V-Ray 5 : Setting up your Initial 3ds Max scene, IPR in the viewport using CPU or GPU, VFB layers and LUT files




With V-Ray 5 Viewport IPR, building up a 3d scene has become a lot faster, as there's hardly a need to test render lights and materials.

Note: IPR(Interactive Production Rendering) in the Viewport works with CPU, GPU or both.

To start, ensure to setup your 3ds Max scene properly first:

1- Before starting to model and/or create lights in a scene, ensure to have these parameters set up properly and accordingly.

2-Also, go to the Customize toolbar and choose the Preferences option.

3-Under Gamma and LUT tab, turn on the Enable Gamma/LUT Correction, and set it to 2.2.

4-Under Files tab, if you happen to be working on a large file that's taking too long to save, you can increase the Backup Interval (minutes) to 30 or higher, and choose to Compress on Save.
Compressed Max files are automatically reduced to half or less of their original size, when saved.  

Files Tab 



5-Under General tab, increase the Scene Undo Levels to about 500. This will give you the flexibility to undo (Ctrl+Z) up to 500 levels, if required.

6-To configure the viewports, simply click on the + text and choose to Configure Viewports

Configure Viewports



7-Under the Layout tab, select a suitable viewport layout. Users can also right click on a specific layout and choose the viewport.
Note: When creating the sunlight object, it's best to choose a four viewport layout.

10-Next, open the Render Setup dialog (F10). Under V-Ray tab, set the Image filter as VRayLanczosFilter.

Under Color mapping parameters, set its Type to Exponential. This will reduce overly burnt areas in the image, and give a more realistic look to the render.
Set, the Gamma value to 2.2.

Under Mode, set it to, Color mapping and gamma. This will ensure what is seen in the VFB is consistent with what is saved into your hard drive.

Note: If you choose another Color Mode type, your saved renders will look either darker or brighter from what is seen in your VFB. 

Scenes saved in earlier versions of 3ds Max may require merging in a completely new 3ds Max scene with the above Color Mode type, in order to override the problem.

Lights

1-To create the sunlight, ensure to have all four viewports in display (zoomed out).
Go to the Create panel and select the Lights button.
Under Photometric list, choose the VRay type.

Choose VRay light 



2-Next, select the VRaySun button, followed by clicking and dragging it in the Front viewport to create it.

VRayLightMix


7-Next, go the Render Setup dialog (F10). Under Render Elements tab, click to Add the VRayLightMix element.
Add the VRayLightMix element
  
Note: By default, it is set to Group by Instanced lights. This option displays all instanced lights in the scene as one Layer in the VFB.

If you want the flexibility to manipulate the instanced lights individually, simply choose the option to Group by Individual lights.

V-Ray Frame Buffer layers


8-Open the V-Ray Frame Buffer dialog and add the Filmic tonemap Layer.

9-Under its Properties Type, change it to Linear. You should also start seeing changes in the Viewport IPR.
Note: You may need to tweak some of its default Properties as materials are added in the scene.  

Filmic tonemap: AMPAS Type 



10-Also, add a Lookup Table Layer, and load the LUT file under the name of, 3DCollective_sRGB_Agfa_Futura_03Hard.cube .
Disable the function to, Convert sRGB Space first and enable the Save in image option.

Note: This LUT file worked well for this scene. However, feel free to use another LUT file, if desired.

12-To add a bit of haze to the sunlight, open the Environment dialog (8). Under the Atmosphere rollout parameters, add the VRayAerialPerspective shader.

Under its General parameters, set the Visibility range (in meters) to about 2000.0. The Atmosphere height to about 100 and enable the function to Affect environment rays.

These values worked well for this scene. However, feel free to try different values, if desired.

V-Ray: Vray is a rendering engine that uses global illumination algorithms, including path tracing, photon mapping, irradiance maps and directly computed global illumination.
Furthermore, it is used as a commercial plug-in for third-party 3D computer graphics software applications such as 3ds max, Maya, Houdini, Blender, Nuke, etc,  for visualizations and computer graphics in industries such as media, entertainment, film and video game production, industrial design, product design and architecture.

3ds Max: Autodesk 3ds Max, formerly 3D Studio and 3D Studio Max, is a professional 3D computer graphics program designed to create 3D animations, models, games and images.
In addition, it has modelling, animation and movie effects capabilities, frequently used by video game developers, TV commercial studios and architectural visualization studios.
3ds Max also features shaders, dynamic simulations, particle systems, plug-ins, and much more, with its own scripting language.

