LineRenderer not affected by material alpha setting

Why does the LineRenderer not appear to respect the material alpha value set in SetColors? I'm setting it to values from 0.9 to 0.0, but the opaqueness never seems to vary. Why is this?

Check your shader. The following worked for me:

Shader "line" { Properties { _Color ("Color Tint", Color) = (1,1,1,1) _MainTex ("SelfIllum Color (RGB) Alpha (A)", 2D) = "white" } Category { Lighting On ZWrite Off Cull Back Blend SrcAlpha OneMinusSrcAlpha Tags {Queue=Transparent} SubShader { Material { Emission [_Color] } Pass { SetTexture [_MainTex] { Combine Texture * Primary, Texture * Primary } } } } }
