Renderman procedural parameters

name	type	description
cachePath	RtToken	Atoms cache path, the folder where the atoms cache is located or the full path to the cache .atoms file header (i.e. /../../foo_path/mycache.atoms)
cacheName	RtToken	Atoms cache name, this can be an empty value if the full cache path is provided in the cachePath attribute
variationsPath	RtToken	This is the full path to the json variation table. This can also be the serialized variation table which can be retrieved by the following code. json_table_str = "...……….." json_data = Atoms.loadVariationFromRtToken(json_table_str) variationsStr = json_data.toRtToken(False) vm = AtomsCore.RtTokenMetadata(variationsStr) ark = AtomsCore.Archive(vm.memSize()) vm.serialise(ark) variations_serialized = ark.encodeBase64(True)
time	RtFloat	Cache time. You can use this or frame, depending on the DCC you are in. Internally the procedural use time+frame+timeOffset as cache time
frame	RtFloat	Cache frame. You can use this or time, depending on the dcc your are in. Internally the procedural use time+frame+timeOffset as cache time
timeOffset	RtFloat	Cache time offset
shutter	RtFloat2	Float array of length 2 containing the shutterOpen and ShutterClose. Depending on your DCC you should this or the two shutterOpen/Close attributes. Internally the procedural compute shutterOpen+shutter[0] and shutterClose+shutter[1]
shutterOpen	RtFloat	Depending on the DCC you are in use this or the shutter[0] attributes. Internally the procedural compute shutterOpen+shutter[0] and shutterClose+shutter[1]
shutterClose	RtFloat	Depending on the DCC you are in use this or the shutter[1] attribute. Internally the procedural compute shutterOpen+shutter[0] and shutterClose+shutter[1]
numMotionBlurKeys	RtInt	Number of motion blur samples
agentIds	RtToken	Agent ids to load. You can provide multiple ids using the comma to separate them, you can also use - to specify a range or ! to remove agents. Like 2-8,13,15-18 or !8,!10 or !(2-10)…
meshFilter	RtToken	List of mesh to filter. You can provide multiple comma separated mesh names (without whitespaces). You can use * as wildcard and ! to negate. For instance body,head or !*body...
offset	RtFloat3	Cache translation offset.
disableVariationMaterials	RtToken	This disable materials from the variation table. You can provide multiple comma separated values (without whitespaces). You can use * as wildcard.
sceneMaterials	RtToken	List of the materials the procedural should load from the current scene and not from the variation table. You can provide multiple comma separated values (without whitespaces). You can use * as wildcard and ! to negate
materialOverrides	RtToken	Connect a material to a specific mesh. You can provide multiple comma separated values. The syntax is meshName:materialName. You can use the * as wildcard. I.e. *_head:yourNewMaterial
disableDefaultMaterial	RtInt	Disable the green shader if there is no valid shader inside the variation table or there is no variation metadata on the agents.
atomsShaderAttributePrefix	RtToken	The procedural transfers every agent metadata to the skinned mesh using "atomsShaderAttributePrefix+metadataName" as name. You can use this data to drive shader parameters. Default value "atoms_"
agentType	RtToken	Override agent type. You can provide multiple comma separated values. To override the variation of every agent provide an agent type name. If you want override specific agents use the following syntax: agentId@agentType. I.e. 1@robot,4@soldier,6-15@robot
agentVariation	RtToken	Override agent variation. You can provide multiple comma separated values. To override the variation of every agent provide a variation name. If you want override specific agent use the following syntax: agentd@variaitonName. I.e. 1@robot1,4@robot2,6-15@robot4
agentLod	RtToken	Override agent lod. You can provide multiple comma separated values. To override the lod of every agent provide just the lod value. If you want override specific agent use the following syntax: agentd@lodValue. I.e. 1@lodA,4@lodC,6-15@lodB
agentMetadata	RtToken	Override or create agent metadata (only bool, int, double, vec3 and RtToken). You can provide multiple comma separated values. Use the following syntax, agentId@metadataname#value. I.e. 10@myIntMetada#10 20@myBoolMetada#true 10-25@myDoubleMetada#12.5 10-25@myVector3Metada#1.0;2.0;3.0 10-25@myRtTokenMetada#test
clothCachePath	RtToken	Atoms cloth cache path, the folder where the atoms cache is located or the full path to the .clothcachefile header. i.e. /../../foo_path/mycache.clothcache
clothCacheName	RtToken	Cloth cache name, this can be an empty value if the full cache path is provided in the clothCachePath attribute.
groomCachePath	RtToken	Path to one of the alembic file generated by the alembic cache exporter (with groom option activated).
groomCurvesCachePath	RtToken	Path to one of the alembic file generated by the cfx cache exporter.
useInstances	RtInt	Activates the agent instancing
useFrustumCulling	RtInt	Activates frustum culling
frustumCullingOverscan	RtFloat3	Overscan similar to the maya camera overscan used by the frustum culling
frustumCullingProjectionMatrices	RtMatrix	Array of camera model view projection matrices. If you use this attribute, It must have the same length of the motion blur samples.
frustumCullingProjectionMatrix	RtMatrix	If there is no frustumCullingProjectionMatrices, the procedural uses this camera model view projection matrix for all the motion blur samples.
agentVariationOverride	RtToken	Specify an override for the variation overrides of this atoms proxy agents. You can override one character using a string in the following format: agentId@VariationOverride (i.e. 1@with_glasses)
agentGeometryFilterOverride	RtToken	Specify a geometry filter override for this atoms proxy agents. You can override one character using a string in the following format: agentId@GeometryName (i.e. 1@glasses_GEO)
agentGeoMatOverride	RtToken	Specify a geo-mat combination override for this atoms proxy agents. You can override one character using a string in the following format: agentId@GeometryName-MaterialName(i.e. 1@glasses_GEO-boy_glasses_black_MAT)
matteOverride	RtInt	Matte override. Default value: -1
objectIdOverride	RtInt	Object ID override: Default value: -1
