Factors that affects the rendering performance in 3D software

Generating images by computer or rendering is a resource intensive process that often requires the use of multiple machines working together to complete the job in time. The process of generating a digital image from predefined digital models using a computer is affected by many factors and generally takes considerable resources like time, processing power and energy.

In this article, we will review the different factors affecting the rendering times, from hardware to resolution, settings and render engines, special rendering performance in 3D software.

1. Hardware

To be able to make proper 3D renders you will need to have an adequate PC. However, there is no way around this, and no matter how good you might be at rendering, you can’t get the most out of it without a good workstation. Over the years the hardware has improved for both consumers and producers, so even if much more computers are available, the new quality requirements still use cutting edge technology, parallelization is still required.

While working with a scene in CPU rendering, the most important factor is having as many cores as possible, and it does not participate at all in GPU based renderers. Usually the renderers using GPU are faster and nowadays the quality is generally as high as with CPU rendering. Some renderers like VRay can use GPU or CPU to render with the exact same result.

Besides there are lots of other factors like RAM, storage, etc affecting the rendering speed or you can use iRender farm, and take full control of many machines at the same time, easy to use at a reasonable price.

2. Software

2.1. Modeling software

Different software will be differences in the parameter settings affecting rendering times. Some popular software in 3D modeling and animation are Maya, Blender and Cinema 4D, 3Ds max. When the project is ready for rendering, this program will send the task data (scene, frames to render, resolution, exposure values, etc.) to the rendering engine that will do the actual rendering work.

2.2. Rendering engine

The rendering engine is the software component that performs the actual rendering process. Some renderers can give better results at the cost of higher rendering times. Choosing an ideal renderer depends on the specifics of the task at hand and is beyond the scope of the work here, in this document only a quick look to real-world time examples of their differences is taken, to get a sense of scale and to compare their scalability.

3. Resolution

Resolution might be the most important factor since it scales faster than it seems and will compound on all other factors. Usually a certain resolution is needed for certain tasks and cannot be downgraded. Consumers are getting used to high resolutions with full HD being the absolute minimum and 4K a common demand nowadays.

As can be seen in Table above, Resolution and pixel count, the pixel count scales so even though 4K has twice the dimensions of full HD, the pixel count is four times greater.

These are some of the most important things you simply must consider when getting a 3D rendering workhouse. Don’t go all out straight away, consider your current needs to invest your money in a powerful workstation or rent them at iRender farm.
