effect not applied on player camera

Hi I have a problem in my unity test template...

basically i set the post process grain effect to be on when player enter trigger( to simulate radiation zone effect)
and scirtp works fine but my problem is that grain is not applied to the player wepaon camera as shown in the picture

how can i solve this?

i'm using wo camera a main camera and a weapon camera pn unity 2018.2

 

Have you tried applying the Post process script on to the player camera inside the game object?

 

Hi !
Try applying the effect on the weapon camera only, it should then apply on both.

 

thanks to both for your answers but how can i apply the effect only on the weapon camera?

i have aset a post process profile in my gamemanager and another in Maincamera..

i need to set another in wepaon camera?

 

many thanks.. i added the post process profile to weapon camera and disable that one on the main camera and all worked fine

another question i have for standard image effects...i would to have a sepria tone applied at ceratin conditions and i added the effect to the weapon camera and disable it at start since i want to call it manually.. but i red the documentation and cannot figured how to call effect when i want..
