Would there be a performant way of adding an outline?

Checking all neighboring pixels with IsPixelInLine_float seem to be a lot of work.

Sampling tPackedPoints in S_BresenhamMultiLine.hlsl to get packedPoints/packedPoints2 returns the wrong packed point in a variety of configurations, which causes some lines to not get rendered entirely.

I managed to fix it by replacing the first part of the outer for loop of IsPixelInLine_float with

int xCoord = floor(t/2.0f);
float4 packedPoints = tPackedPoints.Load(int3(xCoord, 0, 0));
float4 packedPoints2 = tPackedPoints.Load(int3(xCoord+1, 0, 0));

unity 2022.3.11 urp2d
Shader error in 'Game/S_BresenhamMultiLineRenderer2D': 'CombinedShapeLightShared': cannot implicitly convert from 'float4' to 'struct SurfaceData2D' at line 148 (on d3d11)

I downloaded the repo and copied the Assets/LineRenderer2D folder to my project. I fixed the shader errors using this commit.
I put MultiLineRenderer2D prefab to the scene and adjusted the points. It is visible in the editor window but when I build the game, it becomes invisible. Is there a way to fix it?

Hello, sorry I am terrible with shaders, but I am getting this error with several files, specifically these:
Couldn't open include file 'Assets/LineRenderer2D/Shaders/S_BresenhamLine.hlsl'.
Couldn't open include file 'Assets/LineRenderer2D/Shaders/S_BresenhamMultiLine.hlsl'.

Any advice on what i need to change/update to get these fixed?

Currently using 2023.2.

The provided components work fine when not part of any canvas, but when put on a canvas, the gizmos will show the correct end points but the line is not drawn.

It is worth noting, what considered "center" of the object (the transform handle) is not even on the magenta gizmos line.

I ain't prodigy in shaders but... could there be a way to make this work on canvases?

To make this work in Unity 2021.3 I had to replace all instances of

if (_IsUnlit == 0.0f)
{
    // Lighting
    finalColor = CombinedShapeLightShared(finalColor, maskColor, i.screenPos);
}

with:

if (_IsUnlit == 0.0f)
{
    // Lighting
    SurfaceData2D surfaceData;
    InputData2D inputData;
    surfaceData.albedo = finalColor.rgb;
    surfaceData.alpha = 1;
    surfaceData.mask = maskColor;
    inputData.uv = i.screenPos;
    finalColor = half4(CombinedShapeLightShared(surfaceData, inputData).rgb, finalColor.a);
}
