Just like I said the past 5-6 responses. I also linked you 2 webpages, that you didn’t read apparently.
You just simply don’t fire your projectile from your muzzle but from your camera. That’s it. Seperate FX and actual projectile physics.
If you want to see a working example, download the C++ Shooter Example, it features both aimed and hip fire with crosshairs.
Maybe I am stupid and there indeed is another way. At least, I looked into the Shooter Example source and didn’t see projectiles being shot from the CameraLocation, so chances are there might be some other way I don’t know of, just look into it
