VRayIES
VRayIES lights are often used to recreate existing artificial light profile distributions, for interior scenes.
Companies such ERCO and Color Kinetics have a host of exiting IES light profiles ready for download:

To create a VRayIES light, use some of the steps described earlier, and refer to my other tutorial about, setting up your Initial 3ds Max scene.
https://jamiecardoso-mentalray.blogspot.com/2020/09/v-ray-5-setting-up-your-initial-3ds-max.html
Followed by selecting the VRayIES button, clicking the cursor in the Front/Left viewport , and dragging it down to create it.
Right click to exit light creation

Once the VRayIES light has been created (with its target facing downwards), users can disable the Targeted function, to move the VRayIES light.
Most of the VRayIES parameters are self-explanatory. The following discussion will focus mainly on the most important ones.
 |
| <VRayIES light parameters> |
Enable- It enables the light to be turned On, or Off.
Show distribution- It shows the distribution of the IES light in the viewport.
IES file-This toggle allows users to locate and plug IES light profile.
IES web profiles are based on a real-world light distribution. IES 14 is one of the most popular light profiles used to create patterns of pools of light on the floor, and walls.
Note: IES 14 is included in the book resources.

To preview the IES distribution in the shaded viewport, simply click on the User Defined text, and choose the Light and Shadows option.
Followed by choosing to, Illuminate with scene Lights.
 |
| < User viewport option to Illuminate with scene Lights> |
 |
| < Results of Illuminate with scene Lights in the viewport> |
If you happen to have a good graphics card, enable the V-Ray Viewport IPR (Interactive Production Rendering) to display a fast and accurate preview of the final render in the viewport.

| < User viewport option to choose the V-Ray Viewport IPR > |
Affect diffuse- This function determines whether the IES light will affect the diffuse color of objects, or not.
Enabled, by default.
Diffuse contribution-This function controls the intensity of the lights on the diffuse color of objects.
Default value, 1.0
Affect specular- This function determines whether the IES light will affect the specular/glossiness of objects, or not.
Enabled, by default.
Specular contribution- This function controls how much the IES light will affect the specular/glossiness of objects.
Default value, 1.0
Use light shape-This function controls how the shape of the light will be factored in to process the shadows and the illumination.
For shadows only, is used by default.
Override shape-If chosen, it disables the IES profile shape, and enables functions such as, Shape, Height, Width, Length and Diameter.
Override Intensity-This function controls how the IES light intensity will be used.
Rescale-This function matches the light intensity defined by the user.
Replace-This function recalculates(multiplies) the intensity based on the IES distribution.
Intensity type- This function determines the units of the light intensity.
Intensity value - This function controls the intensity of the IES light.
 |
| < VRayIES light Intensity value set to 2500.0> |
 |
| < Render result of Intensity value set to 2500.0> |
 |
| < Intensity value IES power set to 17800.0> |
 |
| < Render result of Intensity value set to 17800.0> |
To light up a fairly spacious scene it is recommended to create multiple ies lights. I often copy/instance (Ctrl+v) ies lights across the scene to speed up the rendering process substantially.

Shaders: Is 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.
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.
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 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 Rendering: Is 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-Production: Is 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.
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.
Verified View/s: Is an accurate Photomontage of a proposed design/building, using the Guidelines for Landscape and Visual Impact Assessment (GLVIA3).
Photomontage in 3d Visualization: Is the process of incorporating a 3d object/design/building into a 2d image/photo, while matching the camera angle/settings, position and the overall lighting depicted in the 2d photo.
This laborious process often requires the usage of a 2d and a 3d application.
To create an accurate Photomontage/Verified View, the 3d Visualizer/specialist needs a: 3d context model to plot/plan the shots; a photo of the location in question; the survey data; camera information; a 2d and a 3d application to create the Final Verified View/s .
Some of the articles, Videos and Tutorials depicted here will take you through the process.
Planning Applications: These can be used to find out whether a proposed development is likely to be approved by the planning authority, before substantial costs are incurred developing a detailed design.
Planning Permissions: Is the legal process of determining whether proposed developments should be permitted. Responsibility for planning lies with local planning authorities (usually the planning department of the district or borough council). The legislation, policy and guidance that underpins planning in England can be found on the government's National Planning Practice Guidance
A 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.
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.
