Environment has too strong reflection on objects

[brightMoon]

After several months, I discovered the reason for the strong reflection of glass: the useRadianceOverAlpha attribute.
For the glass of my car, setting useRadianceOverAlpha to false would appear more normal Of course, other engines such as Threejs and PlanCanvas will not display such strong glass reflections BJS provides more options for adaptation, but familiarity with BJS’s PBRMaterial documentation is necessary to solve the problem.

Visible reflections despite opacity information in base texture in PBR material

It depends most surfaces you can see through will retain reflection which is why it is our default mode. You can prevent them by setting useRadianceOverAlpha and useSpecularOverAlpha to false

Another question is why BJS defaults the useRadianceOverAlpha of PBRMaterial to true?
