汽车外饰材质


汽车外饰材质分为两部分。其中有100个是今天发布的,它们都是完全程序化的,每个都有.sbs图表文件。

首批:

  • 汽车油漆材质(MDL)
  • 用于汽车,摩托车和自行车的橡胶轮胎胎面
  • 金属和陶瓷覆盖的格栅,铬,轮辋,制动器和底盘
  • 半透明和发光材质专用于纹理车前灯和尾灯模块

在这批为专业人士设计的新内容中,每种材质都包含广泛的可编辑参数:

  • 美化完成的特效和过程驱动表面等方面。这些帮助设计师和专家们精确复制真实世界的制造细节,就像橙皮汽车漆面。
  • 生命周期的演变和基于环境的风化。这些参数模拟材质的老化,添加划痕和磨损等元素。游戏设计师可以整合基于背景例如泥土,灰尘和雪等制作动画。
  • 设计和图案的生成。Substance材质的表现与生成器相似:它们能够让汽车设计人员在样式和设计上同时反复操作。甚至可以添加专属的2D图案作为输入。游戏艺术家能够做出无数的纹理变化-而不是对它们建模。


汽车油漆

汽车油漆是必不可少的:它几乎覆盖了整辆车的车身。

用于保护和装饰,水性丙烯涂料分层覆盖,总厚度约为100μm(0.1㎜)。

涂层过程由三个步骤组成:
  • 首先,车身准备。然后施加底漆以确保适当的油漆粘附。
  • 接下来,应用底涂层。该涂层包含颜色和特效的视觉特性,通常我们称之为油漆的一种。在汽车工业中,底漆通常分为三类:固体,金属和珠光涂料。


除了颜色以外,固体涂料没有闪光的特效。金属涂料含有铝片,可以产生闪闪发光的颗粒特效。珠光涂料包含“珍珠”的特殊涂料。这些涂料使完成的漆面色彩闪耀,有助于创作出颜色的深度。珠光漆料可直接掺入底漆或者透明涂层下面的中间涂层。

  • 最后一层是抗紫外线透明涂层。这一步不是强制性的,但是可以用于形成有光泽的透明层。

今天可以访问6种最常见的漆料。控制参数,如底涂层金属薄片,尺寸,方向,颜色和形状。

这些漆料需要复杂的定义来复制油漆层的组合。因此,除了.sbs图表外,我们还为每种漆料提供了MDL着色器。都可以从Substance资源库下载,你可以在Substance Designer中利用着色器可视化调整漆料 - 以及任何其他具有MDL集成的软件,例如Vray。

无论你是否拥有自己的着色器,或者使用没有MDL集成的实时引擎工作,这都不需要从通常的途径切换。你可以使用.sbs图表的贴图并且自定义每层油漆的属性。例如,通过调整专用透明涂层法线贴图来驱动顶涂层上的橙皮特效。

640 (2).gif

我们为油漆添加了光线老化参数来增加划痕,污垢和潮湿。关于背景可以添加一些轻微的细节,当创建“一定情境的”最新的全路模型漂亮的画面。或者在Substance Painter中应用老化特效在汽车模型上结合自然风化与汽车油漆成智能材质。

