Device Profile seems to have no effect?

I noticed the render quality on my iphone is rather poor, so I wanted to change the render settings.
So I read about device profile, copied the basedeviceprofiles.ini to my projects config folder, and added lines in the iphone 4s section.
This didn’t seem to have any effects, but then I learned there is also a window for device profiles in the editor. So first question: what do I use? the ini or the window?
I noticed that the lines I added in the ini didn’t show up in the editor window for device profiles.
So I added those lines there too:

  • BloomQuality 5
  • MobileContentScaleFactor 2
  • MobileMSAA 4
  • MobileHDR 1

But it didn’t seem to have any effect either. It still looks low resolution, with no anti-alias, and no bloom effects.

So what am I doing wrong? Am I forgetting something? Are there things I can check to see what goes wrong?
Thanks for any information!

Usually if you do them in console its only a temporary setting. If you place it in the .ini it becomes the “Default” setting (unless you change it in the console)

Since most of the things you are adjust are rendering, they should start with “r.” at the beginning , So r.MobileHDR 1 . r.ShadowQuality 0, etc… (A bunch can be found Scalability Reference for Unreal Engine | Unreal Engine 5.3 Documentation ). You can place them in BaseEngine.ini

Example: You’ll see

[/Script/Engine.RendererSettings]

r.MobileHDR=True

I have not tried this on iOS specifically but this is how the engine handles it

Asfar as updating/tweaking Device Profiles, make sure your it looks something like this

[iPhone4S DeviceProfile]

DeviceType=IOS BaseProfileName=IOS

MeshLODSettings=

TextureLODSettings=

+CVars=r.MobileContentScaleFactor=2

+CVars=r.BloomQuality=1

+CVars=r.DepthOfFieldQuality=1

It must have +CVars=r.*************
More info can be found Setting Up Device Profiles in Unreal Engine | Unreal Engine 5.3 Documentation

Yes I did do the +CVars=r. in the .ini file, sorry I wasn’t clear about that.

What I meant with the editor dialog, I did not mean using the console. There is a specific window in the editor (Window->Developer Tools-> Device Profiles) where you can add all this lines to device profiles, using a nice dialog where you can choose the config strings from a dropdown menu.

But I get not effect from either…

I forget a lot, but you have to recook the assets to get the ini changes.
