With the increasing need for 3D visualization in architecture industry, it gets more important to choose the most suitable rendering software for your project. It may be difficult as you tend to think about a couple of factors. One of the most common questions may be “can the software help show my ideas in renderings with expected quality?” Besides, there would be another inevitable concern: “is it affordable?” To minimize the influence of price when choosing the best software, here are eight free 3D rendering software for your reference.

Pricing: Free

OS: Windows, macOS, Linux

 

Thinking of the best free 3D rendering software, Blender is, without doubt, among the first ones brought to mind. Although it is free, Blender has comprehensive tools for 3D visualization from modeling, rendering to post-processing and even animation. To create perfect 3D renderings, it contains two built-in rendering engines: EEVEE and Cycles. Specifically, the GPU-accelerated engine Cycles allows users to view the rendering effect quickly and directly.

In addition, Blender supports to use various third-party renderers, such as LuxCoreRender, V-Ray, Indigo Renderer, etc. These listed renderers are also free but powerful tools. LuxRender is an open-source renderer that is recommended officially by Blender team. It can also work with SketchUp, 3ds Max, Cinema 4D and other major 3D software. With a free 30-day trial, V-Ray provides support for fast rendering. It is especially suitable for 3D rendering of interior design owing to its great effects of global illumination. Indigo Renderer is also a software with varieties of lighting types for models of different spaces. Besides lighting, it contains a material editor which helps maximize photorealism with rich sorts of materials. Moreover, it can save hours for rendering projects by the preliminary setting of materials and lighting.

 

SketchUp Free

In addition to SketchUp free renderer, there are also some excellent plugins that can be used in this best free rendering software, like V-Ray, Lumion LiveSync, SU Podium, etc.

As mentioned above, V-ray is an efficient real-time rendering program especially suitable for interior design. When using SketchUp, V-Ray plugin can make it smooth to create and adjust elements in layers as well as the whole layout. For landscape or exterior design, there is another excellent real-time rendering program Lumion LiveSync. Enabling its plugin, you can import your SketchUp 3D model to the Lumion environment instantly without any interruption while rendering. If you want to share your work via online channels, US Podium can be a good helper. This rendering plugin was specifically designed to be used with SketchUp. It allows users to change complex shapes during the process and adjust settings for lighting and colors after the completion of rendering. It is easy enough for professionals and amateurs to use, and more advantages are to be discovered by yourself.
