I´m actually trying to make a specific post process in my game.
So, what I want to achieve is a degraded blur, I´ll explain it, my game is a 2D game, and I want to make “layers” with diferent focusing, the first layer, where the player is 100% focused, the next layer with one type of buildings 70% focused, and the last layer with other kind of buildings 40% focused.
I put here a graphic of it:
I´m pretty new in it, and I don´t know if gaussian are better than Bokeh to achieve it and what parameters touch.
getting the parameters right depends a lot on your scene setup, but using the depth of field is the correct approach for what you want. bokeh and gaussian use different blur kernels for a different look at different performance costs and with different parameters to tweak.
