UberShader for Substrate: Material Pack

Substrate (released as Experimental in 5.3) is a modular principled BRDF shader that will replace UE materials like Default Lit. The UberShader for Substrate Material Pack has been completely rebuilt for Substrate, taking advantage of its next-gen features to better emulate the Arnold Standard Surface, including specular color and IOR, a clear coat vertical layer, a full subsurface scattering implementation using mean free path (MFP) and phase anisotropy, sheen (fuzz), thin-film iridescence, stochastic flakes (glint), as well as familiar parameters from Mega Scans materials such as color corrections, and double roughness sliders from packed maps.

IMPORTANT:

Substate must be enabled in the Project Settings. See the Unreal Docs for instructions.

Epic says of Substrate "You can try out this Experimental feature, but we do not recommend shipping projects with it."

UberShader for Substrate Video Walkthrough

Substrate Master Materials

Five Substrate master materials are provided:

• Uber Advanced Substrate (M_UberAdv_sub) – This is the main workhorse used to achieve a host of looks for opaque surfaces. It contains all of the parameters of an Arnold Standard Surface (see the parameter list in the Technical Details below), minus the Transmission section.
• Uber Advanced Substrate VT (M_UberAdv_Sub_VT) – Same as above, but with support for UDIM mapping,
• Uber Glass Substrate (M_UberGlass_Sub) – A Substrate glass material with rough refractions, tinted glass, and a vertical blend dirt layer.
• Uber Thin Substrate (M_UberThin_Sub) – Substrate emulation of the Two-Sided Foliage material for thin-walled translucent objects such as plants and curtains.
• Uber Layer Substrate (M_UberLayer_Sub) – Two UberShader Substrate slabs layered together with a horizontal blend driven by a packed map. This allows for separate control of the foreground and background material parameters.

Substrate Example Material Instances

All 27 example Material Instances from the original UberShader are included, each translated to Substrate. Additionally, 28 more have been added to demonstrate the new functionality of Substrate. These include examples with glint (snow, sand), thin-film iridescence (house fly, soap bubble), the layered shader (dry and wet dirt, metal and rust, snow and rock, and my favorite, cookie and chocolate chip! Check out the image gallery above for some eye candy.

基材用UberShader：材料包

Substrate（在5.3中作为实验版本发布）是一个模块化的原则性BRDF着色器，它将取代像Default Lit这样的UE材质。 Ubershader For Substrate Material Pack已完全针对Substrate进行了重建，利用其下一代功能更好地模拟Arnold标准表面，包括镜面颜色和IOR，透明涂层垂直层，使用平均自由路径（MFP）和相位各向异性的全次表面散射实现，光泽（fuzz），薄膜虹彩，随机薄片（glint），以及Mega Scans材料的熟悉参数，如颜色校正，以及包装地图中的双粗糙度滑块。

重要事项:

必须在项目设置中启用Substate。 查看 虚幻文档 供指示。

Epic谈到Substrate时说：”您可以尝试这个实验性功能，但我们不建议使用它运送项目。”

基材母材

提供五种基板母材:

• 优步高级基板（M_UberAdv_sub） -这是 用于实现一系列不透明表面的主要主力。 它包含阿诺德标准表面的所有参数（请参阅下面的技术细节中的参数列表），减去传输部分。
• 优步高级基板VT(M_UberAdv_Sub_VT) -同上，但支持UDIM映射,
• 优步玻璃基板 (M_UberGlass_Sub） -具有粗糙折射、有色玻璃和垂直混合污垢层的基板玻璃材料。
• 超级瘦 基材（M_UberThin_Sub) -双面树叶的基底模拟 材料 于植物、窗帘等薄壁半透明物体。
• 优步层 基材（M_UberLayer_Sub） -两块UberShader衬底板分层在一起，由填充地图驱动的水平混合。 这允许单独控制前景和背景材料参数。

基板实例材料实例

包含来自原始UberShader的所有27个示例材质实例，每个实例都转换为Substrate。 此外,还增加了28个来演示基板的新功能. 这些例子包括闪光（雪，沙），薄膜彩虹（房子苍蝇，肥皂泡），分层着色器（干湿污垢，金属和铁锈，雪和岩石，我最喜欢的饼干和巧克力片！ 查看上面的图片库以获得一些眼睛糖果。
