Hi @BioCoder,
I accomplished this on my Thirdperson Template by modifying the Camera Boom arm length while the Player was sprinting. Im not in my dev machine so I cant pull the BP nodes, but I think I ended up using FInterp to from the “Standard Arm length” to the “Sprint Arm Length.”
You can see the results here:
Feel free to download the template and copy the code yourself to suit your needs.
Hope this helps!
