Scatty/Jumpy NavMesh Movement Question/s

Hey guys, hope this makes sense and sorry if you get it alot am new to Unity and Game Design/ Game Programming!

Anyway, I started making a 3D RPG, I have done a few Scripts for Movement, Camera Controlling and "ClickToMove", I have wonderful movement with the Keyboard so long as NavMesh isn't involved, my Click To Move could be improved, i.e to not need a NavMesh, maybe even removed completely - I'm not sure yet! My camera script works perfect again, without a NavMesh. However when I add a NavMesh it all goes tits up, my Character is stuttering, jumping, sleeping and controls become awfully "scatty". I can re-obtain my WASD and Cam scripts to perfection via removing NavMesh and CTM Script, however I'd like to sort this out and keep all the options available.

I can post my code and a video of what I'm talking about if need be? Anyway, was wondering how to go about solving this, I don't know what the actual term is so google has been rather vague, tbh I would be happy with an 'Offical' term to google at this point lol.

 

hm, I don't think it is a good idea to add navmeshagent to camera
