What Thea Render is

Thea Render is a 3D renderer that brings unbiased and GPU rendering engines into one framework. Its light simulation and spectral rendering calculate global illumination, reflections, refractions and caustics within the visible wavelength spectrum. The software includes Presto and Nitro GPU-accelerated engines, along with NVIDIA and Intel AI denoisers for interactive and production rendering. Thea for SketchUp 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 Thea 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. The SketchUp integration supports versions 2018–2026; Rhino compatibility includes Rhino 6.33, 7.17 and later, plus Rhino 8. The listed SketchUp and Rhino licenses each cost $675 a year, billed 3-Years, and do not include a standalone application. Thea Node is free.
