Packed Fonts (Experimental)

Packed fonts allow you to use the "Pack chars in multiple channels" feature in BMFont. When this is enabled, each channel of your texture (4 channels in a 32 bit image) stores an independent set of glyphs. This means that you can have 4x the number of glyphs in a single texture - a 2048x2048 texture can store the equivalent amount of data as a 4096x4096 texture.

Set-up

1. Export your font from BMFont, ensuring you have Bit Depth set to 32, and Pack chars in multiple channels is ticked in "Export Options".

2. Set-up this font as you would normally - you can't currently import the font into a sprite collection.

3. Switch the shader on the material to tk2d/Goodies/PackedTextMesh.

4. Use the font as you would normally, but keep in mind the limitations listed below.

Limitations

• Packed fonts are currently not allowed in sprite collections.
• You can't change colors on packed fonts, but you can use the gradients feature to achieve similar results. Of course, you'll need a shader to enable this...
• Only supported with programmable shaders, and not in fixed function.
• The shader overhead is slightly higher than normal shaders.
