Masking

This package contains tools to do runtime masking of shaders via global shader properties using a moveable dome

Installing

This package is provided through OpenUPM, to install it using the CLI you can perform the following:

$ openupm add eu.netherlands3d.masking

or, you have to add https://package.openupm.com as a scoped registry with, at least, the following scopes:

• eu.netherlands3d

Usage

Add the MaskingDomeSpawner prefab to your scene.

Click somewhere in the world to move the dome directly to that position.

Drag the dome, or click on a new position to move it around.

Drag the scaling handle to resize the dome. (the initial placement scale will be based on camera distance)

Any material using the 'SphereMasking' SubGraph will be masked out by the dome.

Shaders

If you want to customise or create your own shader the following global shader variables* can be used to set the spherical mask radius and world position:

• _SphericalMaskRadius (Float)
• _SphericalMaskPosition (Vector3)

*Using ShaderGraph, you can untick the 'Exposed' box to make a variable Global (instead of serialized in the editor)

You can use the 'SphereMasking' SubGraph inside your own shader to use the premade spherical masking graph or you can create your own custom shader using the global shader variables as input.
