This post talks about “Best 3D Render Engine – CPU & GPU Renderers”.

How do you make a photorealistic image or a short animation?

For me, it starts with an idea. Then I make 3D models, rig them, add textures, lighting, visual effects, and the final step would be rendering.

The rendering process will generate an image or a sequence of images from 3D models by means of computer software. This computer software is often called a 3D render engine or renderer (sometimes rendering engine or rendering software).

A variety of 3D render engines are available on the market for different 3D modeling software. I will look at the most popular and best 3D Render Engine in the industry.

What is a 3D Render Engine?

If I have to define,

A 3D render engine is the software or a plugin that performs the calculations needed to generate a final image from a 3D scene. In other words, it takes the 3D models as well as camera, texturing, lighting, and shading data and turns them into an image.

What is a 3D Render Engine used for?

3D render engine is used in various industries. For example, architecture, simulators, video games, visual effects for movies and television, and design visualization.

Rendering techniques and types

A 3D render engine uses specific methodologies as well as special hardware to render an image. In terms of rendering technique, 3D renderers typically use one of below:

  • Rasterization.
  • Ray tracing.
  • Path tracing.

Besides, based on speed and the expected outcome, rendering engines offer different types of rendering. That is:

  • Real-time rendering.
  • Non-real-time rendering.

Choosing the best 3D Render Engine for your need

When choosing the right 3D render engine for you, there are several factors to take into consideration. 

  • Compatibility: Does it work with your 3D software of choice?
  • Hardware: Is it a CPU or GPU-based render engine?
  • Feature-set: Does it have the features you need?
  • Cost and Licensing: Does it cost an arm and a leg or is it free? Perpetual license or subscription?
  • Learning Curve and Support.
  • User Community: Is the render engine’s community large and active?

CPU or GPU Render Engine?

In terms of hardware, 3D render engines take advantage of the processing power of the computer’s CPU or GPU or both to perform the calculations.

  • CPU-based render engines typically can handle bigger and more complex scenes. They can be slower in rendering speed, but more produce accurate results compared to GPU-based render engines. On top of that, CPU renderers have been around for a longer time. So they can have more features and better support.

Some popular CPU render engines are Corona Renderer, Arnold Renderer, and RenderMan.

  • On the other hand, GPU-based render engines generally have a lot faster rendering speed. This is thanks to the GPU’s parallel processing nature. Plus, GPU-based render engines offer better accessibility and scalability for 3D artists and designers. Since GPUs are less expensive, thus easier to add up or upgrade to the rendering system.

Some popular GPU render engines are Redshift and Octane Render.

However, it is the trend today that developers will expand their render engines to support both CPU and GPU rendering. Right now, there are only very few 3D render engines that are purely CPU-based or GPU-based. As far as I know, Corona as CPU renderer and Octane as GPU renderer are two examples.

Best 3D Render Engine – CPU & GPU Renderers

Plenty of 3D render engines are available on the market. It can be a software package’s proprietary render engine, a plug-in, or a standalone software.

However, there are still some most popular and best render engines in the industry, which 3D artists and designers commonly use.
