I'm trying to get an old-school Quake 1 look going in UE4.
I am currently using this blueprint in order to get a retro style large pixel filter.
In game (might need to zoom in to see the difference):
The look I am going for now is a low color depth (8 bit etc) that old games such as Quake had. Here is a picture for reference.
Is there any way I can reduce the color space through either a post-processing volume itself or a post-processing material?
