Code -

float2 uv = UV;

float3 resultColor = float3(0, 0, 0);

float paddingX = PaddingX;

float paddingY = PaddingY;

uv.x = (uv.x - paddingX) / (1.0 - 2.0 * paddingX);

uv.y = (uv.y - paddingY) / (1.0 - 2.0 * paddingY);

float2 center = float2(0.5, 0.5);

float radius = Radius ;

float distanceToCenter = length(uv - center);

if (distanceToCenter <= radius)

resultColor = float3(1, 1, 1);

return resultColor;
