People may also try this custom node for a soft guassian like appearance. lower-cased uv and no extra parameter to adjust weight.
float3 res = 0;
float2 invSize = GetPostProcessInputSize(0).zw;
int TexIndex = 14;
float weights] =
{
0.01, 0.02, 0.04, 0.02, 0.01,
0.02, 0.04, 0.08, 0.04, 0.02,
0.04, 0.08, 0.16, 0.08, 0.04,
0.02, 0.04, 0.08, 0.04, 0.02,
0.01, 0.02, 0.04, 0.02, 0.01
};
float offsets] = { -2, -1, 0, 1, 2 };
uv *= 0.5;
for (int i = 0; i < 5; ++i)
{
float v = uv.y + offsets* * invSize.y;
int temp = i * 5;
for (int j = 0; j < 5; ++j)
{
float u = uv.x + offsets[j] * invSize.x;
float2 uvShifted = uv + float2(u, v);
float weight = weights[temp + j];
float3 tex = SceneTextureLookup(uvShifted, TexIndex, false);
res += tex * weight;
}
}
return float4(res, 1);
Hi Kory, the effect does not seem to be resolution independent. It seems to be always a fixed pixel size. I tried to multiply this out by again multiplying/dividing by invSize.x/y, but it still is resolution dependent.
