Volumetric Fog same scalability, different results. (comparing 5.03/5.1)

Hi guys,

I just test my project on UE5.03 and converted to UE5.1 then in 5.1 I have some issues with volumetric fog.

Volumetric fog works properly in “Epic” Scalability setting in 5.03, while I can get the same volumetric fog effect in 5.1 only in cinematic scalability setting. (“Epic” scalability in 5.1 shows the wrong Volumetric fog result compared to project in 5.03)

Here is SS:

Have any changes been made in volumetric fog formation? Because the “cinematic” scalability result in 5.1 gives the same result as the “epic” scalability in 5.03. really challenging in terms of performance.

It’s probably this bug, which is fixed in the coming 5.1.1 hotfix.

Though I’m not 100% sure, because that bug is still present on cinematic scalability for me.

Unreal stores its scalability presets in the BaseScalability.ini file in the /Engine/Config directory, (or there may be one in your project directory if you are not using the defaults.) I’d suggest you compare your 5.0 ini to your 5.1 and look for differences.
