    Hello,
    im trying to create a Laser-Shader and put it on a Line-Renderer. Everthing works fine except when i change the width of the Line-Renderer: the texture position on the mesh of the Line-Renderer will be broken. (maybe, if the width is zero the first line segment is a triangle?!) I want the texture to align from the starting point to the end point. Also the texture is distoreded when using End Cap Vertices.

    Width: Start and End 1.0

    Width: Start 0.0 and End 1.0

    What am i missing? Is it possible to align the texture like this:

    I'am using HDRP and Shader Graph:

    These are limitations of the built in LineRenderer.

    You could evaluate some asset store offerings as alternatives though they may cost money. Eg Vectrosity.

    We are currently prioritising other areas of Unity, so I’m not sure if improvements here are likely.

    Thanks for your reply! Now I can sleep well, because its a technical limitation and not my inability! :)

    I will check the store!

    Thank you!
