Problem with initializing filters

Troubleshooting effects
1

I have a class that extends rigid body control. I use it so that I can modify every fired objects trajectory and to stop it when it hits something. I was testing bloom effects on my fired objects and it worked ok, I just initialized filters once in the main class and added material and rigid body control to the fired object. Now I was trying to add bloom only when a object hits a target, and that required me to initialize filters in my class that extends rigid body control, and I did so. Problem is when I fire multiple arrows my fps drops and it starts lagging. I know its because I initialize filters more than once, so I need help to understand how to do this. I know its because of initializing filters because I tried initializing filters multiple times in my main class and it caused lagg same as this.

Can you post how you are doing it presently?

}[/java]
Also have a problem when I shoot an arrow and it collides sometimes it rotates backwards, so the pointy end is sticking out. I think its because when the arrow hits a object it manages to bounce just a little bit and game rememberes that location and then rotates the tail towards it(you can see in my code that my arrows rotate so that the latest location is remembered and then the tail is rotated to that spot), so I need a way to stop the arrow in the exactly the same time it hits an object, or a little bit earlyer.

Create 1 fpp and bloom filter in simpleInitApp.

Tnx, now it works. So simple. I dont even get how it works.
