I used Unity 5.6.5p2 with Low Poly: Free Pack to test WebGL WASM rendering on iOS 11.3 beta3 Safari, I got following phenomena:
In ASM.js mode, it works well as attached pic1;
But, in WASM mode, the scene crashes totally as pic2.
It is weird, what has happened? Any information about it is pretty helpful!
