UeMeshStandardMaterial

A ready-to-use material with built-in lighting support (ambient, point, directional, spot) and texture handling.

Currently handles up to 1 directional light, 8 point lights and 8 spot lights. Only 1 directional, 1 point light and 1 spot light can cast shadows simultaneously.

NOTE: Most properties listed below are fully implemented in sh_ue_standard. Some advanced maps like bumpMap, envMap or lightMap are still in development.

🧾 Material Properties

Property	Type	Description	Default
color	color	Base color of the material.	c_white
emissive	color	Emissive (self-illuminated) color of the material. This color is added to the final pixel color, independent of scene lighting.	c_black
emissiveIntensity	float	Multiplier applied to the emissive color.	0
metalness	float	How much the material looks like a metal. Non-metallic materials such as wood or stone use 0.0, metallic use 1.0.	0
roughness	float	How rough the material appears. 0.0 means a smooth mirror reflection, 1.0 means fully diffuse.	1
aoMapIntensity	float	Intensity of the ambient occlusion effect.	1
bumpScale	float	How much the bump map affects the surface.	1
normalMapScale	vec2	How much the normal map affects the surface.	[1, 1]
displacementScale	float	How much the displacement map affects the mesh.	0
displacementBias	float	Offset of the displacement map values.	0
lightMapIntensity	float	Intensity of the light map.	1
envMapIntensity	float	Intensity of the environment map.	1
envMapRotation	vec3	Rotation of the environment map (Euler angles).	[0, 0, 0]
flatShading	boolean	Whether the material is rendered with flat shading.	false
fog	boolean	Whether the material is affected by fog (Linear and Exponential are supported).	true

🧾 Textures

Property	Type	Description	Default
textures.map	UeTexture	The main diffuse/albedo texture.	undefined
textures.emissiveMap	UeTexture	Texture used to modulate the emissive color.	undefined
textures.alphaMap	UeTexture	Texture used to control the alpha (transparency) per pixel.	undefined
textures.ormMap	UeTexture	Packed texture for Occlusion, Roughness, and Metalness. Color channel mapping: R = Ambient Occlusion, G = Roughness, B = Metalness.	undefined
textures.normalMap	UeTexture	Normal map for adding surface detail.	undefined
textures.displacementMap	UeTexture	Displacement map for deforming the mesh.	undefined