橡胶轮胎

我们的团队创建了一个庞大的橡胶轮胎生成器的数据库,用于纹理汽车轮毂。我们复制了赛车,城市和全地形车以及摩托车和自行车的轮胎胎面。

640 (4).gif

每种轮胎材质都可以用作生成器,包括可调整的参数,如橡胶纹理的颗粒,它的光泽度以及修剪线,倒刺和螺栓等制造元素。

640.gif

找不到你需要的花纹图案?只需设计自己的图案并将位图或者SVG直接输入到材质中即可。

你可能需要更多的真实感通过再现甚至动画化冲击在高速公路上,一条泥泞的道路或者一个冰雪冰冻的湖泊上行驶几英里。

640 (5).gif


轮辋的基础知识

为了完成车轮纹理,我们添加了轮辋生成器材质。本周,可以使用基本的钢轮辋和金属化塑料轮罩。

这些材质融合了建模和纹理。这样,可以在工作的时候同时处理形状和材质。这个系统可以让你在涉及建模资源前尝试反复操作很多次以获取理想的设计。

微信截图_20180709101801.png

此外,现在可以生成自定义资源通过使用更多的形状和材质变体包括颜色,表面光洁度,生锈,灰尘和油渍来个性化模型。


车牌生成器

640 (6).gif

轮辋不是能够使用材质生成器重新创建的唯一部分。我们创建了Substance材质。允许复制来自欧洲,美国,日本和澳大利亚的车牌。这些印版配备了大量的参数来添加自定义模板和位图,文本编辑器,以及自定义铆钉,添加铁锈或者芯片涂漆的功能。


照明元件和反光镜

640 (7).gif

前照灯光线和反光镜也是汽车外饰纹理的关键元件。并且为了看起来逼真,通常需要大量的建模。此外,这种类型的建模往往都是一次性工作,因为很少的元件可以从一个模型转移到另一个模型。

微信截图_20180709102000.png

为了帮助优化工作,我们创建了基础材质工具以及现成的前照灯生成器。

微信截图_20180709102022.png

方法:将每种材质分成不同类别,像透明塑料和铬反光镜(以便处理3D资源细节),或者重建前照灯和材质的所有细节的组合以节省建模时间。还想要更真实吗?我们添加了发光元件材质,以便精确控制灯和LED。


金属和铬

金属和陶瓷制动材质

微信截图_20180709102057.png

采用这种方法,我们创建了纹理金属零件的基础材质 - 金属和陶瓷制动旋翼,以及铬和金属格栅。


金属格栅

微信截图_20180709102123.png

获取各种金属格栅图案,用于前散热器进气口和侧勺

但这仅仅是一个起点!想要创建自己的图案?获取.sbs图表然后添加自己的程序魔法到任何材质中。

SUBSTANCE SOURCE AUTOMOTIVE MATERIALS: EXTERIOR 1
Nicolas Paulhac on June 14 2018 | Substance Source, Release, Design

Today we’re following up on last week’s release of prototyping materials with more than 100 assets dedicated to car exteriors.

Are you making a real production model? Are you working on a racing game? The fully tweakable procedural materials faithfully reproduce the style and behavior of real-life materials.

Car Exterior Materials

The car exterior materials are divided into two parts. 100 of these are released today, and all of them are fully procedural, with .sbs graphs are available for each one.

This week:

Car paint materials (MDL).

Rubber tire treads for cars, motorbikes and bicycles.

Metallic and ceramic covers for grilles, chromes, rims, brakes, and chassis.

Translucent and emissive materials dedicated to texturing headlight and taillight modules.

In this batch of new content designed for professionals, each material includes a wide range of editable parameters:

Cosmetic finish effects and process-driven surface aspects. These help designers and viz experts to work with precise reproductions of real-world manufacturing details, like the orange peel on car paint.

Life-cycle evolution and context-based weathering. These parameters emulate the aging of the material, adding elements such as scratches and abrasion. Game designers can incorporate and even animate variations based on the environments such as mud, dirt, and snow.

Design and pattern generation. These Substance materials behave like generators: they enable car designers to iterate on form and design at the same time. It's even possible to add your own 2D patterns as inputs. Game artists will be able to generate countless variations in texture - instead of modeling them.

Car Paints

Car paint is the absolute must-have: it covers almost the whole body of the vehicle.
Used for both protection and decoration, water-based acrylic paint is applied in layers, with a total thickness of around 100µm (0.1mm).
The coating process consists of three steps:
First, the body is prepared. A primer is then applied to ensure proper paint adhesion.

Next, a basecoat layer is applied. This coat contains the visual properties of color and effects and is usually the one we call paint. In the automotive industry, base coats are commonly divided into three categories: solid, metallic, and pearlescent pigments.

