Anyway to achieve this effect? Maybe a 2D filter

Here is a screenshot showing a nice effect…i don’t know what could be,maybe a 2d filter.
You can see that blur or fog on the distant building.I don’t know what’s that but it is a nice effect!
Is there anyway to achieve that result?

Thank you!

Fog can be setup in world options. Look at Martinsh Shaders for depth of field and bloom


In addition, there’s a bloom filter applied. There should be a resource for it…
