RenderMan's power and flexibility means that a large amount of control is given to the user through its wide variety of settings. All of these settings are exposed in RfK through the PrmanIntegratorSettings, PrmanGlobalStatements and PrmanObjectStatements. The attributes in PrmanGlobalStatements are used to control RenderMan's global Options [DRAFT].
PrmanIntegratorSettings sets the integrator to be used in rendering with RenderMan. Typically for production the PxrPathTracer integrator is chosen.
PrmanGlobalStatements . PrmanObjectSettings is used for per-location Attributes [DRAFT]location Attributes. Since there are only a small number of settings used regularly in both of these nodes, they are each set up to hide the less common attributes by default. The Parameter Layout setting is used to expand or collapse collections of attributes based on common usage: Simple, Advanced, or all. That said, even the Simple layout exposes numerous settings. Below are most useful settings in PrmanGlobalStatements:
| Attribute | Default | Description |
|---|---|---|
pixelVariance | 0.005 | Upper bound on the acceptable estimated variance of the pixel values from the true pixel values. |
maxSamples | 0 (64) | Explicit limit for the number of samples. Increase for higher quality, slower render. |
renderDisplay | Monitor | The destination framebuffer for Preview and Live Rendering. Set to 'it' to use RenderMan Image Tool. |