Solid paints have no sparkle effects except the color. Metallic paints contain aluminum flakes, which create a sparkling and grainy effect. Pearlescent paints contain special pigments referred to as "pearls". Those pigments impart a colored sparkle to the finish, which helps create the depth of color. Pearlescent paints can be incorporated directly into the base coat or into a mid-coat below the clearcoat layer.

The last layer is a UV-light resistant clear coat. It is not mandatory but may be applied to form a glossy, transparent layer.

Today, get access to the 6 most common categories of car paint. Get control over parameters such as basecoat metallic flakes, size, orientation, color, and shape.
These paints require complex material definition to reproduce the combinations of paint layers. So, in addition to the .sbs graph, we’ve delivered each asset with an MDL shader. By downloading both from Substance Source, you’ll be able to visualize and tweak the paints with the shader into Substance Designer - and any other software with an MDL integration, such as Vray.

Whether you already have your own paint shader, or you work in a real-time engine with no MDL integration, there’s no need to switch from your usual pipeline. You can use the maps from the .sbs graph and customize the properties of each layer of paint. For example, you’ll be able to drive the amount of orange peel effect on the topcoat layer by tweaking a dedicated clearcoat normal map.

We’ve added parameters of light aging for the paints to enable the addition of scratches, dirt, and wetness. You can add subtle details about the environment while creating “in context” beauty shots of the latest all-road model, or apply aging on vehicle meshes combining natural and weathered car paint into smart materials in Substance Painter.

Rubber Tires

Our team created an extensive library of rubber tire generators for texturing vehicle wheels. We reproduced tire treads of cars for both racing, urban and all-terrain vehicles as well as motorbikes and bicycles.

Each tire material works as a generator and includes tweakable parameters such as the grain of the rubber texture, its glossiness, and manufacturing elements like trim lines, barbs, and studs.

Can’t find the tread pattern you need? Just design your own and input the bitmap or SVG directly into the material.

You may need to add more realism by reproducing or even animating the impact of driving a few miles on the freeway, a muddy road or a snowy frozen lake.

Rim Basics

To complete wheel texturing, we added rim generator materials. This week, get access to basic steel rims and metalized plastic wheel covers.

These materials blend modeling and texturing. This way, you can work on the shape and materials at the same time. This system lets you try out more iterations to get the right design before involving modeling resources.

In addition, you can now generate customized assets to personalize your models with a greater amount of shapes and material variations including color, finish, rust, dust, and grease stains.

License Plate Generators
Rims are not the only part you‘ll be able to recreate with material generators. We’ve created Substance materials allowing you to reproduce license plates from Europe, the USA, Japan and Australia. These plates come with a wide list of parameters to add custom stencils and bitmaps, a text editor, and the ability to customize rivets, add rust, or chip paint.
Lighting Elements and Reflectors
Headlights and reflectors are also key elements for car exterior texturing, and often require extensive modeling in order to look realistic. Furthermore, this type of modeling tends to be a one-time job because very few elements can be transferred from one model to another.

To help you optimize your work, we’ve created a toolset of base materials as well as ready-made headlamp generators.

Our approach: either separate each material into different categories, like transparent plastics and chrome reflectors (in case you’re dealing with a detailed 3D asset), or recreate all the details of the headlight and material combinations to save modeling time. Want to get more realistic still? We’ve added emissive component materials so that you can have precise control over lamps and LEDs.

Metals and Chromes
Metal and Ceramic Brake Materials
Following this approach, we’ve created base materials for texturing metal parts - metal and ceramic brake rotors, for example, as well as chromes and metal grilles.

Metal Grilles
Get access to a wide range of basic metallic grille patterns for front radiator intake and side scoops.

But this is just a starting point! Want to make your own pattern? Get the .sbs graphs and add your own procedural magic to any materials.

Well, that’s all for this week. Download the free materials from this release on Substance Source. Stay tuned - the next hundred exterior materials are coming Thursday, June 21 with more exterior materials.
