Detailed Description

Procedural to render a single GT primitive.

When rendering GT primitives, they will be refined until they hit geometry that Mantra can handle.

When GT_PRIM_INSTANCE primitives are encountered, the procedural will create multiple instance objects in mantra, allowing the geometry to be shared between instances automatically. In addition, the following uniform/detail attributes are handled on the instance primitives:

shop_materialpath
Assign a material for the instance. This calls RAY_Procedural::setShopMaterialPath(). If the shop_materialpath is found, then additional attributes (material_override and property_override) are evaluated to handle shader argument and property overrides.

lightcategories
Set the lightcategories property on the instance

lightmask
Set the lightmask property on the instance. Note that this may not handle light instancing properly.
categories
Set the categories for instance.

RAY_ProcGT::RAY_ProcGT	(	const GT_PrimitiveHandle &	prim,
		bool	use_multi_segments = `true`,
		fpreal	shutter_close = `-1`
	)

A mantra procedural to render a GT primitive. If the GT primitive has multiple segments, the primitive will be rendered with deformation motion blur unless use_multi_segments is false.

When multi-segment blur is active, the shutter_close can be specified. If the shutter_close is less than 0, the value will be imported from the camera:shutter setting. If shutter_close is 0, multi-segment blur will be disabled.

If the GT primitive has the proper sub-frame sampling time, then you likely want to set the shutter_close to 1.0.

RAY_ProcGT::RAY_ProcGT	(	const UT_Array< GT_PrimitiveHandle > &	primitives,
		fpreal	shutter_close = `-1`
	)

Alternatively, motion segments can be specified using an array of primitives.
