NaughtyAttributes is an extension for the Unity Inspector.
It expands the range of attributes that Unity provides so that you can create powerful inspectors without the need of custom editors or property drawers. It also provides attributes that can be applied to non-serialized fields or functions.

{
}
// Check for Multiple Tags
if (_enemy.HasTags(_allEnemiesTags, allRequired: false))
{
}
// Adding Tag
_enemy.AddTag(_zombieTag);
// Removing Tag
_enemy.RemoveTag(_zombieTag);
Here are two useful effects for the built-in renderer. They’re not new, but I’ve used these both in Unity 2019 and they still work fine:
Screen space multi-scattering:
Basically fog with depth-based convolution. The convolution imitates the way that light scatters through water droplets, so it looks much more moist and steamy then depth fog. Regular depth fog has no scattering, so it looks more dry and hazy in comparison, like dust in the desert.
Volumetric lighting:
Blender Unity FBX:
This is actually a Blender plugin, but extremely useful if you use Blender with Unity. This will allow you to export a blender model to FBX that’s actually compatible with Unity’s Coordinate system. This is especially useful for character models when you want to do procedural animation or something.
