Turning Down Screen Shake on Stromberg Car Missile Explosions

I am trying to reduce the screen shake caused by the missiles launched from a Stromberg vehicle. I have tried streaming the explosions.yft file (with the screen shake turned down on EXP_TAG_ROCKET) and another explosions.meta file (turned down screen shake on EXP_TAG_SCRIPT_MISSILE) and had no luck.

Maybe I streamed the .ymt wrong? I used the EXPLOSION_INFO_FILE data type for both in the fxmanifest.

If you know how to do this it would be greatly appreciated
