There are so many renderers available out there, and how does an artist know what to choose? Essentially, renderers really do the same thing. However, they work differently will give different results. Below is a breakdown of what the different renderers offer, not reviews, so you can decide which renderer is right for you.
This article is difficult to put together, and as a result, there is a lot of information to digest. Indeed, I hope this will be a highly used resource. My goal was to create a document to help artists decide which renderer is best for their work while presenting only facts… no opinion… so that users can compare. This comes with a lot of terminologies of which you must have a basic understanding.
Then a bit more about each 3D rendering engine with some videos. Note : This is a living document. We are focusing on rendering tools that we sell at Toolfarm to help our customers make the choice. By the same token, as we add new tools to our store and products are updated, we will update this article.
We will try our best to keep it updated, nonetheless, some information may not be fully correct or may be out of date. Note: Pricing and system requirements are accurate as of the publishing of this article.
We will keep this document updated when we get around to it. Please check for current versions. Think of the central processing unit, or CPU, as the brain and control center of your computer. The CPU is based on single cores so it works on one bit of data at a time.
The GPU is designed for parallel processing so they can work with a lot of data at once. In contrast, a GPU is composed of hundreds of cores that can handle thousands of threads simultaneously.Import or create a proxy mesh asset and V-Ray will automatically generate a set of material slots, making it easier to manage materials.

I was thinking that If redshift is really that good, maybe I can sell most of my team render PC and just invest in more GPUs, so here we go.
So let's take a look at the next comparison. Oh and I removed some of the Redshift watermarks to avoid image attachment limit. Wow, I didn't expect Redshift to be this good. Where you will see a huge difference in speed is if you test an indoor scene like in a room only lit by sun light coming in though a window. Arnold is well know for not being able to do secondary bounces of GI very well.
Even the creator says this. It's not bad if you never run into that situation where you need secondary GI bounces. I'd test a fully textured indoor scene only lit by sun coming though a window and see what you get. If you want to make a test scene to let others take a bash at here they might be able to get better quality with redshift with shorter render times.
V-Ray Next: Smarter rendering with the New Adaptive Dome Light
I'm not saying I would do it, but there are a lot of fans of redshift here. Cycles might even get thrown in there. There are some scenes here if you would like to throw them in arnold and see what times you get I think it would be interesting to have another render engine thrown in. Though the big thing I have with Arnold is their render farm license makes it more expensive to do any rendering with them on a farm.
Even for a local in house farm it can be a lot. Supposedly Arnold GPU is real and might be released soon. They've been talking about it and releasing teases for well over a year and I have to wonder if this is just around the corner. In which case, it will be interesting to see what the differences are in render time. Archived This topic is now archived and is closed to further replies.

My Support Cases.Last week I wrote about Working with Arnold Shaders in Maya and talk a bit about how mental ray was discontinued in this version. This article expands on that. I'm not advanced enough yet in Maya to just figure it out on my own, but with a few Google searches, I realized that mental ray was no longer available and I found a work around with Arnold.
The problem was that the tutorial used a MIA material. I was making a green glass bottle and learned how to do the same effect with Arnold. Not a big deal in the grand scheme. However, I had another solution that I could have made happen instead. I could have installed mental ray. I'm glad that I chose to figure it out in Arnold, since it's the direction that Autodesk has taken Maya, however, I just want you to know that you do have another option. Customers who need to scale their rendering will be able to choose the renderer that best supports their needs, whether it is mental-ray, Arnold V-Ray, Renderman, Octane, Redshift or another third party renderer.
Read more. There are different levels of use that will either allow you to get mental ray for free… or for a fee if you're doing full Maya sequences and network rendering. If you need to buy mental ray, it's a bit on the pricey side and is a yearly subscription, unless you have one of NVIDIA's pro graphics cards, where it's less.
Download free mental ray for M aya. As a brand new user to Maya, this change comes at a great time for me. I won't feel bad when I spend a year learning mental ray and it is suddenly not the default renderer. I can learn Arnold straight away. If you're a long time user of Maya, this may be frustrating to you.
Some people don't like change. Honestly, you're best to learn how to do everything you would do with mental ray with Arnold for Maya. Solid Angle has some resources to make this changeover as easy as possible for the seasoned Maya user. Therefore, you should find it quicker and easier to achieve photo-realistic results with Arnold due to its simplified workflow and physically accurate nature.
Solid Angle has a python script mrShadersToArnold.Depending on what the final product is, a 3D artist will need a render engine to turn their 3D scene into a completed 2D image.
It can be quite an intensive job for you PC and can take several hours depending on the scene. How you render is calculated and eventually turns out is reliant on your render engine.
In this article I will discuss three of the most popular render engines on the market right now. Hopefully it can give you an idea of the pros and cons of each one and figure out which is a good starting point for you.
