Light Without Shadows

Oh, sorry, I didn’t understand what you meant until I looked at the default Third Person map in which it has an animated 2D help item. I looked at its blueprints and now I understand that I need to put the color directly into the Emissive slot. Thanks

I still don’t know how to change a whole map to Emissive without doing every single piece manually, and that’s the most important part.

I don’t understand what a “lit buffer” is. I Googled it and couldn’t find anything. I also don’t know what “AO” means.
With the “skylight” option, if I attach a light to each player, how do I make the light uniform? As in not super bright close to the light and fading with distance. Also, does it pierce through walls unobstructed?

I want my game to be lit up fully, with zero shadows. All shadows completely disabled, and all light completely disabled, so the game uses the least possible memory in that department.
