Black Shape on White Background Artefacts

Hi All

I am trying to show the user a black shape on a white plane. This looks correct in the material editor when I display it there:

But in-game it appears to be a much lower resolution or there can sometimes be other artefacts around the edges:

I did think that it was due to me making the texture have emissive colour (I want to it be visible no matter the light condition) however it still exhibits this behaviour without using the emissive colour attribute.

Any help is appreciated

Hi Fenther, what does your material network look like?
You mention emissive use because you want it to ignore lighting, but what about the Unlit shading model in the material?
I’m not certain why it looks odd only in game, could you also post your texture settings?
