For shading, it supports Open Shading Language and on-the-fly shader compilation. Production tools include motion blur, AOVs, Cryptomatte, adaptive sampling, denoising, and resumable render checkpoints. Native integrations are listed for Autodesk Maya, Autodesk 3ds Max, Blender, and Gaffer. It works with OBJ geometry and image formats including OpenEXR, TIFF, HDR, PNG, JPEG, and PSD. Developers can use C++ and Python APIs or extend the engine with external C++ plugins. The listed plan costs nothing and is under the MIT license.
