DreamWorks Updates MoonRay to Version 2.40 with New Tools 🚀

Published on February 19, 2026 | Translated from Spanish

DreamWorks has released version 2.40 of its MoonRay rendering engine, an open-source project. This update introduces a new graphical interface and a light path viewer, a tool that allows analyzing the behavior of lighting. Development continues to optimize performance and production utilities for animation and VFX workflows.

Advances in Ray Tracing and Lighting Analysis 💡

The addition of the light path viewer facilitates the debugging and adjustment process of lighting, allowing artists to see how rays interact with materials. MoonRay 2.40 maintains its ray tracing-based architecture, compatible with distributed rendering to handle complex scenes. The improvements in the graphical interface aim to integrate seamlessly into modern production pipelines, offering more direct control over render parameters.

Finally, we can see where those annoying glares come from 👁️

With this new path viewer, maybe now we'll discover the exact origin of that reflection that strangely lights up a character's ear from a point that shouldn't exist. It's like giving the engine glasses to explain its lighting whims. A useful tool for when the scene seems lit by a ghost with a flashlight.
