Question Removed smooth attenuation but there is still fall-off?

So basically I went into the Universal RP/ShaderLibrary/Lighting.hlsl file and changed the GetAdditionalPerObjectLight function to this

Code (CSharp):

1. // Fills a light struct given a perObjectLightIndex
2. Light GetAdditionalPerObjectLight(int perObjectLightIndex, float3 positionWS)
3. {
4.     // Abstraction over Light input constants
5. #if USE_STRUCTURED_BUFFER_FOR_LIGHT_DATA
6.     float4 lightPositionWS = _AdditionalLightsBuffer[perObjectLightIndex].position;
7.     half3 color = _AdditionalLightsBuffer[perObjectLightIndex].color.rgb;
8.     half4 distanceAndSpotAttenuation = _AdditionalLightsBuffer[perObjectLightIndex].attenuation;
9.     half4 spotDirection = _AdditionalLightsBuffer[perObjectLightIndex].spotDirection;
10. #else
11.     float4 lightPositionWS = _AdditionalLightsPosition[perObjectLightIndex];
12.     half3 color = _AdditionalLightsColor[perObjectLightIndex].rgb;
13.     half4 distanceAndSpotAttenuation = _AdditionalLightsAttenuation[perObjectLightIndex];
14.     half4 spotDirection = _AdditionalLightsSpotDir[perObjectLightIndex];
15. #endif
16.  
17.     // Directional lights store direction in lightPosition.xyz and have .w set to 0.0.
18.     // This way the following code will work for both directional and punctual lights.
19.     float3 lightVector = lightPositionWS.xyz - positionWS * lightPositionWS.w;
20.     float distanceSqr = max(dot(lightVector, lightVector), HALF_MIN);
21.  
22.     half3 lightDirection = half3(lightVector * rsqrt(distanceSqr));
23.     float range = rsqrt(distanceAndSpotAttenuation.x);
24.     int distance = (distanceSqr / range);
25.     half attenuation = clamp(1.0f - distance, 0.0, 1.0);
26.  
27.     Light light;
28.     light.direction = lightDirection;
29.     light.distanceAttenuation = attenuation;
30.     light.shadowAttenuation = 1.0; // This value can later be overridden in GetAdditionalLight(uint i, float3 positionWS, half4 shadowMask)
31.     light.color = color;
32.  
33.     return light;
34. }

Since the distance is an integer the attenuation will immediately change from 1 to 0 so there should be no smooth fall-off. At first it looked like it worked but upon closer inspection there is still more light at the center than the edges



I have turned off specular highlights and environment reflections on the table material but the highlight is still there
