Tip1: Remember that with Mental Ray the fake reflection is NOT visible in the material slot as preview. You must make a test rendering to see the result. Tip 2: There are many ways to create Chrome. Another way to create Chrome is trough a RAYTRACE material (change standard with RAYTRACE in a new material slot). Tip 2: There are many ways to create Chrome. Another way to create Chrome is trough a RAYTRACE material (change standard with RAYTRACE in a new material slot). But the result is the same as in the standard material. Tip 3: A HDRI image can also used as a fake reflection. HDRI renderings will be explained in other Florence Design Academy. ADD TO COLLECTION.

Welcome to V-Ray for 3ds Max’s official Courseware site. The goal of this courseware is to improve the level of knowledge of V-Ray among its users.

Downloading the scenes and assets for this courseware requires a free Chaos Group account.

Content Overview

The courseware is based on the concept of learning cycles, a proven method for teaching adults. This concept splits each topic into three distinct cycles:

1. Lecture – This introduces the theory of the topic. This is the time to show imagery, discuss theories, make the connection between CG and the real world, and explain what settings do.
2. Demonstration – Topics discussed in the lecture are put into action by the educator. It is important that students do not try to copy what is being shown so they can pay full attention to the demonstration and explanations.
3. Activity – Students gain vital hands-on experience be reproducing what they have seen, and can do their own experiments. This cycle gives the students the chance to try out settings, solve problems, and ask questions.

The courseware provides you with materials for each of the three cycles for every Topic:

1. Lecture – This includes a PowerPoint presentation, and a sample lesson plan to help your preparations.
2. Demonstration and Activity – We provide you with 3ds Max scenes, and Lesson guides. Lesson guides include a sample exercise sequence for the demonstration, and they can be distributed to students. The PowerPoint presentations and Lesson guides can be downloaded separately from the page for each lesson as well as in the Download section of this courseware.

Scenes and assets are packed into a project file. These must be downloaded together to ensure that all textures and other assets will load correctly.

Maps

Maps are bitmaps or procedural textures that are used to give color and other apparent surface characteristics ('textures') to 3D objects in Max.

There can be different types of maps. Some maps wrap images about objects, while others define areas to be modified by comparing the intensity of the pixels in the map. An example of this is a bump map. A standard bump map would be a grayscale image. When mapped onto an object, lighter colored sections would be raised to a maximum of pure white and darker sections would be indented to a minimum of black. This enables you to easily create surface textures, such as an orange rind, without having to model them.

The basic parameters of a shader like diffuse, specular, self-illumination, opacity etc. can be mapped with a bitmap or a procedural texture. Clicking on the small button in front of the color swatch can do this job. Clicking on this button opens a Material/Map Browser. When a parameter is mapped, the small button shows “M”.

Figure 5-4: Shader Basic Parameters

Mapping the diffuse parameter with a bitmap will enable the bitmap to appear around the surface of the 3d object.

The Maps rollout is where you apply maps to the various materials. To use a map, click on the Map button; this opens the Material/Map Browser where you can select the map to be used. The Amount spinner sets the intensity of the map, and an option to enable or disable the map is available. For example, a white material with a red Diffuse map set at 50 % Intensity results in a pink material.

Figure 5-5: Maps Rollout

The available maps in the Maps rollout depend on the type of material and the Shader that you are using. Raytrace materials have many more available maps than the standard material. Some of the common mapping types found in the Maps rollout are discussed in this section.

Material/Map Browser

The Material/Map Browser lets you choose a material or a map. When you click Get Material, the Browser that is displayed is modeless (you can leave it displayed while you do other work). However, when you display the Browser by clicking the Type button, a map assignment button in the Environment dialog, or from a projector light (see Advanced Effects Rollout), it appears as a modal dialog with OK and Cancel buttons.

The Material/Map Browser includes several browse options accessible as radio buttons on the left of the dialog box. The browse options include Material Library, MaterialEditor, Active Slot, Selected, Scene, and New. In order to choose a bitmap image as a map, you click on New, and the Bitmap on the top of the list appears.

UVW Mapping Coordinates

An object assigned a 2D mapped material (or a material that contains 2D maps) must have mapping coordinates. These coordinates specify how the map is projected onto the material, and whether it is projected as a 'decal,' or whether it is tiled or mirrored. Mapping coordinates are also known as UV or UVW coordinates. These letters refer to coordinates in the object's own space, as opposed to the XYZ coordinates that describe the scene as a whole.

Mapping coordinates are used to define how a texture map is aligned to an object. These coordinates are expressed using U, V, and W dimensions, with U being a horizontal direction, V being a vertical direction, and W being depth.

UVW Map Modifier:

UVW Map modifier controls how mapped and procedural materials appear on the surface of an object. Mapping coordinates specify how bitmaps are projected onto an object. The UVW coordinate system is similar to the XYZ coordinate system. The U and V axes of a bitmap correspond to the X and Y axes. The W axis, which corresponds to the Z axis, is generally only used for procedural maps. A bitmap's coordinate system can be switched in the Material Editor to VW or WU, in which case the bitmap is rotated and projected so that it is perpendicular to the surface.

UVW Map Modifier projects the UVW coordinates on the surface of the 3d object. This projection can be done in the following available ways.

• Planar
• Cylindrical
• Spherical
• Shrink Wrap
• Box
• Face
• XYZ to UVW

Primitives, Loft Objects, and NURBS can generate their own mapping coordinates, but you need to use this modifier to apply mapping coordinates to mesh objects and patches.

Unwrap UVW Modifier

How To Create More Material Slots 3ds Max Games

The Unwrap UVW modifier lets you control how a map is applied to a subobject selection. It can also be used to unwrap the existing mapping coordinates of an object. You can then edit these coordinates as needed. You can also use the Unwrap UVW modifier to apply multiple planar maps to an object. You accomplish this task by creating planar maps for various sides of an object and then editing the mapping coordinates in the Edit UVWs interface.

How To Create More Material Slots 3ds Max Free

The Unwrap UVW modifier can be used as a self-contained UVW mapper and UVW coordinate editor, or in conjunction with the UVW Map modifier. If you use Unwrap UVW in conjunction with the UVW Map modifier, it is usually because you want to map the model with a method other than planar mapping, such as cylindrical or spherical mapping. You can animate UVW coordinates by turning on the Auto Key button and transforming the coordinates at different frames.
