What are iray and mental ray, and what do they do?
Iray is an NVIDIA 3D rendering application that provides photorealistic, high-quality images for use in design, engineering and architectural visualization. It allows for the production of large images in a fraction of the time normally required, and it is compatible with most modern computer workstations. A complete version of iray includes an integrated modeler, and a complete version of mental ray includes the raytracer.
Iray is based on an open, industry-standard architecture that allows it to be integrated into any workflow. This integration also enables support for an extensive set of NVIDIA products, which can be used in conjunction with iray to extend the system and improve production efficiencies.
How are they different from each other, and which one is better for you?
Iray and mental ray are similar in that they both render images, but that is where the similarities end. In contrast to iray, mental ray comes with a commercial license and non-commercial licenses. Also, mental ray has an open source community that helps to fix bugs and create new features. In terms of the two programs’ performance, iray is a complete lighting solution, while mental ray is better-suited for issuing specific lighting instructions. Because iray relies on the graphics card for rendering, it renders more quickly than mental ray. Mental ray is also slower, but it can also handle a greater number of 3D objects than iray.
Which software is more popular among 3D artists, and why?
Although iray is a newer 3D rendering application, mental ray is still popular among artists because of its long history and large following. This is largely attributable to the fact that mental ray has been around since the mid-1990s, and its parent company, [[NVIDA]], is a well-known computer graphics software developer.
[[NVIDA]] wrote its own implementation of a [[radiosity]] algorithm because their hardware at the time did not support [[ray tracing]]. It was an exact implementation, and it was the most advanced available for many years. Although ray tracing is now used by other renderers, mental ray is still mostly used for rendering with [[NVIDA]] hardware.
While in theory iray could be used for any rendering task, mental ray is specifically optimized for use with [[NVIDA]] GPUs.
Although NVIDA’s original mental ray renderer is still significantly faster than iray in many cases, new features in mental ray 6 and its ability to use recent [[NVIDA]] hardware may make it more attractive for 3D artists as well. [NO JOKE ABOUT THE FACT THAT IT IS]
How much does each program cost, and where can you buy them?
Iray is available for free, but it requires a registration. mental ray is available for both free and commercial licensing options. The full version of iray (required to use the modeler) can be purchased through NVIDIA’s website, while mental ray’s full version can be purchased at CDW (NVIDIA’s authorized reseller).

** The following is a quote from the link posted by “ivanpah” on March 11, 2007 on this article: “Iray for 3ds max is available for free, but it requires a registration.” ** “You must register with NVIDIA to receive the free iray 3ds Max plug-in. Registering will also allow you to download the latest version of iray. In addition, if you register with NVIDIA, you will also receive free updates for a full year to your registered programs in iray. You will also receive information about upcoming developments to iray.” ** “While it is not necessary to register, the registration can be of great convenience. For example, registering allows you to send a message directly from the Help file on the iray registration site. If you register, you can also download the original iray Help file (as opposed to the online documentation), which is of a much higher quality than the online documentation. Both versions of the documentation are available when you register.”
What are the pros and cons of using iray or mental ray in your workflows?
Iray is a very fast rendering solution that allows users to complete projects in a fraction of the time they would take using other solutions. It is also easy to use and set up, although it relies on NVIDIA graphics cards for computing, which can be cost-prohibitive for some people. mental ray offers a complete lighting solution, and its commercial license is well-suited for organizations. However, it can be difficult to maintain and set up, especially for new users.
Cost-effective solution
Iray is a free plug-in available to anyone who downloads and installs the latest version of 3ds Max. This makes it ideal for students and hobbyists on a budget. It features a number of presets that allow users to quickly set up a scene with access to materials, lighting, cameras, etc. The entire process can take less than an hour. Many users report that rendering times are as low as one-fifth of those for V-Ray and other solutions. Iray is also easy to maintain and update, which is convenient for people who might not have a lot of time to manage their workflows.
