I have an adjustable Resolution Scale setting in my game that affects textures including the red dot scopes attached to the weapons. However, I want to exclude the textures/materials of these red dots so they remain high res. I tried many things including setting the mip gen setting to nomipmaps, putting it in UI texturegroup, setting downscale to 1 (do not scale texture) etc. but it keeps downgrading these textures.
Epic setting 100% resolution scale
Low setting 50% resolution scale
So basically I want keep the red dot texture at 100% resolution scale but still keep the benefits of resolution scaling on everything else. Is this possible and if yes, how do I do this?
