Render Output Location¶

RenderingAPI.RenderOutputLocation.GetPlugin()¶

RenderingAPI.RenderOutputLocation.GetPluginNames()¶

class RenderingAPI.RenderOutputLocation.RenderOutputLocationPlugin¶

Bases: object

render output location plugin

__hash__¶

__init__¶

x.__init__(...) initializes x; see help(type(x)) for signature

__new__(S, ...) → a new object with type S, a subtype of T¶

computeFilePath(outputAttrs, locationAttrs, renderSettingsAttrs, imageInfo, makeVersionTemplate) → string¶

Uses the RenderOutputLocation plugin to resolve a file path for the render. The first three arguments should be dictionaries of string -> string or dictionaries of string -> FnAttribute.Attribute. makeVersionTemplate should be an boolean value.

computeLocation(outputAttrs, locationAttrs, renderSettingsAttrs, imageInfo) → string¶

Uses the RenderOutputLocation plug-in to compute a location for the render. Arguments should be dictionaries of string -> string or dictionaries of string -> FnAttribute.Attribute.

RenderingAPI.RenderOutputs.GetRenderOutputs(client, includeMerge=False)¶

Render Plugins¶

RenderingAPI.RenderPlugins.GetAllRenderMethods()¶

RenderingAPI.RenderPlugins.GetBatchRenderMethodForRenderer(rendererName)¶

RenderingAPI.RenderPlugins.GetDefaultRendererPluginName()¶

Use the Configuration Singleton to get the default renderer. If there is no entry in the Singleton then returns the first available renderer.

RenderingAPI.RenderPlugins.GetInfoPlugin(rendererName)¶

RenderingAPI.RenderPlugins.GetInfoPluginName(rendererName)¶

RenderingAPI.RenderPlugins.GetInfoPluginNameForShaderType(shaderType)¶

RenderingAPI.RenderPlugins.GetOutputChannelAttr(rendererName, dynamicOnly=False)¶

Retrieves a renderer’s output channel settings from the RendererInfoPlugin and applies some processing before returning the attributes and hints.

This is used both in GetOutputChannelDynamicParameters above as well as the OutputChannelDefineDefaultAttrProducer.

RenderingAPI.RenderPlugins.GetOutputChannelDynamicParameters(rendererName)¶

Attributes defined in xxxRendererInfo.cpp can have dynamic parameter groups. For Arnold for example, this would be filter and driver.

Once the filter value is changed, the ‘filterParameters’ group is automatically reloaded. To specify this relationship, two hints can be set on the attribute (in this case ‘filter’):

• dynamicParameters: filterParameters
• dynamicParametersType: kFnRendererObjectTypeFilter

This function extracts these two flags from a renderer’s output channel settings.

RenderingAPI.RenderPlugins.GetOutputChannelGlobalStatementsAttr(rendererName)¶

Builds the hints on the xxxGlobalStatements level.

For example the page hint for Arnold.

RenderingAPI.RenderPlugins.GetOutputChannelParameters(rendererName)¶

Returns a list of output channel parameters.

Used by GetOutputChannelAttr and the generic OutputChannelDefine node.

RenderingAPI.RenderPlugins.GetProcessedParams(paramList, hintDict={})¶

Iterates over a list of parameters from a RendererInfoPlugin and adds additional hints for better formatting.

This is used in GetOutputChannelAttr above as well as from within the OutputChannelDefineDefaultAttrProducer.

RenderingAPI.RenderPlugins.GetRenderMethodByName(methodName, rendererName=None)¶

RenderingAPI.RenderPlugins.GetRenderMethodForRendererAndMethodName(rendererName, methodName, includeBatch=True)¶
