How to set the light scattering effect in Composer?

[Simplychenable]

to clarify, the renderer i was referring to was the option for viewport display. RTX-Realtime, RTX-Interactive (path tracing), Iray, etc. the reason being some renderers are more accurate than others in representing realistic behaviors.

here is a thread that may have some pointers for you:

How to make light passing through the Glassic object and illuminate the object behine the Glassic object

When I combine the thick_glass_v2 and OmniSurfaceBase materials using OmnisurfaceblenderBase and output them on mdl:surfaces, why can adjusting the base of OmniSurfaceBase, when its weight is higher, control the translucency of the object? It seems that light can penetrate the object and illuminate the cube behind it. But when I increase the weight of thick_glass_v2, although the object gains a glass texture, it can no longer transmit light, and the object behind the glass cannot be illuminated.…

and from the doc with some addition insights thatcmay be relevant:
