VRay procedural parameters

name	type	description
cachePath	string	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	string	Atoms cache name, this can be an empty value if the full cache path is provided in the cachePath attribute
applyVariations	bool	Apply the variations
variationsPath	string	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.loadVariationFromString(json_table_str) variationsStr = json_data.toString(False) vm = AtomsCore.StringMetadata(variationsStr) ark = AtomsCore.Archive(vm.memSize()) vm.serialise(ark) variations_serialized = ark.encodeBase64(True)
time	float	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
globalTransform	paramtype_transform	Global transform
motionBlur	bool	Activate motion blur
motionBlurDuration	double	Motion blur duration
motionBlurIntervalCenter	double	Motion blur interval center
motionBlurSamples	int	Number of motion blur samples
agentIds	string	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	string	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	vector	Cache translation offset.
disableVariationMaterials	string	This disable materials from the variation table. You can provide multiple comma separated values (without whitespaces). You can use * as wildcard.
sceneMaterials	string	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	string	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	int	Disable the green shader if there is no valid shader inside the variation table or there is no variation metadata on the agents.
atomsShaderAttributePrefix	string	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	string	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	string	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	string	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	string	Override or create agent metadata (only bool, int, double, vec3 and string). 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@myStringMetada#test
clothCachePath	string	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	string	Cloth cache name, this can be an empty value if the full cache path is provided in the clothCachePath attribute.
useInstances	bool	Activates the agent instancing
useFrustumCulling	bool	Activates frustum culling
frustumCullingOverscan	array3	Overscan similar to the maya camera overscan used by the frustum culling
frustumCullingProjectionMatrices	array	Array of camera model view projection matrices. If you use this attribute, It must have the same length of the motion blur samples.
agentVariationOverride	string	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	string	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	string	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	int	Matte override. Default value: -1
objectIdOverride	int	Object ID override: Default value: -1
