtering. This string is passed by Nuke’s Python filter function as extra arguments to RenderMan. If you want to use your own filter, you can also replace Nuke’s Python function, and have your arguments passed directly to your own Python function. For example, you could set the filter arguments to "-rif myfilter.so" to load your own RenderMan Interface filter.
TIP: For further details on filtering, have a look at your RenderMan documentation.
A RIB file is a RenderMan-compatible ASCII file with information that Nuke generates when rendering your footage. To output a RIB file:
| 1. | In the file field under output, specify the file name and location for your RIB file. |
| 2. | Click Execute. |
