The problem is that I have to loop through all of the sample points, and I keep getting the error “forced to unroll loop, but unrolling failed.” I've tried various different things to try and fix such as using the [loop] attribute, in which case I get “can't unroll loops marked with loop attribute”, and I've tried using the [unroll()] attribute to specify the amount of iterations the loop goes through, but I get the unrolling failed message again. I was wondering if anyone could suggest a solution? Here is my code:

#pragma kernel CSMain

struct BlendInputData
{
    int x;
    int z;
    int i;
    int blendRadius;
    int biomeIndexIterat;
    int xSize;
    int zSize;
};

StructuredBuffer<BlendInputData> inputData;

static int blendRadius = inputData[0].blendRadius;
static int biomeIndexIterat = inputData[0].biomeIndexIterat;
static int xSize = inputData[0].xSize;

int MeshIndexToBiomeIndex(int meshIndex)
{
    int biomeIndex = meshIndex;
    biomeIndex += (2 * blendRadius * blendRadius) + (blendRadius * xSize);
    biomeIndex += floor((meshIndex / (xSize + 1)) + 1) * 2 * blendRadius;
    return biomeIndex;
};

float Vector2Distance(int xOne, int yOne, int xTwo, int yTwo)
{
    float distance = sqrt(pow(xOne - xTwo, 2) + pow(yOne - yTwo, 2));
    return distance;
};
