3D textmesh not being drawn properly in a 2D game

Alright, I had this problem too and the only solutions i could find were SUPER complicated. Here, just attach this simple script to any game object with a mesh renderer.(C#)

using UnityEngine; using System.Collections;

public class RendererSorter : MonoBehaviour {

 void Start () {
     this.gameObject.GetComponent<MeshRenderer>().sortingLayerName = "Foreground";

//or whatever your layer name is

     this.gameObject.GetComponent<MeshRenderer>().sortingOrder = 50; 

//or whatever order you want it in the layer

}

}

It is a useful pattern to write code that only runs in the editor, Unity internally serializes many fields such as the sorting layer and order, which we can take advantage of by creating editor only scripts. This is especially important on mobile platforms, where performance is critical.

 [ExecuteInEditMode]
 [RequireComponent(typeof(TextMesh))]
 public class CONTENT_Text : MonoBehaviour 
 {
     public string sortingLayerName = "Default";
     public int orderInLayer = 0;
 
     #if UNITY_EDITOR
     public void Update () 
     {
         gameObject.GetComponent<MeshRenderer>().sortingLayerName = sortingLayerName;
         gameObject.GetComponent<MeshRenderer>().sortingOrder = orderInLayer;
     }
     #endif
 }

When you render anything gui related (text, rect, etc), you can use GUI.depth to set render priority, for example GUI.depth=0; is on top of everything.

setting my default layer to render on top seems to have fixed my issues
