Unigine::Object Class

Header: #include <UnigineObjects.h>
Inherits from: Node

An object with a set of surfaces to represent geometry. Rendering materials are assigned per object surface. An object can be assigned a physical body.

Object Class

Enums

SURFACE_SHADOW_MODE#

NameDescription
SURFACE_SHADOW_MODE_MIXED = 0Mode to cast shadows from both static and dynamic light sources.
SURFACE_SHADOW_MODE_DYNAMIC = 1Mode to cast shadows only if the surface is lit by a dynamic light source.

SURFACE_LIGHTING_MODE#

NameDescription
SURFACE_LIGHTING_MODE_STATIC = 0Optimized for use in static GI, static reflections and cached shadows.
SURFACE_LIGHTING_MODE_DYNAMIC = 1Excludes the surface from use in static GI and static reflections and is suitable for dynamic shadows.
SURFACE_LIGHTING_MODE_ADVANCED = 2Enables manual adjustment of all lighting-related settings.

STREAMING_OBJECT_MESH#

NameDescription
STREAMING_OBJECT_MESH_ON_DEMAND = 0Mesh streaming mode to load mesh to RAM/VRAM on demand.
STREAMING_OBJECT_MESH_BY_PRESENCE = 1Mesh streaming mode to load mesh to and hold in RAM/VRAM by its presence. The mesh remains loaded while it exists. This mode can be set for a single mesh participating in collisions and intersections to avoid incorrect physical behavior of objects in the scene.
