Bitmap Custom Atlas Shader

The Bitmap shader is designed to use bitmap-only fonts. It treats the font atlas like a regular texture, displaying it directly, and does not support any text effects. Bitmap-textured text becomes blocky when you zoom in on it.

Properties

Face: Controls the text's overall appearance.

Debug Settings: Exposes internal shader properties that are sometimes useful for troubleshooting.

Face

Description

Property:		Description
Color		Adjust the face color of the text. The value you set here is multiplied with the vertex Colors you set in the TextMeshPro component. Set this to white to use the original vertex colors. Set this to black to cancel out the vertex colors. Similarly, setting the Alpha to 1 uses the original vertex-color alpha, while setting it to 0 removes any alpha set in the original vertex colors.
Texture		Apply a texture to the text face. The texture is multiplied with the face Color and the vertex colors in the TextMesh Pro component to produce the final face color. The Horizontal Mapping and Vertical Mapping properties in the TextMesh Pro component determine how TextMesh Pro fits the texture to the text face.
	Tiling X/Y	Increase these values to repeat the texture across the text surface, in accordance with the TextMesh Pro object's Horizontal Mapping and Vertical Mapping properties.
	Offset X/Y	Adjust these values to change the texture's relative position, horizontally or vertically, on the text surface.

Debug Settings

The debug section exposes some of the shader’s internal properties. They can be helpful for troubleshooting problems you encounter with the shader.

Property:	Description
Font Atlas	Points to the atlas texture used by the font Asset.
Offset X/Offset Y	Offset the vertex positions of each character in X and Y. You can change these values using a script to create simulated crawl or scrolling FX.
Softness X/Softness Y	When Mask is set to Soft, set these to adjust the softness of the edge of the text.
Clip Rect	Clip Rect defines the Left (L), Bottom (B), Right (R) and Top (T) world space coordinates of the masking rectangle. This is normally set automatically by the 2D RectMask. However when using a normal TextMeshPro component, this allows you to set / control the masking region.
Stencil ID	The reference value. For more information, refer to the ref parameter in ShaderLab command: Stencil.
Stencil Comp	A comparison operation. For more information, refer to the comparisonOperation parameter in ShaderLab command: Stencil.
