It’s babylon. With GLBs it’s good both in preview and stable. It’s only .babylon in preview version that is bad. And by the way it happened from what I remember just a day or two ago. It was okay earlier.
There are just several cubes there and they also show up in my code stretched. But in playgroung they show up okay. The question is what engine version is used in the playground? Is it the preview version? The problem on my side is only visible in the preview version. On stable it’s okay.
One more weird thing I’ve noticed is that when I load the engine from https://cdn.babylonjs.com/babylon.js, it shows me 4.1.0 without rc.9 in the console, and also shows me a stretched picture BUT not on all scenes from Unity. There is a scene which is not affected by this!
