null ref finding a shader

BinaryCats

in code:

public static Material BoneMaterial {
   get {
      if (_boneMaterial == null) {
         #if UNITY_4_3
         _boneMaterial = new Material(Shader.Find("Particles/Alpha Blended"));
         _boneMaterial.SetColor("_TintColor", new Color(0.4f, 0.4f, 0.4f, 0.25f));
         #else
         _boneMaterial = new Material(Shader.Find("Hidden/Spine/Bones"));
         _boneMaterial.SetColor("_Color", new Color(0.4f, 0.4f, 0.4f, 0.25f));
         #endif
      }
      return _boneMaterial;
   }
}

line _boneMaterial = new Material(Shader.Find("Hidden/Spine/Bones"));

keeps giving us a null ref in editor view when we have selected a spine object. This only happens with one object, which has no visable slots in set up pose. Don't know if that is an issue or what

Did you partially update your runtime?
The Spine/Bones shader (which is an editor shader) was recently moved to Hidden/Spine/Bones. A few versions ago, maybe.

Updating Bones.shader might fix it: spine-runtimes/Bones.shader at master · EsotericSoftware/spine-runtimes · GitHub

That shader does exist. however we have to alter it, because you guys don't do depth correctly. or something, I didn't re-write it

ITs because of the hidden stuff... but we have never had to do this in the past ? :/

Bones.shader was never meant to be used for games. It's an editor shader Mitch made for SkeletonUtility to draw bones in the inspector.

Just change the path/shader name.

BinaryCats

... So what shader are you suppose to use? skeleton shader?

Pharan

The code you quoted was the editor code for SkeletonUtility scene view bones that Mitch wrote. That in particular was meant to use the Bone shader. It just lost the path because you updated SpineEditorUtilities.cs but not the Bone.shader. Really, only the shader path changed between that code and the shader code.

You can use whatever shader makes sense for your game, of course.
You can make a copy of Bones shader code if you like to use it for games. You know what's best for your graphics pipeline.
