How can I improve lighting in my game?

PolyFarm is cozy farm simulator.

do you have shadows enabled

it doest look like it

also post processing would make your game look much more decent, even tho it doesnt have much to do with lighting as you asked

give it a try and see

I have a day/night cycle in my game, with point lights on specific objects. I could easily see a blinking yellow light on top, some headlights when harvesting at night, and some tail light glow via emissive materials.

it is, but shadows dont work on field texture

it's on

There's a lot of different post processing overrides to use, depending on what you want artistically
Rather than something that's either on or off

Cozy warm look.
