The most powerful cloud rendering service for Light Tracer Render

As we all know, 3D rendering is the process of creating two-dimensional images from a 3D model. The generated image is based on a combination or mix of multiple data sources such as color, texture, and material. Rendering is used in advertising, animation, jewelry design, and architectural 3D visualization.  Rendering is considered to be a creative process, very similar to photographing or cinematography because you use lighting, choose material behavior, camera view, and as a result, you get a realistic image. In the process of 3D rendering, 3D models are converted to 2D images with either photorealistic or close to real 3D effects. Rendering a single object or scene can take anywhere from a few seconds to several days.

Various technologies are used to achieve a photorealistic look. For example, ray-tracing is a technology for creating realistic lighting, reflections, and shadows, providing a high level of authenticity.  To create a photorealistic 3D image, you need skills of a graphics designer, a powerful computer, and, of course, professional software. What can be an ideal tool for a beginner or even a professional may not be suitable for another artist. Nevertheless, there is a great new software for photorealistic 3D rendering, which is suitable for both professionals and beginners, which is Light Tracer Render. 

What’s Lightracer render?

Light Tracer is a physically based GPU renderer, available as a both commercial product for Windows and macOS, and as a free browser-based service. Light Tracer Render imports models in standard 3D formats including OBJ, FBX, Collada, and glTF, and CAD data in STEP/IGES format and Rhino’s 3DM format. The software supports the Disney Principled material model widely used in other DCC software, and comes with a library of over 300 readymade PBR materials. Although initially designed for HDRI-based lighting, it is increasingly supporting other lighting workflows. Render features include render passes, post effects, filmic tonemapping, and CPU and GPU denoising. Being based on WebGL 2.0, the software is hardware-agnostic, working with both AMD and Nvidia GPUs: Light Engine says that it will run on “almost on any GPU produced after 2012-2013”. According to our knowledge, currently, it is the only ray tracing renderer working inside a Web browser (client-side). 

With Light Tracer you can always expect high-speed computation of realistic images. You can see the result close to the final at any stage of the work. The powerful engine achieves almost real-time performance. When changes are made during rendering, they are immediately visible in the Light Tracer viewport. This means that you do not need to wait for the final render to see the results of changes.

It would not take much time to understand how to use the product. First, you need to download a 3D model from the Internet or create it using any 3D modeling tool and add it to the Light Tracer. After that, you need to choose materials for each part of the 3D model. You can use default materials or customize them for your needs. The app likewise supports adding texture maps (albedo, metallic, roughness, emission maps, normal and roughness maps). Finally, choose a background, environment map, and set up light sources. And just wait a bit till the final quality image will be ready.  

Highlights of Light Tracer render

For product visualization, this renderer has shadow and reflection catchers, to help integrate rendered 3D objects into photographic backplates or solid-color backgrounds. Moreover, it has a mode for rendering caustic effects based on path guiding and better handling of shadows cast by transparent and translucent objects. Handling of coated materials like car paint and varnished wood has also been reworked, with the old clear coat model replaced by a new physically correct layered model. Let’s explore some in details: 

  • Caustic Mode/Path Guiding: A technique that guides light paths during rendering based on an estimate of incoming radiance. Path guiding can make the convergence faster than unaltered path tracing in complex light transport phenomena, such as caustics.
  • Transparent Shadows: If shadow rays hit semi-opaque objects, they will be attenuated and keep traversing until they either encounter an opaque object on their way to the light or reach the light itself.
  • Mesh Emitters/IES Profiles: The improved ray tracing engine performs direct sampling of arbitrarily defined mesh lights. That significantly reduces the shading noise and is especially useful when rendering architectural and interior scenes. IES profiles, that are used to describe the angular distribution of the emitting light, are now also supported.
  • Physically-Based Dielectric Coat: The coating model was reworked, thus allowing to model custom materials like car paint, glazed metal, lacquered wood, and ceramics.

Moreover, the workflow is very convenient, which offers  the options to store and switch between camera views; to hide objects from the render camera but allow them to continue to contribute to scene illumination; and a modeling widget for adding 3D primitives to a scene, primarily intended for mesh lights.

And most recently, Light Engine has released Light Tracer Render 2.2 officially with new features in the update include a physical sun and sky system based on the Hosek-Wilkie model, also supported in render engines like OctaneRender and Blender’s Cycles renderer. Light Tracer Render also now supports PBR materials following the specular-glossiness workflow, as well as the more common metallic-roughness workflow, automatically converting parameters on import. In addition, the update adds support for material layers and a new physically plausible bloom post effect.

Regarding the Pricing and system requirements, the desktop version of Light Tracer Render 2.2 is available for Windows 10+ and macOS 10.15+. New perpetual floating licences cost $99; rental costs $9/month or $84/year $72/year. The online version is free and works in any browser that supports WebGL 2.0: Light Engine recommends Chromium-based browsers like Chrome or Edge.

iRender- Best cloud renderfarm for Light Tracer render

On the official website, the developer says that Light Tracer can run almost on any GPU produced after 2012 – 2013. In particular, it works fine on NVIDIA GeForce 600 series or higher and AMD Radeon RX 200 series or higher. Also, Light Tracer runs on integrated GPUs, such as Intel HD Graphics 4000 series or higher, Intel Iris Graphics, AMD Radeon Graphics, and Apple M1. At the same time, the rendering software can utilize unique features of modern NVIDIA GPUs (if available in the system) to run GPU-accelerated AI denoising. To run CPU-based denoising implemented with Intel Open Image Denoise, you need a CPU with SSE 4.2 support. If your local PC is not powerful enough and you are looking for a high speed cloud Rendering service for Light Tracer, then dont worry,  you are in the right place!
