What it is

Thea Render is a 3D renderer that combines unbiased and GPU rendering engines within one framework. Its light simulation and spectral rendering calculate global illumination, reflections, refractions and caustics across the visible wavelength spectrum. Presto and Nitro provide GPU-accelerated rendering, while NVIDIA and Intel AI denoisers are available for interactive and production work. The SketchUp integration supports interactive rendering in the SketchUp view or a separate Thea window. The Rhino integration supports Grasshopper geometry during interactive rendering and Rhino fly-through and turntable animations. An integrated content browser provides materials, models and environments, including community-submitted materials in an online repository. Thea Node lets machines on a local network contribute to rendering, even when a node uses a different operating system from the integration. SketchUp support covers versions 2018–2026; Rhino compatibility includes Rhino 6.33, 7.17 and later, and Rhino 8. Thea Node is free. The listed SketchUp and Rhino integrations each cost $675 a year, billed 3-Years, and do not include a standalone application.
