As a workaround, you can disable MSAA and use FXAA instead, until the issue is fixed. To do this, select `Main Camera`, and in the ***Inspector*** view of the Camera component, in the ***Output*** section, set MSAA to `Off`. If you would like to use FXAA, in the ***Rendering*** section, set the Anti-aliasing option to `Fast Approximate Anti-aliasing (FXAA)`.

The purpose of this piece of code is to obtain a random float Parameter and assign it to the light's `Intensity` field on the start of every Iteration. Let's go through the code above and understand each part. The `FloatParameter` field makes it possible for us to define a randomized float Parameter and modify its properties from the editor UI, similar to how we already modified the properties for the previous Randomizers we used.

Notice there is a `RequireComponent(typeof(Light))` line at the top. This line makes it so that you can only add the `MyLightRandomizerTag` component to an object that already has a `Light` component attached. This way, the Randomizers that query for this tag can be confident that the found tags are attached to GameObjects that also have a `Light` component, and can thus be Randomized.
