How do you replicate rotation from client to server?

I have a camera that has a particle system attached, and a collision sphere which is the basis of where my projectiles spawn from. I cannot get the direction of the projectiles, or particle system to update when looking up or down. Left to right works fine.

This issue is extremely annoying, and I’ve tried everything i can thing of to try and fix it for 6 hours…

Is your pawn a Character-class pawn? If so do you rotate up and down using Add Pitch Input?
Characters can be tricky because they need to aim up and down without rotating the collison capsule. So it doesnt normally rotate the pawn itself.

Can you show your playercontroller class’ pitch control settings, its pitch input event handlers, and any on the pawn class youre using as well?
