Flashbombs do not blind the player

Instead of it, only the 2D UI screen is affected and I see a white square at a front of me.

As I see, required effect already implemented in the game. In FM "Requiem" view is going to white color when the player meets a ghost of the Builder priest. You can check it right at the beginning - just leave a starting home.

Can you use this effect to flashbombs?

The problem is that the vast majority of screen effects in TDM are implemented with UI controls - and unfortunately they are technically indistinguishable from real UI controls, so there's no way to automatically determine which need to go to the UI layer and which don't. And even if they were to go to the eyes, if they have some kind of pattern (like blood spatter), they will look really weird in the eyes because they will not quite match up between the eyes.

So, will have to look into it, but unfortunately this is going to be one recurring problem that simply does not have an easy technical solution.
