Smoke rendered in LuxCoreRender using the BlenderLuxCore integration plugin. Version 2.4 of the physically based open source renderer offers support for the Blender Mantaflow fluid simulation framework.
The LuxCoreRender team released version 2.4 of the physically based open source renderer and added a new CUDA backend for Nvidia GPUs and support for rendering GPUs outside of the core and viewport.
Other changes to the core renderer include thin-film interference to mimic effects such as oil films and soap bubbles, support for LUTs in cube format, and improved scanning and easy caching.
BlendLuxCore, the Blender integration plugin, supports Mantaflow simulations, a new albedo mode for look development and a new library of pre-built architecture models and materials.
A hybrid impartial CPU / GPU render engine, formerly known as LuxRender
LuxCoreRender, formerly known as LuxRender, was restarted in 2018 with a name change, a new project website, a forum and online documentation.
It is a physically based rendering engine with a number of production functions that supports hybrid C ++ / OpenCL rendering on CPUs and GPUs from LuxCoreRender 2.0.
Version 2.0 also reduced the number of DCC tools in which the renderer is integrated: While LuxRender used to have plugins for a number of apps, LuxCoreRender only supports Blender.
New in LuxCoreRender 2.4: Better GPU rendering performance
LuxCoreRender 2.4 includes a number of changes to improve GPU rendering performance, including a new CUDA backend that is described on Nvidia GPUs as "a little faster" than the existing OpenCL version.
The software now also supports out-of-core rendering on AMD and Nvidia GPUs, so that scenes that are too large to fit in the GPU memory can be rendered without traditionally affecting performance.
In addition, the software's material and texture evaluation code has been rewritten so that kernel compilation is only required during installation and not every time the scene settings are changed.
The change makes it possible to use the OpenCL backend as a viewport renderer, although this can increase overall render times for simple scenes: complex scenes are less affected. More details can be found here.
LuxCoreRender 2.4: thin film interference, better light caching, support for .cube LUTs
The new functions of the core renderer include the support of thin-film interferences, which make it possible to imitate real shimmering effects, as can be seen in oil films on water, soap bubbles and heated metal.
It is available in the glass materials from LuxCoreRender and in the universal Disney Principled material.
Workflow and performance improvements include rewriting the ambient light cache, which should result in less noisy images when rendering lighting from lighting portals.
The PhotonGI cache for indirect light and caustics has also been expanded to support lighting groups.
In addition, there are new preset sample patterns for renderings tailored for progressive previews, final quality renderings, and out-of-core rendering.
Pipeline improvements include the support of LUTs in .cube format for the output of color corrections.
BlendLuxCore 2.4: Mataflow support, new albedo render mode for look-dev work
In addition to the changes to the core renderer, the Blender plugin also supports smoke simulations that were generated in mantaflow, the new fluid simulation framework that was added in Blender 2.82.
The update also introduces a new albedo rendering mode that is designed to provide a quick, interactive preview of a scene during the layout of the shot and the development of the appearance.
The new mode, which replaces the native look-dev mode of Blender's Eevee renderer, only shows the albedo AOV of a material, improving interactive performance.
The Blender plugin now also includes a link to an online library of architectural models and materials created by Charles Nandeya Ehouman (Sharlybg) (see video above).
Users can fill interior scenes by adding furniture and ornaments from the library directly into Blender. The assets are available under a Creative Commons Attribution license.
System requirements and availability
LuxCoreRender 2.4 is available under an Apache 2.0 license for Windows, Linux and macOS. BlendLuxCore 2.4 is compatible with Blender 2.82+.
