- Description:
- TrueTrace is a high-performance global illumination pathtracing renderer built in Unity, designed for others to use. It uses pathtracing to create realistic images and is customizable and easy to use. While it's not intended for real-time use, it's perfect for renders. The package is still a work in progress, and feedback is highly encouraged. It supports various features, including Disney BSDF for materials, complex emissive meshes, runtime transform and removal of objects, and more. It also supports various Unity features, such as PBR texture support, Next Event Estimation, and Object Instancing. The package is available for free, but contributions are welcome through Patreon. A demo is available for download, and the package is compatible with Unity's Built-in, HDRP, and URP.
