Why does shader show chars as rectangles?
I am using the shader I found by Eric Haines in http://wiki.unity3d.com/index.php/3DText
I have the following problem using this shader in Unity4---text transforms 3d testMesh to a "string" of disjoint filled bounding rectangles, one for each letter. "Good news" is these rectangles now seem correctly occluded by other meshes.
I am new to Unity but not to computer graphics. I do not yet know enough about shader syntax to see exactly how this "should" work, but am browsing some tutorials.
Attached are test images--before and after I added shader.
What I was missing was not just a shader, but also understanding
how font textures are (and can be) used in Unity. Once I found
out (recall I am new to Unity) that I could "open up" my font to
expose the font texture, I was able to drag-drop this into my new
material and then drag-drop that material onto my text and all is
good. Dennis
This is related to the texture you're using with Eric's 3D text shader. It usually happens because we can't select the default 3d text material the built-in shader for 3D text uses, so you have to recreate a font texture. Thankfully, I think Eric also provides some editor script for that.
First, read the entire tutorial Eric wrote for use with his custom 3D Text shader:

Then, realizing that you need a new font texture, use his SaveFontTexture script to create it:
Thanks for the reply. I did not realize I needed a new font texture. In fact I am not clear on what the issue is, but then again I have not puzzled out the code involved.
I have tried to follow this solution but so far without success. I believe I correctly used the script of SaveFontTexture and used it to make a new Material and applied it, but this has not changed how things look.
I am confused on a couple of things---maybe it will become clear as I continue to work on this. But the SaveFontTexture in code and comments refers to GUIText objects and but I am using (and need to use) 3d Text.
Also, in SaveFontTexture instructions, it further instructs to use some other shader from http://wiki.unity3d.com/index.php/TexturedFont. I am assuming that I am to use the 3D TexturedFont of ttp://wiki.unity3d.com/index.php?title=3DText. (None of these seems to resolve my basic problem of showing the text).
Attached are two files---one of my game in blender so you can see what I am really trying to do. Note how the frame appears in front of the green M and S. In this game I need to quickly change the letters on the cube.
The second is from my Unity version showing the problem if one uses the standard shader---see how the F and D appear to be outside the frame.
That's transparency fighting, happens a lot. Try adding 'zwrite on' to your shader passes.

Specifically my shader has this directly below 'category':
Tags { "Queue"="Transparent" "IgnoreProjector"="True" "RenderType"="Transparent" }
Blend SrcAlpha One$$anonymous$$inusSrcAlpha
AlphaTest Greater .01
Color$$anonymous$$ask RGB
Cull Off Lighting Off ZWrite On
