UE4 unchangable Normal Map compression settings (unavoidable compression artefacts)

[Thibaud.be]

Hello,

Would it be possible to have some feedback regarding this still standing issue:

thanks a lot.

@Thibaud.be , did you try this in the latest 4.27 version?

We migrated the project to use the latest unreal engine 4.72 version.
Unfortunately the issue remains:

• Substance rendering engine in ue4 runtime will stubbornly revert the normal to BC5 Format.
• Changing the "Lossy compression amount" or "Compresion quality" has no effect on the rendered normal output.

This happens when calling substance sync or async rendering methods at runtime.

Is there any chance for this issue to ever get fixed ?

Hi,

Thanks for checking in. It will take some time to provide a fix for this issue in UE 4.27. 

Are there any plans to migrate your project to UE 5?
