## Support soft masks with your custom shaders
|
|
|
|
<b>With just three additional lines,</b> you can now support softmasks in your custom shaders!
|
|
|
|
1. Add `#pragma` and `#include` directives, where `SOFTMASK_EDITOR` is an editor-only keyword and is not included in the build.
|
|
If you didn't use package manager to install, include `SoftMask.cginc` in the appropriate path instead.
|
|
```
|
|
#include "Packages/com.coffee.softmask-for-ugui/Shaders/SoftMask.cginc"
|
|
#pragma shader_feature __ SOFTMASK_EDITOR
|
|
```
|
|
2. Apply a soft mask in the fragment shader.
|
|
This operation determines the final alpha according to the soft mask buffer.
|
|
- `IN.vertex`: the clip position
|
|
- `IN.worldPosition`: the world position
|
|
```
|
|
color.a *= SoftMask(IN.vertex, IN.worldPosition);
|
|
```
|
|
|
|
As an example of implementation, please see [UI-Default-SoftMask.shader](https://raw.githubusercontent.com/mob-sakai/SoftMaskForUGUI/upm/Shaders/Resources/UI-Default-SoftMask.shader).
