LuxCoreRender
What LuxCoreRender is
LuxCoreRender is a physically based rendering engine that models light to create realistic images. It is designed for artists seeking visual accuracy while retaining physical correctness, and is free for personal and commercial use under the Apache Public License v2.0. It uses OpenCL and/or CUDA across supported CPUs and GPUs; the project says performance scales linearly with the number of supported devices. Material options include matte, glossy, Disney principled, metal, glass and car paint, alongside procedural and image textures, bump mapping and normal mapping. Lighting can use emitters, environment light, IES data, HDR environments, or a physical sun and sky. Dynamic scene editing is supported, and renders can be paused, saved and resumed later, including on another computer. BlendLuxCore is its Blender extension, with version 2.11.1 officially supporting Blender 4.5 LTS and 5.2 LTS. The C++ and Python APIs can be used in open source and commercial applications. Python wheels and standalone command-line and GUI applications are also available. It supports Windows, Linux and macOS.
