17 Proven Tips to Speed Up Making 3D Renderings

You respect deadlines. Whether you are a 3D artist, a team leader, or a client who use 3D visualizations for your needs. You concern whether or not 3D renderings will be done in time. Let me tell you, your concerns are very reasonable, because missing deadlines may cause negative feedbacks or other reputational losses.

The bad and the good feedback

Use these 17 tips (proven on hundreds of various projects) to get 3D renderings faster.

1. Use stock 3D models and textures.

This is a tip for 3D artists and team leaders. But clients can participate in this process and use this suggestion too.

3D artists don't need to make all of 3D models and textures from scratch.

Here are some samples of stock 3D models which already created by various 3D artists around the World:

  • Bathroom accessories and fixtures.

  • Interior and exterior plants, trees, flowers.

  • Interior and exterior furniture.

  • Light fixtures.

  • Cars.

You can just download or buy them. There are many web platforms with stock 3D models. Here are some of the popular:

Of course, if you need to create some specific furniture, accessories or something else, and you cannot find a 3D model of this objects on a 3D stock platform, it's not the case. In this case, a 3D model of this object should be created individually. However, in many cases, a downloading or purchasing of 3D models on a stock platform will give you time and even cost economy.

For example:

1. You work on interior 3D renderings of a living room. Probably it's possible to download or purchase 3D models of a TV and interior accessories on stock platforms rather than spend hours with 3d modeling of these objects.

2. You work with exterior 3D rendering. Perhaps, you shouldn't care about creating 3D models of trees and exterior plants with every single leaf and branch. You also shouldn't care about creating 3D models of cars, exterior furniture, and in many cases about 3D models of surrounded buildings. You can find all of these 3D models on stock platforms.

BTW: you can use the Good Free 3D Model of Buildings in your architectural or other kind of scenes. This model is done by 3D artist AndreyAE.

You also can buy or download free textures for your projects on the following platforms:

3D artists need seamless textures so that they didn't have a seam effect if tiled. To make them they use various image editing software and spend their time and effort. Good news, many of the texture stock platforms mentioned above have seamless textures of various materials. So you can download and use them without additional edition.

If you are a client who uses 3D rendering services, please keep in mind that you can review 3D models and textures on stock platforms and ask or suggest your 3D artists use them in 3D renderings they make for you.

2. Keep and use old project files.

This is a tip for 3D artists, and team leaders. If you are a client and got working files from your 3D artists, you can use this tip too.

Old 3DS Max files

Never delete your project files even if you did them 10 years ago.

You can use objects, materials and render presets taken from these files in your next projects. So it may speed up your further work.

If you think about how to get free space on your HDD, you can use either method provided below:

  • Archive your old work files by using archive apps, such as WinRAR, etc.

  • Move your old projects to an external or cloud storage.

3. Use the symmetry.

This tip is for 3D artists.

A lot of things in the real world, such as buildings, furniture, electronics has a symmetry. It means that to make 3D models of these objects 3D artists can model a half, a quarter, and even in some cases 1/8 part of an object. After that, they can get the rest of it as a symmetrical part.

Look at this 3D rendering of the complex historical building.

Architectural 3D Rendering of the historical building

Though it isn't quite symmetric the most part of the building has a symmetry axis.

Our team did not model the whole building. We did a half of it, and after we used the mirror 3DS Max function to get the rest. After that, we added parts which aren't symmetrical. Imagine how many time we saved.

Look at this 3D rendering of the electronic device.

3D product rendering of the control unit

Though due to LEDs, inscriptions and the junction line it is not quite symmetrical, without these details it has the several symmetry axes.

It actually allowed me to make only 1/8 part of this box, after that I used the symmetry modifier in 3DS Max to get the whole box. And then I added LEDs and inscriptions.

4. Use plugins and scripts.

This suggestion will be interesting for 3D artists and team leaders, because usually, they control scripts used in making of 3D renderings.

Plugins and scripts allow us to:

  • Speed up some of the operations.

  • Add an additional functionality.

  • Make some of the processes more convenient.

3D Studio Max, Maya and many other 3D modeling and rendering applications have the ability to install plugins and scripts. Here are some of the scripts for 3DS Max:

1. Bevel lite. Allow us to easy create objects with bevels, especially wooden parts, such as a tabletop.

2. Copy/paste. Though 3DS Max doesn't have important functions such as copy and paste, you can install this script and use them. Use this script to copy a selected object from your scene and paste it into another scene. The script uses a max file in a system folder to keep copied objects. So, you can use this script in 2 ways:

  • Select and copy an object, open another scene, paste an object.

  • Run 2 instances of 3DS Max (by running the application twice) and open scenes in each 3DS Max. Select and copy an object in a scene of one of 3DS Max, and paste it into a scene of another instance of 3DS Max.

3. Instancer. Creates instances from selected objects.

4. Fast Housing. Allow us to quickly create house by using parametric 3D modeling tool.

5. Use 2D or 3D Cad files.

This is a tip for 3D artists, team leaders, and clients.

If a 3D artist or a team will use CAD files, provided by clients, it will speed-up make 3D renderings.
