Babylon.js 9.25.0 Released

Babylon.js 9.25.0 is a feature-heavy point release aimed squarely at XR and rendering workflows. The biggest additions are on the WebXR side: dynamic viewport scaling, tracked sources support, composition layer controls and limits, depth-sensing lifecycle controls, advanced controller haptics, and a hardening pass for experimental WebGPU XR support. For teams shipping immersive experiences, that means more control over performance, input, and device capabilities without having to build as much glue code themselves.

Rendering and material workflows also get a practical upgrade with white balance controls in image processing, exposing Kelvin temperature and tint adjustments. That change lands across Core, Inspector, and Materials, so it should be immediately visible in both runtime pipelines and authoring tools. In practice, this gives developers a cleaner way to tune scene color response and camera-like grading without bolting on custom post-processing.

The release also fixes a few issues that could cause real-world headaches: IBL shadows no longer fail silently on Adreno mobile GPUs, WGSL output is corrected for PowBlock and TriPlanarBlock, OpenPBR backend behavior is brought back into consistency, and late notifications for Observable are fixed. Loader preprocessing now handles parent-relative glTF resources more reliably, and the Sandbox camera query controls have been cleaned up.

For developers, this is the kind of update that matters most if you’re already leaning on Babylon’s XR stack, WebGPU path, or mobile rendering. There’s no obvious breaking change called out...
