Members

Inherited from class RenderGraphNode

Plugs:

RW ActiveContexts nil The contexts in which this node is active, or an empty string to be always active
RW Invalid nil The invalidation plug. Invalidating this plug causes all RenderGraphOutputs of this node to be invalidated. This plug is dependent on all RenderGraphInputs
RW NodePos types.table The node position in the graph, as {x,y} components
RW State nil The node state, either "active", "bypass" or "disabled". When "disabled", all outputs values are nil. When "bypass", all outputs values are the node's first node input's value.

Inherited from class Procedural

Plugs:

string Script RW The LUA script describing the primitive. This script must be written in the LUA syntax. LUA{ local plugin = {} function plugin:getlaabb () return aabb.create (0, 1, 0, 1, 0, 1) end function plugin:subdivide (parameters) RiPolygon ("P", {0,0,0,0,0,1,1,0,1,1,0,0}, "st", {0,0,0,1,1,1,1,0}, "N", {0,1,0,0,1,0,0,1,0,0,1,0}) end return plugin }

Methods:

nil bake ( ) Bake the procedural and pass it in "Read" mode. This methods is only for the HairAndFur procedural.
nil baketoarchive ( string file ) Write the procedural geometry to the given file (only ghostdata and obj files are supported at the moment)
ref ProceduralRef createref ( Node parent , string name , string filename ) Create a ProceduralRef to a gprocedural file

Functions:

nil bakeall ( ) Bake the procedurals which are marked as Bake
nil forceallbaked ( ) Force all the procedurals as Bake, then bake tham all, and force them all as Read back.
