Reduce Rendering Times in 3Ds Max

What is 3Ds Max?

Autodesk 3Ds Max is a 3D modeling software used for architectural visualizations, product modeling, character development and animation. So, whether you are an architect, a product designer or an illustrator, 3Ds Max is a great software option for you.

3D software packages, including Autodesk 3Ds Max, generally convert 3D models into CGIs through a rendering process. Even though, rendering process is the provider of all the cool stuff we see that is generated with 3Ds Max, as you know, rendering in 3Ds Max may take too long sometimes. It is frustrating especially since there’s nothing much to do with your system while it renders your work.

A lot of things may be contributing to these long rendering times from low-end hardware to large files. If you are a creative that uses 3Ds Max, this must be relatable for you and for the newbies, hang in there. Long rendering times reduce efficiency every time.

Hence, faster rendering times can be a huge relief for creatives that use 3Ds Max as a major tool. With little tips here and there, faster rendering times can be achieved, even without changing your PC’s hardware. How great is that? Here are a few of those tips on how to render faster on 3Ds Max!

1. Use Low Poly Models

When time is a priority over quality, rendering low poly models can be a great option rather than high poly models. High poly models require enormous CPU calculations. As a result, more calculation leads to longer rendering times.

To check your polycount, you can click the “+” sign on the top right of your viewport. After that, you can go to “x view” and tick the “show statistics” option. Or you can press 7 directly.

2. Turn Off Displacement

Displacement maps work to complement bum maps. They give an illusion of depth, aiding realistic render output. Although using displacement maps add a lot of value to quality, displacement maps are not necessary where time is the essence. Turning off the displacement map and rendering in the geometric bump map can help achieve shorter rendering times.

To turn off displacement, you can check the “rendering/render set-up” sections and scroll down until you find the “displacement” option. When you untick the box, the displacement will be turned off.

3. Reduce The Render Output Resolutions.

Smaller resolutions for your output mean less work for your CPU. It is one of the easiest ways to have rendered images. 2000 x 1500px is an average resolution size. Rendering in a lower resolution will be faster. With higher resolution, it would be vice versa.

4. Reduce The Reflections and Gloss in Your Scenes

Having reflections in your render scenes increases total rendering times. This is because glossy elements need to be cleaned or denoised to the last detail to be as glossy as portrayed. For renders where these reflection effects do not do much, turning them off would do you a big favor by reducing the rendering time.

5. Use a Denoiser

With the denoiser function turned on, 3Ds Max decreases rendering times significantly. The denoiser as the name implies removes the grain in your render output. With denoiser on, you do not need to render all the passes before you get a desirable output. With a denoiser, at render pass 30, your render is ready to go.

Denoisers work directly with render engines, so they can be easily turned on accordingly when rendering.

6. Reduce the Number of High-Resolution Textures

For average renders, 2k textures do a pretty awesome job. Using 4k textures in most cases will be unnecessary and will also create more work for your system. Remember that more work means more time. Tone down the 4k textures and see how you reduce your render times.

2k textures might as well be high-resolution textures in some context and so, based on the scope of your project, reducing the high-resolution textures is totally up to you.

7. Scale Down Scene Detail

For large scenes where the camera is at a considerable distance, precision detailing may not be necessary as these details will not be visible in the render. However, these detailed models will contribute to the render time.

This also applies to close up shots. Objects not in the camera viewport can be deleted to lighten the model and render faster in 3Ds Max.

8. Copy Components as an Instance.

Here’s what happens when you copy as an instance; your computer transfers all the detail from the copied model to another position while still occupying the disk space of just one entity.This is very helpful when working with populations and duplicates. The only disadvantage is that you cannot alter the properties of the copies.

To copy components as an instance; right click on your object and go to “clone”. Then, tick the “instance” option and now, you can copy it as an instance.

9. Optimize Your Model

Model optimization can reduce render times in 3Ds max. There are a couple of plug-ins that help to optimize models. They ultimately make the workflow in 3Ds Max faster and of course, reduce render times. These plug-ins are optimizing modifiers.

For example, you can check out Turbosmooth Modifier, Optimize Modifier, ProOptimizer Modifier and MultiRes Modifier for reducing your rendering times.

Rendering in 3Ds Max takes a lot of time and over the years, discussions around how to reduce render times have always come up. We have highlighted a few optimization tips to achieve faster render times and a smoother workflow without having to improve your hardware in this post.

We have also not considered the quality of the rendering here, just the render time. With the tips that we have put up, if speed is more primary than quality for your project then, you would find this information useful.
