[edit] Properties

[edit] Property group 'MaterialExpression'

[edit] Desc

Type: string

A description that level designers can add (shows in the material editor UI).

[edit] Internal variables

[edit] bHidePreviewWindow

Type: bool

If TRUE, do not render the preview window for the expression

[edit] bIsParameterExpression

Type: bool

Indicates that this is a 'parameter' type of expression and should always be loaded (ie not cooked away) because we might want the default parameter.

[edit] bNeedToUpdatePreview

Type: bool

Modifiers: transient

If TRUE, we should update the preview next render. This is set when changing bRealtimePreview.

[edit] bRealtimePreview

Type: bool

Set to TRUE by RecursiveUpdateRealtimePreview() if the expression's preview needs to be updated in realtime in the material editor.

[edit] bShowOutputNameOnPin

Type: bool

If TRUE, use the output name as the label for the pin

[edit] Compound

Type: MaterialExpressionCompound

Modifiers: const

A reference to the compound expression this material expression belongs to.

[edit] EditorX

Type: int

Modifiers: deprecated

This variable is conlficting with Materia var, making new ones (MaterialExpressionEditor), and then deprecating this *

[edit] EditorY

Type: int

Modifiers: deprecated

This variable is conlficting with Materia var, making new ones (MaterialExpressionEditor), and then deprecating this *

[edit] MaterialExpressionEditorX

Type: int

Modifiers: editoronly

[edit] MaterialExpressionEditorY

Type: int

Modifiers: editoronly

[edit] MenuCategories

Type: array<name>

Categories to sort this expression into...

[edit] Structs

int Mask 

int MaskR 

int MaskG 

int MaskB 

int MaskA 

int GCC64_Padding 

Todo: 64: if the C++ didn't mismirror this structure (with MaterialInput), we might not need this
