Properties

Property group 'Material'

bDisableDepthTest

Type: bool

Allows the material to disable depth tests, which is only meaningful with translucent blend modes. Disabling depth tests will make rendering significantly slower since no occluded pixels can get zculled.

BlendMode

Type: EBlendMode

Determines how the material's color is blended with background colors.

FallbackMaterial

Type: Material

The fallback material, which will be used on sm2 platforms

LightingModel

Type: EMaterialLightingModel

Determines how inputs are combined to create the material's final color.

OpacityMaskClipValue

Type: float

If BlendMode is BLEND_Masked, the surface is not rendered where OpacityMask < OpacityMaskClipValue.

Default value: 0.3333

PhysMaterial

Type: PhysicalMaterial

Physical material to use for this graphics material. Used for sounds, effects etc.

TwoSided

Type: bool

Indicates that the material should be rendered without backface culling and the normal should be flipped for backfaces.
