How To Fix Unity3d Transparent Shader Not Respecting Z-Index

Before and After: Unity3d Transparent Shaders Respecting Z-Index

Before and after. Bright colours used to demonstrate effect of fix.

The fact that, by default, the transparent shaders in Unity3d do not work well behind or in front of objects has been a problem for years. Here’s an easy fix that might solve it for you.

Steps

  1. Make a duplicate of the transparent shader in question. For me, this was Unlit – Transparent Tint. I found it by searching my Project window in the Unity3d editor for “Unlit”.
  2. Edit the new shader in a text editor (default: MonoDevelop).
  3. On line 1, change the name of your shader to something you’ll remember. This is where it will be in your shader selection dropdown in the editor.
  4. Under the SubShader section, add +1 to the item in the “Queue” section. For me, this became “Queue” = “Transparent+1”.
  5. Save your shader.
  6. Apply it to your game object.

That’s it! With any luck, the object with your transparent shader should now appear in front of other game objects which also use a transparent shader.

Using Unity3d 4.x In a Team

I’m working in a team for the 2015 NASA Space Apps Challenge and this year, like last year, we’ve run into a billion and a half problems working with Unity3d and git with more than one person. After some searching I found an awesome website that included a gitignore file that seems to do the trick. I’m not trying to rip them off, but I’m incuding the gitignore file here for my own future sanity (and just in case their site goes down).

Download old 3.5 version of Unity3D

Unity 4 was released three days ago, on the 12th of November. I installed it as soon as I saw that it was available. Unfortunately, it overwrites any previous version of Unity you have installed, so I lost my install of Unity 3. To make matters worse, I could not find any download link on the Unity3d website.

Thankfully, the official @unity3d twitter account pointed me toward the installer for Unity3D 3.5. Here it is.

For PC: http://download.unity3d.com/download_unity/UnitySetup_update-3.5.6.exe
For Mac: http://download.unity3d.com/download_unity/unity-3.5.6.dmg

Enjoy.
