• Intel’s Discontinued Open-Source OpenPGL Project Finds A New Home Back in 2022 Intel announced OpenPGL as an open-source library for path guiding to help enhance the quality of path-based renderers. • With time Blender began making use of OpenPGL and other industry interest and adoption. • Unfortunately, Intel quietly ended work on OpenPGL in 2025 but has now fortunately found a new home. • The Apache 2.0 licensed Intel Open Path Guiding Library was started as part of the Intel (oneAPI) Rendering Toolkit and found use by not only Blender but also the likes of V-RAY, Houdini Karma, Illumination, and Disney Hyperion. • But amid cost-cutting at Intel over the course of 2025, OpenPGL development ceased as one of many open-source projects Intel cut back on. • Intel’s OpenPGL repository on GitHub hasn’t been archived or formally discontinued but hasn’t seen any commits now in eight months.
Article Summaries:
- Intel’s open‑source OpenPGL, a path‑guiding library first released in 2022 as part of the Intel oneAPI Rendering Toolkit, was quietly halted in 2025 amid cost‑cutting. The project, licensed under Apache 2.0, had gained traction in the VFX community, powering Blender, V‑Ray, Houdini Karma, Illumination, and Disney’s Hyperion (used in Zootopia 2). Although the GitHub repo remains unarchived, it has seen no commits for eight months. The Intel Technical Advisory Council confirmed the shutdown, and the Academy Software Foundation (ASWF) has now taken over the project, forming a new working group to continue development.
