Yes, there is only an impact sound for bullet, because it’s a projectiles pack and not a weapons pack. Different rifles may shoot with different sounds, so you have to implement it by yourself.
You can minimize shake by change settings in certain shake blueprint for desired projectiles.
About rocket - is that was an interceptor missile? Maybe it’s all because of collision settings(interceptor missiles have they own collision preset) and I’ll try to fix that in the next update.
