How can I make powerlines?

I am trying to model a transmission tower and I want to make these powerlines using a transparent texture. Am I going to need a bunch of line segments in the plane for the texture to work because the image is stretching?

I want this model to be used in a game engine so I don't want much polygons on the powerlines.

I usually texture in substance and clip studio and was going to make the powerlines just a black line across the UVs.

    I would suggest NOT using an alpha blended surface for these. The texture is going to be filtered with distance, and the lower MIPS will be very blurry.

    It's generally better to just use pure opaque geometry. Include enough cross-sections to reduce long thin triangles, which can cause performance issues with some GPUs. Besides, the extra edges will give a smoother curvature to the hanging wires.

    What engine and what hardware are you targeting with these assets? Mobile for example is going to have very different needs than console than PC.

    geometry is cheap - start with that and only start thinking about doing something clever if you really need to.
