Back in 2022 DreamWorks Animation announced they were open-sourcing their MoonRay renderer and was then published in early 2023 for this renderer that has been used in a variety of featured animated films. Since then they have continued advancing this MoonRay code via the open-source OpenMoonRay project and this week published their newest feature update.

OpenMoonRay 2.40.0.1 was published this week and most notably introduces an experimental new GUI alternative to its existing one. The new GUI is relying on the ImGui library and is focused on a better user experience with usability enhancements like pixel inspection, snapshots, a status bar, and improved path visualizer drawing. OpenMoonRay's existing GUI was using the Qt toolkit but they have found better success now with ImGui.
