[edit] bHasStaticPermutationResource

Type: bool

indicates whether the instance has static permutation resources (which are required when static parameters are present)

[edit] bStaticPermutationDirty

Type: bool

Modifiers: native, transient

indicates whether the static permutation resource needs to be updated on PostEditChange()

[edit] ParentLightingGuid

Type: Object.Guid

Modifiers: private, const

Unique ID for this material, used for caching during distributed lighting

[edit] ReentrantFlag

Type: bool

Modifiers: private, const, native

[edit] ReferencedTextureGuids

Type: array<Object.Guid>

Modifiers: private, const, editoronly

[edit] ReferencedTextures

Type: array<Texture>

Modifiers: private, const

Array of textures referenced, updated in PostLoad. These are needed to keep the textures used by material resources from getting destroyed by realtime GC.

[edit] Resources

Type: pointer{class FMaterialInstanceResource}

Array size: 2

Modifiers: const, native, duplicatetransient

[edit] StaticParameters

Type: pointer{FStaticParameterSet}

Array size: 2

Modifiers: const, native, duplicatetransient

The set of static parameters that this instance will be compiled with, one for sm3 and one for sm2. This is indexed by EMaterialShaderPlatform.

[edit] StaticPermutationResources

Type: pointer{FMaterialResource}

Array size: 2

Modifiers: const, native, duplicatetransient

The material resources for this instance, one for sm3 and one for sm2. This is indexed by EMaterialShaderPlatform.

[edit] Native functions

[edit] ClearParameterValues

Removes all parameter values

[edit] IsInMapOrTransientPackage

Returns if this MI is either in a map package or the transient package During gameplay, Set..Parameter should only be called on MIs where this is TRUE - otherwise you are modifying an MI within a content package, that will persist across level reload etc.
