Devlog/Tutorial 05 - Unreal Engine Grand Strategy, Blood and Iron, Africa, RGOs, HQX Guide

This update took quite a while to do cause there's also a lot of hidden pop features implemented, like research point and bureaucracy production from percentages of pops which aren't fully done yet. If you're a solo or team of devs working in unreal on a Grand Strategy project, feel free to email me for help (:

Put this in a CUSTOM node;

struct Functions
{
 float4 HQX_AA(float2 UV, float Contrast, Texture2D Tex, sampler TexSampler, float2 P1, float2 P2, float3 Sum)
 {
float2 PixleUVs = float2((UV.x)*8192, (1-UV.y)*4096);
float PixleTri=dot(PixleUVs-floor(PixleUVs+P1)-0.5, normalize(float2((P2-P1).y, -(P2-P1).x)));
float Alpha = saturate(round((Contrast-PixleTri)*10));
PixleUVs = 1/float2(8192,4096) * float2(1,-1);

float3 TexP1 = Texture2DSample(Tex, TexSampler, UV + PixleUVs*P1);
float3 TexP2 = Texture2DSample(Tex, TexSampler, UV + PixleUVs*P2);
float Condition = length(TexP1-TexP2);
if (Condition != 0) return float4(Sum, 0);
return float4(lerp(Sum, TexP1, Alpha), 1);  
}
};

if(Cull == 0) return Sum.xyz;
