In Volume 9 of this 'Transforming Robot Production Pipeline' series, we will discuss the techniques that were used and some of the issues that were encountered during the lighting and rendering of this transforming robot project. We will look at how we went about matching the lighting between our CG and live-action elements, setting up our materials and textures, and rendering all of the passes and other information that our compositing artists will be using during Volume 10 of this series.

We will begin the tutorial by learning the importance of a proper linear workflow whenever dealing with lighting scenarios where realism is of the utmost importance. We will learn how to set up and place light sources within our scene, we will discuss concepts regarding real-world light behavior, and how those principles become very important during the lighting of our scene, as well as many additional topics, tips and techniques that you can put to immediate use in your own studio lighting scenarios.

These videos will walk through the essential tools for creating photorealistic materials. We'll start with establishing our shading toolkit through the various models of simulating real-world light interactions. Then we'll jump into a series of challenging material types, and develop the basic shading networks required to make them happen.

Throughout the tutorial, we'll cover all of the hidden details that are needed to use HDR imagery for lighting in Maya. We'll start with physically based lighting, world scene scale, color management, proper render preview and verification of valid floating point linear color images. Once the rules for using HDR images are clearly laid out, we will take a look at how you can create your own HDR images at home using a DSLR camera, tripod, nodal head and software. Lastly, we'll go over examples of using and editing these images for a variety of indoor and outdoor lighting situations as well as covering light extraction and making HDR kooks from an HDR photo of a light.

We will begin with an explanation of the linear workflow process, and help to clarify exactly why a linear workflow is needed is order to get lighting results that are much more realistic. From there, we will learn the various steps for setting up a linear workflow in Maya, including the use of Maya's Color Management features, gamma-correcting images and textures to be rendered and displayed correctly, maintaining a proper linear workflow during the compositing phase, and many additional tips and techniques that will help you get much more realistic lighting results with significantly less effort.

Having a solid understanding of the features of mental ray is a crucial step toward becoming an efficient and productive rendering artist in Softimage. We will begin our tutorial by learning several methods for simulating realistic indirect lighting in Softimage, such as global illumination, final gather, as well as Importons and Irradiance Particles. We will also explore the use of caustics to simulate the light patterns created as light passes through refractive surfaces. In addition, we will also explore Image-based lighting techniques, camera and environment shaders, utilizing render passes and render channels, as well as many other tools and techniques that will allow you start rendering high quality work for a multitude of projects.

Intended for small-scale productions, this tutorial walks through one lighting and rendering workflow that introduces new tools, techniques, and workarounds. We will exploit the environment-sampling power of portal lights, build a fake GI solution with projected light fields, and use MEL scripts to automate tedious tasks. These methods won't work for every scenario, but they can be very useful tools for the guerrilla CG filmmaker.

The ability to realistically light an interior environment is a skill that is highly sought after in the CG industry. It is a skill that is used very heavily in areas such as feature films, games, and architectural visualizations. This course will explore the entire, step-by-step process of lighting your scenes. We will start by learning how to make sure that our lights are behaving in a way that is physically accurate by utilizing real-world light data in our scenes. From there, we will learn how to incorporate realistic secondary illumination into our scenes, learn how to create physically-accurate materials in Maya, and explore many techniques and workflows designed to help you overcome many of the common issues that you are likely to encounter in your own scenes.

In the world around us, much of the light that we perceive comes from indirect illumination, or light that bounces off other surfaces to illuminate our surroundings. One of the ways that mental ray allows us to incorporate realistic light bouncing into our rendered images is to use global illumination. We will begin this course by learning about the underlying principles of global illumination, and how it relies on photons to calculate the lighting result. From there, we will learn how to adjust photon emission values, incorporating final gather into our global illumination results, saving and re-using global illumination data, override rendered photon results using the render tree, and many other lessons dedicated to explaining the various features and parameters used to control the global illumination result. By the time you complete this course, you will have a much stronger understanding of the underlying principles of global illumination, as well as a better understanding of some the common global illumination pitfalls, limitations, and their solutions.

We'll begin our tutorial by learning how to use global illumination, final gather, and the new Irradiance Particles as well as importons so that you can easily simulate the effects of indirect lighting and quickly render highly realistic scenes. We'll also spend some time going over how you can dramatically increase your rendering speed by saving and re-using indirect illumination data, giving you more time to focus on the creative aspect of the image. We'll also explore how you can use caustics to simulate the light patterns that are created when light passes through refractive surfaces. Then, we'll then take time to explore several specialized mental ray shaders like the architectural materials, subsurface scattering, and ambient occlusion shaders, as well as learn how we can use Render Passes and Render Channels to split our renders into multiple passes for compositing purposes.

In this series of lessons, we will discuss the advanced rendering features found in the 3ds Max mental ray production shaders, and how they can become a valuable part of your production pipeline. We will learn how these production shaders can be used for a variety of purposes, such as adding nearly instantaneous motion blur to our rendered images, we will discuss shaders that allow seamless integration of our 3D art into a live-action plate, as well as production shaders that allow for rapid correction and re-rendering of specific scene elements, as well as discussing several other production shaders. Using these shaders, we now have access to mental ray features that will allow us to render our images faster, with a much higher level of control, and with much higher quality.

In this series of lessons we will discuss a variety of tools and workflows to help improve speed and stability when attempting to render heavy, resource-intensive scenes within mental ray. We will explore several methods for conserving system resources, such as using the command-line to render your scenes outside of Maya, using mental ray render proxies to minimize the amount of memory consumed by your scene files, how to render high resolution images into separate smaller tiles, as well as several other workflows for improving performance and stability within mental ray. Using these workflows, we will be able to dedicate more of our system resources to the rendering of our scene files, and significantly reduce the frequency of any crashing we may experience.
