Wireframe Shader

An article by mgear

unity-wireframe-shader

Founded some mesh wireframe shader in the unity 5.5f2 builtin shader folder (builtin_shaders-5.5.0f2\DefaultResourcesExtra\VR\Shaders)..
Changes:
– Added fillcolor, outline color
– Added [x] Discard option (draws only lines)
– Removed stereo rendering keywords
– Removed color by distance thing

Download shader:
https://github.com/UnityCommunity/UnityLibrary/blob/master/Assets/Shaders/2D/Effects/WireFrame.shader

Tip: You can assign this material shader as a 2nd material to your mesh, to draw original material + wireframe (with [x] discard enabled)

  could set black color to alpha 0 and add blending mode https://docs.unity3d.com/Manual/SL-Blend.html like Blend SrcAlpha OneMinusSrcAlpha // Traditional transparency

Would this work on mobile builds(Android/IOS) ?

  Not tested, but i think should work. (i’ve read that shader with Discard might have issues/slowdown in some phones..)

    Apparently it doesn’t work for android as it states that the gpu is not compatible. And, I was so hopeful too!!!
