Hey Everyone!
@PatrickRyan is up with the video this time…and WOW does he deliver a great one! If you’ve ever wanted to know how to take a panoramic image and use it to light your Babylon.js scenes, then this is the video for you!!!
Follow along with this playground:
Test spheres glb:
Adobe HDRI:
HDRI Haven:
High Contrast HDRI in Image Based Lighting:
Sandbox:
Will this feature be available in BabylonJS code or will it stay only in the sandbox?
Otherwise I guess I can find the code here but I don’t know where to search: Babylon.js/sandbox at master · BabylonJS/Babylon.js · GitHub
Because that would be huge to also be able to make this conversion directly in our app!
Again thanks for making our life easier with this kind of improvements 
You can use HDRCubeTexture to load an HDR file and pre-filter it, then use EnvironmentTextureTools.CreateEnvTextureAsync to convert to a .env file.
See this thread and PG.
