What appleseed is
appleseed is a free, open source rendering engine for animation and visual effects. It uses physically based global illumination and is designed for individuals and small studios seeking a complete rendering package. Its rendering options include path tracing, light tracing, stochastic progressive photon mapping, progressive and interactive rendering, and spectral rendering. For shading, appleseed supports Open Shading Language with shaders compiled as needed. Production tools include motion blur, AOVs, Cryptomatte, adaptive sampling, denoising, and render checkpoints that can be resumed. The software integrates natively with Autodesk Maya, Autodesk 3ds Max, Blender, and Gaffer. It handles OBJ geometry and image formats including OpenEXR, TIFF, HDR, PNG, JPEG, and PSD. Developers can use its C++ and Python APIs or extend it with external C++ plugins. appleseed runs on Windows, Linux, and macOS, and its feature list also includes an API platform. The project is developed by an international volunteer team from animation and visual effects. Its listed release is version 2.1.0-beta, dated September 21, 2019. For questions, the project points users to its Discord server or forum; private email may take longer to receive a response.
