TextMesh Pro TextMeshPro unable to reference/display a font asset loaded in asset bundle

Hi,

I have a prefab built of game objects that have the Text Mesh Pro UGUI script on it. The script is referencing a font asset.
This prefab is a part of an asset bundle called "menus".
This font asset is part of a directory which belong to an asset bundle called "fonts":

During editor time, the font asset is displayed correctly along with its material presets:
But during run time, after asset bundles are downloaded, the preset selected is incorrect (the default preset?/default font asset?).

I have already tried taking the font asset out of the "fonts" directory (which belongs to an asset bundle) - didn't help.

Any help/suggestions are highly appreciated!

(Using Unity 2017.4.1f1)

 

Did you find a solution to this problem? I'm having the same issue

 

For whatever reason, I missed this initial post. My apologies for that.

See the following post about this http://digitalnativestudios.com/forum/index.php?topic=878.msg11814#msg11814

Please let me know if this resolves your issue.

 

Thanks, looks like my issue was that the shaders were both in a resources folder and an asset bundle, my fix was to just remove the shaders from the bundle and leave them in the resources folder and it 'seemed' to work (for now)

 

I'm having the same issue.
Using Unity 2018.2.0f2 - 2018.2.6

the same problem??

That is the shader reference that is missing. When you load the bundle, you will have to manually re-assign the correct shader to the material used by those font assets. If you are using the same shader on all text objects, that is trivial to do as you load the bundle.

I realize this is an extra step. Hopefully at some point this will no longer be necessary.

 

Hello, I'm struggling with the same (visually) issue. But it shows itself ONLY on MacOS builds. Windows and Android works fine. Also it is only the TextMeshPro compoenent, that has a problem, all other objects inside the bundle are rendered fine. The TextMeshPro component in the bundle uses the same shader I use for some other TextMeshPro objects in scene (that are not in the bundle) and they are rendered fine.
I use this script to reapply the shader after I instantiated the prefab from the bundle into the scene (do it for all the prefabs from the bundle):

Code (CSharp):

1. private void ReapplyShaders(GameObject go)
2.     {
3.         foreach (Renderer rend in go.GetComponentsInChildren<Renderer>(true))
4.         {
5.             Material[] materials = rend.sharedMaterials;
6.          
7.             for (int i = 0; i < materials.Length; i++)
8.             {
9.                 if (materials[i] == null || materials[i].shader == null)
10.                     continue;
11.  
12.                 string shaderName = materials[i].shader.name;
13.                 Shader shader = Shader.Find(shaderName);
14.  
15.                 if (shader != null)
16.                     materials[i].shader = shader;
17.                 else
18.                     Debug.LogWarning("Shader " + shaderName + " not found!");
19.             }
20.  
21.             rend.materials = materials;
22.         }
23.     }

and here is the Player.log from the MacOS build

Help me, Obi-Wan Kenobi. You're my only hope.

 

Issue:
Had this too.
When TMProUGUI was loaded via asset bundle.

The text was not visible, It lost its TextAsset.


Solution:
Instantiate it and set the TextAsset for each child with the TMProUGUI component.
(based on the approach by
@vladk )



GameObject myGameObject = GameObject.Instantiate(current.gameObject, targetParent);
ReapplyTextAsset(myGameObject);

Code (CSharp):

1.   private void ReapplyTextAsset(GameObject go)
2.     {
3.         foreach (TextMeshProUGUI txtMeshPro in go.GetComponentsInChildren<TextMeshProUGUI>())
4.         {
5.  
6.             txtMeshPro.font = _FontAsset;
7.  
8.         }
9.  
10.     }

 

I am having this issue, but only on assets brought in by one package. I have other packages that come in and render their text mesh pro assets just fine... any ideas? or am I just to replace all TMP materials as they appear, regardless.
