Hey Calamitykebab
Try Version 1 of the shader as it had several parameters used to get this effect.
In short: use simple textures with sparse detail, a flattened base colour setting in the shader and 1 pixel outline and detail lines.
To get the sparse detail you add subtle hard-edged patches of colour variations to your textures, which the line detail shader will then outline.
Finally there’s some shadow settings for hardening up the darker areas.
