Multiplayer Map Design - Animating Materials

Since the end of Unit 70, and finishing up my basic thematic lighting, I have been tasked with implementing 3 different instances of animated light sources into my map. I have been shown examples of animated lighting, including flickering lights and animated 'sprite sheet' style lighting.

Mandatory:

Flickering Lights:

The use of flickering lights I feel will best suit my level, being set in an abandoned warehouse type building in a post war environment, there is room to add a feeling of faulty electrics within the building.
The flickering lights may be used to mark certain pickups or bonuses, for example the rocket launcher within my level which players must fight over, could have a flickering light above, drawing in players to maintain fast game progression.

Post Processing Volumes:

I have a plan for a post processing volume within my level, to be implemented simply covering the upper tier of my map, this will have a darker colour lookup table to dim the light in the upper tier, giving the effect that there is less light higher up, the users on the lower tier of the map will not be affected by the change and will still be able to easily see enemies on the walkways above.

Lens Flares:

I must add a lens flare to my level, providing another source of animated light, these consist of four parts, with the values edited to render at set distances from the player, a lens flare will be added to my level and will be set accordingly with its surroundings.

Optional:

Flipbook Textures:

Flipbook textures are an optional extra to be added into my level if I feel they will fit, at this moment in time I do not see a direct use for a flipbook texture, but this may change, if so one will be subsequently imported into my level.
