KeyShot 3D Rendering

Chapter 2. Understanding Materials and Textures

Now we will learn how to set up and assign materials and how to apply textures to them to create a hyperrealistic look in our models.

In this chapter you will learn:

  • Assigning and editing our materials for our project

  • Understanding the materials' properties

  • Creating our own unique materials

  • Texturing methods

Placing and editing materials


Continuing with our example from the previous chapter, after naming all the parts of the model, our Wacom tablet model is now ready to have materials assigned to it.

Pad

Start by adding a material to our writing pad. Perform the following steps:

  1. Let's start by clicking on the Library icon in our viewport.

  2. Select the material Hard rough plastic – slate grey from the plastics material folder Plastic | Hard | Rough | Classic.

  3. Drag the material from our project window and drop it onto the pad's writing area of our Wacom tablet.

  4. Double-click on the pad to open the project editor.

  5. On the Roughness parameter let's make the value 0.120.

  6. Click on the color swatch from the diffuse channel and change the values for the following parameters:

    • Hue: 240

    • Saturation: 19

    • Value: 52

    • Red: 48

    • Green: 48

    • Blue: 52

This results in the following screenshot:

Under the transparent protective cover and the writing pad of the tablet, we have the case. It houses all the electronic...

Understanding materials and their properties


If we take a look at a real-life tablet, in this case the Wacom Intuos 3, we will notice many interesting characteristics regarding the type of materials that the tablet was built with. For our tablet, we have chosen different kinds of plastic materials, and as you may have noticed, whenever you open the Project Editor window by double-clicking anywhere on our object, there are more properties and preferences available to us. Specifically, there are five categories, with each one having a different effect on the overall look of our scene. In this section, we are going to study the properties of the Material tab and its purpose. In general, each material has its own sets of properties inside KeyShot, and since we are using a hard rough plastic material, there are three major parameters, listed just after the following screenshot:

The following are the three major parameters:

  • Diffuse: This modifier allows us to control the overall color of the material...

How to create materials


We can begin creating a new material in KeyShot in a number of ways. It can be based on an existing material in the library or we can create it from scratch. The following methods will help us understand the possibilities as well as the limitations of some of the materials we use. I also encourage everyone to experiment with different ways of creating the materials on their own.

Whenever we first open KeyShot and import one of our objects into our scene, by default the type of material that is applied to the object is the advanced type, which is a generic material that basically can be used to recreate other types of materials.

The list of the type of materials in KeyShot can be found under the name of Material in the project window. For our purposes we will discuss a few different types of materials that are often used and also the advantages and limitations of each one of them.

These materials are listed in the following section.

Plastics

As we learned previously from...

Texturing materials and methods


To complete our understanding of how to apply realistic materials onto our models, we will need to understand the process of applying textures. Inside KeyShot there are many ways to map an object in order to prepare it for the texturing phase. We previously mentioned the various mapping methods, as follows:

  • Planar X, Y, and Z

  • UV coordinates

  • Box

  • Spherical

  • Cylindrical

By default, when we first import an object to our scene, the UV coordinates method is automatically chosen as the standard mapping solution. UV mapping is often a long and tedious process in which we take a flat 2D image and place it or texture it onto a 3D object. This method is more commonly used by professionals in the entertainment business because of the high demand in quality.

However, the preferred mapping method for most of our needs will be the Box mapping approach. Using this method we do not have to worry about UV coordinates because all the textures placed onto our models will be done through...

Summary


In this chapter, we saw that all the materials can be found by clicking on the Library icon from our viewport. To apply a material all we need to do is select the material we want from the drop-down list and drag-and-drop it onto the model. We can adjust the look of a material by double-clicking on the material and opening the properties window. We have studied the different ways we can texture and apply materials to our models. For most situations, using box mapping is the recommended method, since it gives the best results and avoids texture stretching. Box mapping is also ideal for parametric modeling software such as Solidworks or AutoCAD. UV mapping is mostly used for models that have been mapped with UV coordinates and is often used for models from applications such as 3ds Max or Maya. Labels work as decals or stickers that can be placed onto our models by adding them to the label's tab. This images are normally exported with a transparency or alpha channel from another application...

What is custom duty/charge? Chevron down icon Chevron up icon

Customs duty are charges levied on goods when they cross international borders. It is a tax that is imposed on imported goods. These duties are charged by special authorities and bodies created by local governments and are meant to protect local industries, economies, and businesses.

Do I have to pay customs charges for the print book order? Chevron down icon Chevron up icon

The orders shipped to the countries that are listed under EU27 will not bear custom charges. They are paid by Packt as part of the order.

List of EU27 countries: www.gov.uk/eu-eea:

A custom duty or localized taxes may be applicable on the shipment and would be charged by the recipient country outside of the EU27 which should be paid by the customer and these duties are not included in the shipping charges been charged on the order.

How do I know my custom duty charges? Chevron down icon Chevron up icon

The amount of duty payable varies greatly depending on the imported goods, the country of origin and several other factors like the total invoice amount or dimensions like weight, and other such criteria applicable in your country.

For example:

  • If you live in Mexico, and the declared value of your ordered items is over $ 50, for you to receive a package, you will have to pay additional import tax of 19% which will be $ 9.50 to the courier service.
  • Whereas if you live in Turkey, and the declared value of your ordered items is over € 22, for you to receive a package, you will have to pay additional import tax of 18% which will be € 3.96 to the courier service.
