This allows you to quickly render approximations of your final image. So while an unbiased render engine does give the most realistic result mathematically, a biased render may not look much different at all.Īrnold recently introduced the ability to use GPU rendering in early 2019. In recent years the visual difference between the two has become smaller and smaller. This often gives quicker render times but can cause small lighting errors. This is also known as unbiased rendering, whereas biased rendering will bounce less light paths and approximate the difference between them. This method is regarded as one of the most accurate methods of calculating lighting in a scene.

It uses a specific method of ray tracing (called path tracing or Monte Carlo ray tracing) that sends many random possible light paths at each pixel then averaging them to find the “correct” final result. ArnoldĪrnold Renderer was first conceived in 1997 (Then called RenderAPI) by Marcos Fajardo who wanted to build a render engine that used ray tracing to calculate the final results.

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.

In this article I will discuss three of the most popular render engines on the market right now. How you render is calculated and eventually turns out is reliant on your render engine. It can be quite an intensive job for you PC and can take several hours depending on the scene. It is the render engine’s job to calculate all the lighting and geometry in your scene and how they all interact with each other and your materials. That means if you buy something we get a small commission at no extra cost to you( learn more)ĭepending on what the final product is, a 3D artist will need a render engine to turn their 3D scene into a completed 2D image.
