MaterialInstance Class

Definition

Namespace:

Microsoft.MixedReality.Toolkit.Rendering

Assembly:

Microsoft.MixedReality.Toolkit.dll

The MaterialInstance behavior aides in tracking instance material lifetime and automatically destroys instanced materials for the user. This utility component can be used as a replacement to Renderer.material or Renderer.materials. When invoking Unity's Renderer.material(s), Unity automatically instantiates new materials. It is the caller's responsibility to destroy the materials when a material is no longer needed or the game object is destroyed. The MaterialInstance behavior helps avoid material leaks and keeps material allocation paths consistent during edit and run time.

Properties

CacheSharedMaterialsFromRenderer	Whether to use a cached copy of cachedRenderer.sharedMaterials or call sharedMaterials on the Renderer directly. Enabling the option will lead to better performance but you must turn it off before modifying sharedMaterials of the Renderer.
Material	Returns the first instantiated Material assigned to the renderer, similar to Renderer.material.
Materials	Returns all the instantiated materials of this object, similar to Renderer.materials.

Methods

AcquireMaterial(Object, Boolean)	Returns the first instantiated Material assigned to the renderer, similar to Renderer.material. If any owner is specified the instanced material(s) will not be released until all owners are released. When a material is no longer needed ReleaseMaterial should be called with the matching owner.
AcquireMaterials(Object, Boolean)	Returns all the instantiated materials of this object, similar to Renderer.materials. If any owner is specified the instanced material(s) will not be released until all owners are released. When a material is no longer needed ReleaseMaterial should be called with the matching owner.
ReleaseMaterial(Object, Boolean)	Relinquishes ownership of a material instance. This should be called when a material is no longer needed after acquire ownership with AcquireMaterial(s).
