Is it possible to have a depth of field effect using particleSystem only?
I tried to play with depthoffiled parameters but particles are either all blurry or all clear but it never depends on their position in the world.
Here is a playground which shows the problem: https://www.babylonjs-playground.com/#49XARW#3
See line 60 to play with the depthoffield parameters.
However the motion blur effect is working as you can see in the example.
