2.6.1 - Dynamic Fonts - Changing the Material

[Ferazel]

Sorry if I missed this, or even if this is possible or not. I'm switching over to dynamic fonts in 2.6.1. However, I'm running into a problem. I want to use a custom shader for the dynamic font that uses backface culling. It seems that Unity automatically creates a material and texture object in the project hierarchy when the .ttf font is set to dynamic.

I created a new material, and set the texture property on the material to the texture that the dynamic font generates. Regardless if I drag and drop or select the new material, the UIFont automatically resets back to the Unity Dynamic font material. Is there a reason why this behavior is not allowed? Is there something that I'm missing?

Seems like if we can't use a different material/shader than the default one, dynamic fonts are significantly less useful.

You can. You just have to make your own material and use the generated texture from the font inside that.

Hi Nicki, that's what I tried, but the NGUI UIFont doesn't appear to accept the new material. I have attached some screenshots. Have you tried to do this under 2.6.1 and it works properly?

I tracked this issue down to the material property in UIFont.cs

Summary: There is some special case code in the get that handles dynamic fonts, but there was not logic in the set for that same special case. I simply added the extra else if at the end there.

code:

1. public Material material
2. {
3.         get
4.         {
5.                 if (mReplacement != null) return mReplacement.material;
6.  
7.                 if (isDynamic)
8.                 {
9.                         if (mMat != null) mMat.mainTexture = mDynamicFont.material.mainTexture;
10.                         return mDynamicFont.material;
11.                 }
12.                 return (mAtlas != null) ? mAtlas.spriteMaterial : mMat;
13.         }
14.         set
15.         {
16.                 if (mReplacement != null)
17.                 {
18.                         mReplacement.material = value;
19.                 }
20.                 else if (mAtlas == null && mMat != value)
21.                 {
22.                         mPMA = -1;
23.                         mMat = value;
24.                         MarkAsDirty();
25.                 }
26.                 else if (isDynamic && mDynamicFont.material != value)
27.                 {
28.                         mDynamicFont.material = value; 
29.                         MarkAsDirty();
30.                 }                      
31.         }
32. }
33.

And that works fine without any issues? Font's material is not something you can change on the TTF font itself, which is why I didn't include a setter for it. The correct change would be:

1.                         else if (mMat != value)
2.                         {
3.                                 mPMA = -1;
4.                                 mMat = value;
5.                                 MarkAsDirty();
6.                         }

ah, i wasn't sure about the premultiplied alpha line, so i did not include it in my post. Thanks for the correction

[maoguo.zhang]

Sorry! I also need to change the font's material. Could you tell me whether my change is correct?

   public Material material
   {
      get
      {
         if (mReplacement != null) return mReplacement.material;

         if (isDynamic)
         {
            if (mMat != null) mMat.mainTexture = mDynamicFont.material.mainTexture;
            return mDynamicFont.material;
         }
         return (mAtlas != null) ? mAtlas.spriteMaterial : mMat;
      }
      set
      {
         if (mReplacement != null)
         {
            mReplacement.material = value;
         }
         else if (mMat != value)
         {
            mPMA = -1;
            mMat = value;
            MarkAsDirty();
         }
         else if (isDynamic && mDynamicFont.material != value)
           {
               mDynamicFont.material = value;   
               MarkAsDirty();
           }
      }
   }

Just update, it's already a part of 2.6.1b.

[galuodo]

Just update, it's already a part of 2.6.1b.

Is it possible that we can set the filter either?

[ArenMook]

I don't understand the question.

[galuodo]

the filter mode of texture of font's
Text shows well in point mode

[maoguo.zhang]

Just update, it's already a part of 2.6.1b.

I got 2.6.1c. But the isse which was raised by Ferazel still exists. Is there anything that I'am mising?

[maoguo.zhang]

Only I have this problem?

[ArenMook]

It seems it's still broken in C. I will fix it in D.

[ganqiang87]

Use dynamic font, a large number of Chinese when the android will be messy.But are good for the win and ios
can you fix it？
you can see  one is ok，Another is not ok
