It seems that we can’t have two Cascaded Shadow in the same scene when using a MAC computer. In this playground, we can’t see the ground and it creates a WebGL error in the console: https://playground.babylonjs.com/#IIZ9UU#104
I am using a MacOS Big Sur with Chrome Version 89.0.4389.114
We do not have this issue with a Windows computer.
Have a good day everyone
