Properties

Property group 'MaterialExpression'

Desc

Type: string

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

Internal variables

bHidePreviewWindow

Type: bool

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

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.

bNeedToUpdatePreview

Type: bool

Modifiers: transient

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

bRealtimePreview

Type: bool

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

bShowOutputNameOnPin

Type: bool

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

Compound

Type: MaterialExpressionCompound

Modifiers: const

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

EditorX

Type: int

Modifiers: deprecated

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

EditorY

Type: int

Modifiers: deprecated

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

MaterialExpressionEditorX

Type: int

Modifiers: editoronly


MaterialExpressionEditorY

Type: int

Modifiers: editoronly
