Arnoldis an advanced cross-platform rendering library, or API, used by a number of prominent organizations in film, television, and animation, including Sony Pictures Imageworks. It was developed as a photo-realistic, physically-based ray tracing alternative to traditional scanline based rendering software for CG animation. Arnold uses cutting-edge algorithms that make the most effective use of your computer's hardware resources: memory, disk space, multiple processor cores, and SIMD/SSE units. The Arnold architecture was designed to easily adapt to existing pipelines. It is built on top of a pluggable node system; users can extend and customize the system by writing new shaders, cameras, filters, and output driver nodes, as well as procedural geometry, custom ray types and user-defined geometric data. The primary goal of the Arnold architecture is to provide a complete solution as a primary renderer for animation and visual effects.
Arnold for 3ds Maxis an unbiased, physically based, ray tracing 3D rendering engine. It is the default complex rendering engine that comes along with 3ds Max, and it is one of the most used engines in major productions like Gravity, Elysium, Pacific Rim, Alice in Wonderland, and many others. It excels itself in achieving reliable, good looking, realistic results rather quickly, which can give the user time to spend improving the actual scene, rather than tweaking its settings.

In this tutorial which is a part of " Comprehensive introduction to Arnold for 3ds Max" course , we learn how to approach interior lighting in Arnold for 3ds Max.

Solid Angle SLis the technology company behind the Arnold rendering software, with offices in Madrid and London and customers throughout the world including Framestore, DreamWorks, ILM, Sony Pictures Imageworks, MPC, The Mill, Mikros Image and Rising Sun Pictures. Arnold was designed from the ground up to efficiently raytrace the complex geometric datasets required for feature-length CGI animation and big budget visual effects, while at the same time simplifying the pipeline, reducing the number of passes, minimizing storage requirements and greatly enhancing interactivity for lighting artists.
