Unable to set r.Shadow.TexelsPerPixel in Scalability ini

After migrating to UE 4.12 I’m no longer able to set r.Shadow.TexelsPerPixel in the project DefaultScalability.ini file, it always loads with the default value from the constructor.

The console variable has been declared as ECVF_RenderThreadSafe but not ECVF_Scalability, this prevents to set the value from config (and even prevents packaging if I try to do so), is there a reason for not allowing this value to be set in the scalability settings anymore?

I need to change it in order to get good quality shadows in a game where all gameplay objects are relatively small in the screen. I also would like to keep using the vanilla engine without having to recompile it just to change this value.

Thanks for your help or info!

Was there ever a resolution to this? I’ve run into the same issue in 5.3 and don’t believe editing the source default, or throwing out the whole concept of the scalability.ini in favor of setting values via blueprint is a reasonable solution.
