i am making a post procesing shader but get error [SM5] /Engine/Generated/Material.ush(2111,7-10): error X3000: syntax error: unexpected token ‘mean’

can anybody help

float3 mean[4] = {
  {0, 0, 0},
  {0, 0, 0},
  {0, 0, 0},
  {0, 0, 0}
};

float3 sigma[4] = {
  {0, 0, 0},
  {0, 0, 0},
  {0, 0, 0},
  {0, 0, 0}
};

float2 offsets[4] = {{-RADIUS, -RADIUS}, {-RADIUS,0}, {0,-RADIUS}, {0,0}};

float2 pos;
float3 col;

for(int i = 0; i < 4; i++)
{
  for(int j = 0; j <= RADIUS; j++)
  {
    for(int k = 0; k <= RADIUS; k++)
    {
      pos = float2(j, k) + offsets[1];
      float2 uvpos = UV + pos/VIEWSIZE;
      col = SceneTextureLookup(uvpos, 14, false)

      mean[i] += col;
      sigma[i] += col * col;
    }
  }
}

float n = pow(RADIUS + 1, 2);

return mean[0] / n;

Hi @Larslloyd

Is it possible (i maybe wrong) that float3 doesnt exist and it should be TVector<float,3> ?

Inalso believe that arrays use the TArray container rather than explicitly declaring them, but again i may be wrong

But if im right it could be the reason you Mean variable does not initilaise and throws that error

the error is gone but now it says [SM5] /Engine/Generated/Material.ush(2082,1-7): error X3004: undeclared identifier ‘TVector’ have tryed to fix it but it dident do you know this one 2

Sorry change it to FVector

It looks like you are just missing a semicolon on this line in your loop (causing the compiler to be confused about the subsequent line):

col = SceneTextureLookup(uvpos, 14, false);

Use of float3 etc should be fine.
