Storybook Fake Lighting [UE4]
A simple UE4 shading experiment inspired by Tails of Iron - I wanted to make some way of creating a scene from flat unlit (100% emissive) 2D assets that involved no actual (baked or dynamic) lights, but instead used a parameters-and-distance-based solution for tinting & brightening - as well as scaling up & darkening as assets get further from world origin's X coord.
The result, with some quick 'n dirty example art assets, through an orthographic camera
Layers - meshes get brightened/darkened & scaled based on distance from the back plane via Material
Master Material, with solutions for brightness control and scale via World Position Offset. Adjusting per-material instance values and global parameters would allow for any mood/atmosphere
Shared Material Function for calculating distance to the back wall X position & getting a value for Lerps
Optional extra functionality in a material variant for a global colour tint that gets stronger as the asset is darkened by the existing distance stuff - the foreground columns & candles in particular have a visible green tint in this shot
