How to use Sprite Atlas with Assetbundles in WebGL?

Hello Guys, does someone knows why when I use this Sprite Atlas…

alt text

In my WebGL build and I include it in an assetbundle the sprites don’t show up…
Is there, somewhere in the internet, a proper documentation on how to use sprite atlases with WebGL + Asset Bundles? I can’t make it work… Thanks!

Nobody…? the sprite atlas is an obscure mystery in Unity :stuck_out_tongue:
