Updated glTF Support — KHR_materials_diffuse_transmission
Babylon.js 8.0 continues the long rich tradition of supporting every extension update to the glTF format. As glTF advances, Babylon.js is in lock-step with support for those advancements. Babylon.js 8.0 brings support for the very beautiful KHR_materials_diffuse_transmission!

More glTF Loader Options
Babylon.js 8.0 unlocks new loader options for glTF objects allowing you to programmatically load your assets with pre-determined specifications, such as loading at a specific LOD (Level of Detail). These new loader options will provide new flexibility and control of how you bring assets into your Babylon.js scenes!

GPU Mesh Picking
Picking meshes in a scene can be an expensive feature since the CPU has to loop through every piece of geometry to find the triangle that most closely intersects the ray cast from the picking location.
Ready for some wizardry? Babylon.js 8.0 introduces the ability to pick meshes from directly from the GPU! Yup, that’s right. This means that in complex scenes, where picking is required, you can boost performance by offloading this to the GPU.

GPU Bounding Box
Bounding Box calculation can be expensive, especially if you have a few animated meshes with a large number of vertices. Babylon.js 8.0 introduces the ability to pass Bounding Box calculation to the GPU, freeing up valuable cycles on the CPU and improving performance for your scene.

EXR Texture Support
Babylon.js 8.0 also brings support for EXR files. This feature-rich image format unlocks some new superpowers for you to use in Babylon.js. Negative pixel values, for example, can be used to store complex visualizations as a texture format that can now be read in Babylon.js!

WebXR Depth Sensing
Babylon.js 8.0 brings support for a new and exciting WebXR feature called “Depth Sensing.” This feature uses depth information captured from devices to give developers the ability to overlay real world visuals “on top” of computer-generated images! You just have to see it to believe it. It feels like magic!

A Peek Ahead
Phew! Babylon.js 8.0 is by far the platform’s biggest release to date. There’s so much goodness packed into it that it feels like you’ve been scrolling forever! Would you believe there’s even more in active development?!!! Here’s a tiny tease about a couple of things on the horizon:
glTF Interactivity Support — If you follow the advancement of the glTF file format, then you know that exciting things are coming with the interactivity workstream. We’re actively working on supporting this incredible new extension that will allow asset behaviors to travel with your assets. That means that interactivity is no longer tied to one specific creation tool or engine!
OpenPBR Support — OpenPBR is an open standard for how Physically Based Rendered materials look when rendered. Guess what’s in active development in Babylon? 
Tooling For Everyone — We understand that everyone who comes to the Babylon platform comes from different backgrounds and experience levels, from software engineers at the top of their game, to students and artists just beginning their computer graphics journey. We are passionate about ensuring that everyone who is interested in leveraging Babylon.js has the tools and workflows to do so. We’ll have more to share on this later this year.
Thank You
With each evolution of Babylon.js comes a revolution in web rendering technology and an overwhelming feeling of gratitude. The Babylon platform simply wouldn’t be possible without the incredible community of developers, the 500+ contributors, and the steadfast advocates that contribute their knowledge, expertise, help and passion to this amazing technology. “Thank you” to each one of you for all that you do to help make Babylon.js one of the most powerful, beautiful, simple and open web rendering platforms in the world.
