Guide for reducing rendering times at Blender 3D

Blender is perhaps the best thing to happen to the computer-animation industry since the creators of the software (Pixar) created the first mainstream computer-generated cartoon (Toy Story 1). Since its creation, Blender has become more sophisticated than the HUD of a Boeing 747 and has the support of users worldwide. It also works on almost any PC or laptop. The sad part is that its power comes at a cost. The rendering times are a little longer than with programs like Toon Boom Harmony, Adobe Character Creator and so forth. Here are a few tips on how to reduce rendering times.

You Need a Rendering Service

The best and most powerful way to reduce your rendering times with Blender is to use a Blender render farm. People are going to tell you that you can buy high-end computers and your own servers, but they are still not as fast as a rendering service. The level of optimization and processing power available at rendering farms is other-worldly.

Testing With Lower Settings

For your final creation, use the top settings. However, if you are just testing your work, then lower the resolution, lower the image quality, and lower the render settings. Even on medium settings, the result is still pretty good, and you can still identify any potential problems with your content.

On a similar (albeit obvious note), you don’t have to render an entire scene to test it. For example, if you have just added a few adjustments to the lip sync in a scene, then isolate that scene, use the start and end function, and render out just that little bit.

Lower The Final Settings

If you are compiling the finished product on a different editor, then you need to use the top stats. Perhaps even render your content on PNG images so that you lose as little as possible when you create your edit on a different program.

However, if you are rendering your final-use product, you don’t have to pick “Lossless.” For example, if you are uploading something to YouTube, you can set it to MPEG 4, H.264, and then set it to “Perceptually Lossless.” This is ideal for YouTube since it dramatically lowers file sizes and makes it easier for YouTube to correctly optimize your content to work on YouTube. Remember that no matter how good your content looks, YouTube is going to butcher the quality with their optimizing software.

Transfer perceptually lossless and lossless content over to an editor and do some heavy edits, and the differences may eventually show. Upload losses and perceptually lossless to YouTube, TikTok, Twitter, etc., and they will always look the same because a third-party piece of software is going to optimize and compress your content in a manner that is outside of your control.

Hiding Layers and Combining Layers

You can hide a few layers if your renderings are going too slowly, but this is not possible if you are rendering out your final product. Turn off the preview settings on Blender because your computer will have to work towards creating the content and creating the previews. If you are not sure how something will turn out, render out just a few seconds rather than rendering out the entire scene. Do not run other processor-intensive programs while you are rendering. This means leaving your torrent downloads until later, or delaying your file transfers from hard drive to hard drive until Blender has finished rendering.

Consider allowing Blender to use more RAM, and perhaps upgrade your RAM if your design process is choppy or slow, and your renders are taking too long. Though again, the fastest and most efficient way to render out your product is through a rendering service.
