In today’s digital age, architects worldwide are constantly using this latest technology to present their designs. It’s becoming an integral part of design because it provides countless benefits for modern designers. Not only it is the perfect way to communicate your idea but also allows us to fix the problems before they ever occur in reality. Compared with traditional hand drawing, 3D rendering is an efficient way to bring the conceptional design to an entirely new level by addressing incredible lifelikeness and beauty. Hence, it greatly persuades potential clients to expedite the final decision process.

Nowadays, we can finish a few images within a couple of days. The advanced technology is truly improved our work quality. But as we enjoy the convenience, there are some factors we should pay attention to, especially when you have a hard deadline, because to create a beautiful rendering is quite difficult. Before you start working on 3d rendering, you should know the basic information about rendering production so as to better arrange the schedule. Read on this to find out what are the factors that will influence the rendering time.

What factors affect Rendering Time

What factors affect Rendering Time

In the basic term, if your rendering takes a very long time because your computer specification is low and all the things are not optimizing well in your 3D scenes. Other than that, there are many other factors that should take into consideration when intended to figure out the basic principle of rendering production. Let’s take a look at the factors.

Hardware configuration

It’s quite easy to understand that the rendering will process faster in the high-performance computer than in the low-performance computer. There are many multi-core processors available to help speed up the computer rendering time. In this case, the CPU is the most important hardware that powers your computer, which is capable of providing sufficient Wattage. In general, before you start working on the rendering, make sure your computer is in good condition with optimized facilities.

Reflection and Refraction

Reflection and Refraction

Speaking of the rendering process, it’s inevitable to mention these two factors. Reflection indicates how light bounces off surfaces and refraction how light goes through surfaces. There are tricky parts when producing the rendering. If there are too many reflections or refraction, it will damage the realness of the images. In order to create a good image, it takes lots of time and manual skills to balance the reflection and refraction.

The complexity of your scene

Complexity refers to the number of polygons in your scene and how many different texture and material that are used in the rendering. Bear in mind that if the model isn’t finished and it requires you to model the space based on the reference image, which will greatly increase the workload as we have to invest more time to finish the missing parts. In order to save time, ask your client to provide the completed model as possible as they could, and avoid using too many different models in one scene.

Shadow

It’s widely accepted that there are two types of shadows in the 3D program, which are depth map and ray traced. If you’re looking for a quicker rendering time, the depth map is the best choice for you. When you using the depth map, be careful about the resolution and artifacts.

Raytraced renders one pixel at a time. Even the time for raytraced is much more than the depth map, it is capable of producing a high degree of visual realism.

How to shorten Rendering time

How to shorten Rendering time

As we have listed some of the factors that are affecting the production time that is involving in create 3d rendering. What can we do to make some improvements and expedite production?

Materials

In order to create a realistic touch, subsurface scattering is the common way to enhance the realness. But as you know the more materials applied in the image, the more time will take. Prior to adding material, you should decide whether it’s needed, especially when you are in the middle of a big deadline.

Geometry

Bear in mind that when a render start, you are able to see everything in your computer, from nodes to model, from texture to shadow, from landscape to terrain. If the geometry is too much detailed and your 3d scenes are too slow to load, it’s suggested that to optimize your scene. Try to focus on the important parts that will appear in the frame. If there are some areas that are not intended to show in the camera, feel safe to ignore those parts.

Hardware

The best way to reduce the rendering time is to get some fast hardware pardner. From time to time, to upgrade your computer to a higher level. Do forget to install CPUs on your computer. With the advent of cloud computing, the rendering process can be faster and easier. As an old saying goes, should well prepare your equipment first before working.

Lighting

When adjusting the lighting, you should think clearly about what you want to achieve. Reflection, refraction, ray shadow… whether they are necessary to be used in the rendering. All the setting depends on the projects. Raytraced can be turned off if you want to save your time. When you optimizing the rendering of the lighting, there are a few things that need to consider. Control the light bounces and balance the time. Turn off the ambient occlusion if it’s not necessary.

Briefly, there are many important factors affecting the rendering production time, but this article only gives you the basic idea. The time varies based on different project type, design, complexity, and space. As we mention above, more details mean more time. If you have a hard deadline for your project, it’s wise to leave more time for modification and correction.
