On my PC uncheck “groundReflection” the reflections gone,but when i tested on my friends’s PC,it looks the same with yours.But with “groundReflection” checked,it looks all the same on me and my friends’s PC.
Three.js created a hidden ReflectorForSSRPass plangeometry to work with SSRPass.
And developed a new shader for it, and this does solve the problem:

I’m new to 3D develope, and new to BJS and TJS too, so i can’t help BJS solve this problem for now, but i while learn and try from now on.
For now, i need developers in the forum help me to this.
