Hello,

I am a fresh newbie in the world of Unreal Engine and I’d like to ask for your help for something!

If you take a look at the attached pics, the DoF effect on the glass window in the contour of the headrest (the focal point) is incorrectly rendered.

I’d like to know how to correct this problem.

​I understand this happens because the DoF in unreal engine is a post processing effect.

Is there any way to ray trace the depth of field and have physically accurate effect?

Thanks!