Arnold Renderer was first conceived in Then called RenderAPI by Marcos Fajardo who wanted to build a render engine that used ray tracing to calculate the final results. This method is regarded as one of the most accurate methods of calculating lighting in a scene. This is also known as unbiased rendering, whereas biased rendering will bounce less light paths and approximate the difference between them. This often gives quicker render times but can cause small lighting errors.
In recent years the visual difference between the two has become smaller and smaller. So while an unbiased render engine does give the most realistic result mathematically, a biased render may not look much different at all.
This allows you to quickly render approximations of your final image. With this you can visualise how certain textures and lighting will interact together in your final render without having to wait hours to see the results. Due to its popularity it was eventually bought by Autodesk in Corona is by far the youngest engine on this list. But has come a long way in that short amount of time and quickly has become regarded as a professional level engine used by many studios.
First starting development in as a student project in Prague, it soon joined a partnership with Chaosgroup just 8 years later in Arnold, as previously mentioned, uses unbiased rendering path tracing which is very good for getting perfect results of lighting that are always replicated from render to render. This can decrease render times while making minimal difference to the final result, apart from some complex lighting caustics.
Check out this article for a bit more info. Like Arnold, Corona also has an interactive GPU rendering option to quickly view approximations of your final result. It also comes with a plethora of other useful plugins and features, like real time post processing effects in the render frame window or buffer and even the ability to change your lighting mid render using the interactive light mixing tool.
It also comes with a small material library that you can use to instantly bring elements of your scene to life, or as a base template to build from. But one of Coronas biggest drawback at the moment is that it only works in 3ds Max and Cinema 4D. V-Ray boasts the strongest pedigree of any render engine on this list, with almost any 3D artist being able to tell you what it is. Formed in in Bulgaria by Chaosgroupit is known for its incredible versatility and wide array of CG options.
It uses a ray tracing biased method for calculating scenes and includes an option to render on both the CPU and GPU at the same time, allowing you to get a production quality render in less time than an engine that is purely CPU based. And like Corona, is has a long list of features to help you process your final output and improve render times.
VRAY vs Octane Render: the challenge of 3D rendering engines
V-Ray also has real time post processing effects such as lens artefacts caused by dust direct lighting, and even a tool to simulate a rolling shutter. These features allow you to make your renders look more like a real world photograph. Although usually the advantage of working in CGI is that you can avoid these imperfections.
V-Ray is used by a large range of studios producing Hollywood films. It is also compatible with almost any 3D software you can think of from SketchUp to 3ds Max and Maya, and everything else in between!Since the release of V-Ray 3. You may have also noticed that V-Ray has gotten much faster by default.
In Depth: 3D Renderers (Updated 8 April 2020) #3drenderer
In fact, many of our users have discovered that their old scenes typically render faster and cleaner, simply by removing their previous settings and switching to the new defaults. In the same way that machine learning makes choices based on what is learned about a specific problem, V-Ray has been adopting learning techniques for analyzing a scene as it is rendering.
V-Ray's analysis results in a faster, cleaner render. For example, with the introduction of Variance-based Adaptive Sampling we eliminated the need to set individual subdivisions on materials and lights, or even camera effects like depth of field. This makes it possible for users to render scenes with a large number of light sources, without affecting render times. Also, a new improved Adaptive Lights 2 technique is coming in our next release more on that later.
A dome light is a spherical or hemispherical light that is often paired with a high dynamic range image HDRI of the environment. This type of image-based environment lighting has been a staple in CG rendering for years. Although image-based lighting has improved over the years, it still involves a lot of sampling, especially for interior scenes. However light typically enters interior spaces through small openings like windows and doors and only a small portion of the dome light actually contributes to the image, making the sampling of the dome light with HDR image not very efficient.
As a workaround, you could add Skylight Portals near openings like doors, windows, and skylights that help direct light samples. To avoid this problem, we built a smarter dome light based on a similar concept as Adaptive Lights. Now, the new Adaptive Dome Light uses the Light Cache calculation phase to learn which parts of the dome light are most likely to affect the scene.
It automatically figures out which portions of the environment to sample and which ones to ignore. This makes it much easier to set up and much more efficient. This is because the Adaptive Dome Light concentrates its efforts in the right spots making it not only more accurate, but faster as well. In some scenes you might not notice a difference in the lighting, but in scenes such as this, the difference is easy to spot.
Many factors can affect the overall speed gains that this feature can give you. Here are a few examples of different types of HDRIs and scene types.
Render times are highly dependent on the number of rays and samples needed to create a clean image. The new Adaptive Dome Light brings intelligence to one of the most frequently used lighting methods in CG today. Want to see how it'll speed up your renders? Download a V-Ray trial.
