Detailed Description

A Material is an asset which can be applied to a mesh to control the visual look of the scene. When light from the scene hits the surface, the shading model of the material is used to calculate how that light interacts with the surface.

Warning: Creating new materials directly increases shader compile times! Consider creating a Material Instance off of an existing material instead.

BeginDestroy()

void UMaterial::BeginDestroy ( )

overridevirtual

Called before destroying the object. This is called immediately upon deciding to destroy the object, to allow the object to begin an asynchronous cleanup process.

Reimplemented from UMaterialInterface.

CacheShaders()

void UMaterial::CacheShaders ( EMaterialShaderPrecompileMode  CompileMode )

overridevirtual

Submits remaining shaders for recompilation.

This function will submit any remaining shaders to be compiled for the given material. By default these shader compilation jobs will be compiled in the background.

Member Data Documentation

AllowTranslucentCustomDepthWrites

uint8 UMaterial::AllowTranslucentCustomDepthWrites

Allows a translucent material to be used with custom depth writing by compiling additional shaders.

bAllowDevelopmentShaderCompile

uint8 UMaterial::bAllowDevelopmentShaderCompile

If true the compilation environment will be changed to remove the global COMPILE_SHADERS_FOR_DEVELOPMENT flag.

bAllowFrontLayerTranslucency

uint8 UMaterial::bAllowFrontLayerTranslucency

Allows a translucent material to be used with Front Layer Translucency by compiling additional shaders. Useful for controlling what should be included in Front Layer Translucency.

bAllowNegativeEmissiveColor

uint8 UMaterial::bAllowNegativeEmissiveColor

Whether the material should allow outputting negative emissive color values. Only allowed on unlit materials.

bAllowTranslucentLocalLightShadow

uint8 UMaterial::bAllowTranslucentLocalLightShadow

Allows a translucent material to receive local light shadows.

bAllowVariableRateShading

uint8 UMaterial::bAllowVariableRateShading

Allows the use of variable rate shading when evaluating this material. This will only apply to the base/translucency pass.

bAlwaysEvaluateWorldPositionOffset

bool UMaterial::bAlwaysEvaluateWorldPositionOffset

Forces World Position Offset to always be evaluated for this material, even if the primitive it's applied to has disabled it via "Evaluate World Position Offset" or "World Position Offset Disable Distance".

bApplyCloudFogging

uint8 UMaterial::bApplyCloudFogging

When true, translucent materials receive cloud contribution as part of the fog evaluation, per vertex or per pixel according to the other selected options. This is a rough approximation but can help in some cases. Defaults to false. Fog is applied on clouds, so Apply Fogging must be true to use this feature.

bAutomaticallySetUsageInEditor

uint8 UMaterial::bAutomaticallySetUsageInEditor

Whether to automatically set usage flags based on what the material is applied to in the editor. It can be useful to disable this on a base material with many instances, where adding another usage flag accidentally (eg bUsedWithSkeletalMeshes) can add a lot of shader permutations.

bCanMaskedBeAssumedOpaque

uint8 UMaterial::bCanMaskedBeAssumedOpaque

true if this Material can be assumed Opaque when set to masked.

bCastDynamicShadowAsMasked

uint8 UMaterial::bCastDynamicShadowAsMasked

Whether the material should cast shadows as masked even though it has a translucent blend mode.

bCastRayTracedShadows

uint8 UMaterial::bCastRayTracedShadows

when true, the material casts ray tracing shadows.

bCompatibleWithLumenCardSharing

uint8 UMaterial::bCompatibleWithLumenCardSharing

When true, allows to share Lumen Cards between different instances even when material uses world position or per instance data, which may change material look per instance. All materials on a component needs this flag set for sharing to work.

bComputeFogPerPixel

uint8 UMaterial::bComputeFogPerPixel

When true, translucent materials have fog computed for every pixel, which costs more but fixes artifacts due to low tessellation.

bContactShadows

uint8 UMaterial::bContactShadows

Contact shadows on translucency

bDisableDepthTest

uint8 UMaterial::bDisableDepthTest

Whether to draw on top of opaque pixels even if behind them. This only has meaning for translucency.

bDisablePreExposureScale

uint8 UMaterial::bDisablePreExposureScale

Disable pre-exposure scale in post process materials (multiply by View.OneOverPreExposure on inputs, View.PreExposure on output). Useful for materials that don't care about the absolute intensity of SceneColor (for example, a blur), simplifying custom HLSL and saving some performance. Or useful for non-color UserSceneTextures (for example, mask, matte, modulation, offset, or ID textures), where pre-exposure scale is undesirable. Pre-exposure scale can be manually reapplied via custom HLSL if needed on specific inputs or the output.

