Usage with TextMeshPro
To use SoftMask with TextMeshPro, import a sample asset.
- For Unity 2019.1 or later
- Open
Package Manager
window and selectUI Soft Mask
package in package list and clickTextMeshPro Support > Import in project
button
- Open
- For Unity 2018.4 or earlier
- Click
Assets/Samples/UISoftMask/Import TextMeshPro Support
from menu
- Click
The assets will be imported into Assets/Samples/UI Soft Mask/{version}/TextMeshPro Support
.
NOTE: You must import TMP Essential Resources
before using. They include shaders, fonts, etc.
NOTE: If the shader error is not resolved, reimport the shader. Or, import the TextMeshPro Support
again.
Support soft masks with your custom shaders
Only a few steps are needed to support soft mask in your custom shaders!
- Duplicate your shader file and add the
(SoftMaskable)
suffix to the file name.
Your_Custom_Shader.shader
-> Your_Custom_Shader (SoftMaskable).shader
- Modify the shader name (defined at the beginning of the shader file) as follows:
- Add
Hidden/
prefix - Add
(SoftMaskable)
suffix
Shader "UI/Your_Custom_Shader"
-> Shader "Hidden/UI/Your_Custom_Shader (SoftMaskable)"
- Add
#pragma
and#include
directives, whereSOFTMASK_EDITOR
is an editor-only keyword and is not included in the build. If you didn't use package manager to install, includeSoftMask.cginc
in the appropriate path instead.
#include "Packages/com.coffee.softmask-for-ugui/Shaders/SoftMask.cginc"
#pragma shader_feature __ SOFTMASK_EDITOR
- Apply a soft mask in the fragment shader.
This operation determines the final alpha according to the soft mask buffer.
IN.vertex
: the clip positionIN.worldPosition
: the world position
color.a *= SoftMask(IN.vertex, IN.worldPosition);
As an example of implementation, please see UI-Default-SoftMask.shader.
