Outline system uses URP Render Objects features attached to forward render to apply an outliner material (Scripts/Graphics/OutlineMaterial.mat) with custom shader (Scripts/Graphics/OutlineShader.shader) to objects on particular layers (Intractable and InteractableHeld)

The object currently being held by the player is set to the InteractableHeld layer to increase the intensity of the outline
