Warning on Post Process Material - For Platform DirectX Mobile at quality level High

Hello, I’m encountering this compilation error while working on a post-process material. I suspect it originates from a Scene Texture node set to World Normal. Despite this warning, the post-process seems to work after the popup. Could this message indicate that it won’t function on certain systems? Can it be ignored?

When I added quality switch to my material also had that pop up, useless generic message that tells me absolutely nothing. No idea what that is about.

Oh and it gets better, now even after deleting that node I get quality compiling error popups over and over, seems like unreal permanently tainted my master shader. To say I am ■■■■■■ is understatement.

I’m getting this now when I try and save a material, literally no other warning or indicator as to when to do to fix it

Most of the time this happens when you haven’t assigned a node in something like quality switch or are trying to do math between incompatible types, like float 3 to float 4. Can you share your shader graph and I’ll troubleshoot?

Nah, when you switch to mobile preview in viewport it also changes Platform Stats settings in Material Editor.

So go to material editor and at the bottom there is Platform Stats tab. If its not there then at the tom Window > Platform Stats and now at the bottom go to the Platform Stats tab and in the right bottom corner there will be settings. Uncheck mobile and that window stops popping up because material editor no longer checks for mobile compatibility.