Adobe Photoshop: Photoshop is a powerful raster based graphics program produced by the Adobe Corporation. 
It is widely used for a variety of photo/image editing purposes worldwide. The program has a huge number of filters, functions, plug-ins, scripts, etc.
In addition, there is a huge online support for this software, and countless online sites with tips and tutorials.
Finally, there are readily available books, online/college courses, and its full documentation at Adobe.com


3d Visualiser works within the realm of 3d visualization, a sector of the Computer Graphics Industry (or CGI) that is primarily concerned with the visual presentation of design concepts and ideas. And a company within the 3d visualisation sector offers to its customers (among many things) 3d Visualization Services.


3d Rendering: Is the process of converting the three dimensional (3D) data seen in a 3d scene into 2D image/s (rasterized).
The rasterization process include, the rendering parameters, the rendering engine, lights, 3d models, textures, shaders, and other effects.
3D renders can be a sequence of animated objects/effects/cameras, or a single frame with a still camera and object/s.
Some of the articles, Videos and Tutorials depicted here will take you through the process of rendering.

Photorealistic RenderingIs the Process or Art of making a typical Computer Generated Image/render (CGI) look indistinguishable from a real photo.
To achieve this, users often need to possess the skills and the"eye" to appreciate good photography, cameras, composition, lighting, shaders, materials, 3d modelling, rendering and have some post-production skills.
Some of the articles, Videos and Tutorials depicted here will help you achieve truly photorealistic renderings.  


Post-ProductionIs the process of creating effects or/and results after/post the main process.
This terminology can be used to describe the results (post-production) of main processes such as 3d renderings  and/or filming a scene.
The post-production often takes place in applications such as Photoshop, After Effects, Nuke, etc. 
Some of the articles, Videos and Tutorials depicted here will take you through the process.

Architectural Rendering, or architectural illustration/Visualization, is the art/process of creating two-dimensional images or animations depicting the attributes of an architectural design, while using state of the art applications such as, Autocad, 3ds max, VRay, Cinema 4d, Blender, Maya, Corona, Photoshop, etc
Some of the articles, Videos and Tutorials depicted here will take you through this amazing process. 


TexturesIs a term often used to describe photographed  2d images to be later used in a toggle of a shader or procedural map.
Textures can be used in the Diffuse toggle, Reflect, Glossy effects, Bump, Displacement, etc.

Some of the articles, Videos and Tutorials depicted here will take you through the process of applying textures.

MaterialsIs a term often used to describe maps, textures,procedural maps or shaders, depending on the context the term is being used.
Some of the articles, Videos and Tutorials depicted here will take you through the process of applying materials.


Procedural materialsIs a term often used to describe maps with editable/proprietary parameters/functions.
Some of the articles, Videos and Tutorials depicted here will take you through the process of applying procedural materials.


ShadersIs a term often used to describe complex materials with functions and procedural maps created for a specific purpose.
Some of the articles, Videos and Tutorials depicted here will take you through the process of applying shaders.

Architectural Rendering, or architectural illustration/Visualization, is the art/process of creating two-dimensional images or animations depicting the attributes of an architectural design, while using state of the art applications such as, Autocad, 3ds max, VRay, Cinema 4d, Blender, Maya, Corona, Photoshop, etc
Some of the articles, Videos and Tutorials depicted here will take you through this amazing process.

Studio Lights are fundamental in the process of creating appealing images/renders.
The overall lighting determines not only the brightness and the darkness; but also the tone, mood and the atmosphere of a scene.
Hence the importance to control and manipulate the lights accordingly, in order to fully capture the textures and the vibrancy of your objects.
By distributing the shadows and the highlights accurately, you can achieve truly appealing images/renders.
Some of the articles, Videos and Tutorials depicted here will take you through the process of creating and applying Studio Lights.


Interior design is the art and science of enhancing the interior of a building or/and a space to achieve a more aesthetically pleasing and comfortable environment for those using the space.

An interior designer is someone who plans, researches, coordinates, and manages such projects. Interior design is a multifaceted profession that includes conceptual development, space planning, site inspections, programming, research, communicating with the stakeholders of a project, construction management, and execution of the design.