bEnableDisplacementFade

uint8 UMaterial::bEnableDisplacementFade

Enables fading out and disabling of dynamic displacement in the distance, as displacement becomes unnoticeable

bEnableExecWire

uint8 UMaterial::bEnableExecWire

bEnableMobileSeparateTranslucency

uint8 UMaterial::bEnableMobileSeparateTranslucency

Indicates that the translucent material should not be affected by bloom or DOF. (Note: Depth testing is not available)

bEnableNewHLSLGenerator

uint8 UMaterial::bEnableNewHLSLGenerator

bEnableResponsiveAA

uint8 UMaterial::bEnableResponsiveAA

Indicates that the material should be rendered using responsive anti-aliasing. Improves sharpness of small moving particles such as sparks. Only use for small moving features because it will cause aliasing of the background.

bEnableStencilTest

uint8 UMaterial::bEnableStencilTest

Selectively execute post process material only for pixels that pass the stencil test against the Custom Depth/Stencil buffer. Pixels that fail the stencil test are filled with the previous post process material output or scene color.

bEnableTessellation

uint8 UMaterial::bEnableTessellation

Whether tessellation is enabled on the material. NOTE: Required for displacement to work.

bForceCompatibleWithLightFunctionAtlas

uint8 UMaterial::bForceCompatibleWithLightFunctionAtlas

Indicates that this material is safe to use with the light function atlas:

• texture coordinates are manipulated in a way that works.
• world position and depth are not used in the graph or do work with the atlas. Forces all deferred lights to go the fast batched lighting code path (no screen shadow mask).

bForwardBlendsSkyLightCubemaps

uint8 UMaterial::bForwardBlendsSkyLightCubemaps

bForwardRenderUsePreintegratedGFForSimpleIBL

uint32 UMaterial::bForwardRenderUsePreintegratedGFForSimpleIBL

bFullyRough

uint8 UMaterial::bFullyRough

bGenerateSphericalParticleNormals

uint8 UMaterial::bGenerateSphericalParticleNormals

Whether to generate spherical normals for particles that use this material.

bHasPixelAnimation

uint8 UMaterial::bHasPixelAnimation

Whether the opaque material has any pixel animations happening, that isn't included in the geometric velocities. This allows to disable renderer's heuristics that assumes animation is fully described with motion vector, such as TSR's anti-flickering heuristic.

bIsBlendable

uint8 UMaterial::bIsBlendable

Allows blendability to be turned off, only used if domain is PostProcess

bIsFunctionPreviewMaterial

uint8 UMaterial::bIsFunctionPreviewMaterial

true if Material is the function preview material used in the material instance editor.

bIsMasked_DEPRECATED

uint8 UMaterial::bIsMasked_DEPRECATED

true if Material is masked and uses custom opacity

bIsMaterialEditorStatsMaterial

uint8 UMaterial::bIsMaterialEditorStatsMaterial

true if this is a special material used for stats by the material editor.

bIsPreviewMaterial

uint8 UMaterial::bIsPreviewMaterial

true if Material is the preview material used in the material editor.

bIsSky

uint8 UMaterial::bIsSky

Unlit and Opaque materials can be used as sky material on a sky dome mesh. When IsSky is true, these meshes will not receive any contribution from the aerial perspective. Height and Volumetric fog effects will still be applied.

bIsThinSurface

uint8 UMaterial::bIsThinSurface

Indicates that the material should be rendered as a thin surface (i.e., without inner volume). Only used by Substrate materials. Enabling ThinSurface will disable subsurface profiles.

bIsTranslucencyVelocityFromDepth

uint8 UMaterial::bIsTranslucencyVelocityFromDepth

When true, translucent materials that write velocity will calculate it only based on the written depth and camera movement. This can be useful for translucent volume raycasts which write pixel depth offset and want to calculate velocity based on the output depth.

BlendableLocation

TEnumAsByte<EBlendableLocation> UMaterial::BlendableLocation

Where the node is inserted in the (post processing) graph, only used if domain is PostProcess

BlendableOutputAlpha

uint8 UMaterial::BlendableOutputAlpha

If this is enabled, the blendable will output alpha

BlendablePriority

int32 UMaterial::BlendablePriority

If multiple nodes with the same type are inserted at the same point, this defined order and if they get combined, only used if domain is PostProcess

bNormalCurvatureToRoughness

uint8 UMaterial::bNormalCurvatureToRoughness

bOutputTranslucentVelocity

uint8 UMaterial::bOutputTranslucentVelocity

When true, translucent materials will output motion vectors and write to depth buffer in velocity pass.
