Just noticed that the provided playground works in Chrome, but not in Safari. The playground is a white screen in Safari stuck on **Loading assets… Please wait.** and **createScene function must return a scene.**

Edit: Just realized my Safari’s on WebGL1, which is probably causing the issue. Works fine in other browsers on WebGL2.

It is because both cascaded and PCF shadows are not supported by webgl1 so you should not create them in webgl1 device like ios.
