Cross hatched Postprocess mat

Hi Unreal Dev Community, that my firsy post here, so please do not be angry. Im trying create a cross hatched material for post process (like that

, i use Gbuffer-D for my texture but it store a CustomData.XYZW and if in defaultlit-shading model i can use it as i want, in other shading models i can’t, because they store Subsurface data as RGB and A as an opacity. and now i don’t know how to achieve that effect that can give me post process material in other way. could u guys give me an idea maybe i can do this without Postprocess mat? and if i want to make custom Shading model i still cant use CustomData, so how i can avoid that problem?
