Vehicle stopped being able to climb incline?

Hello,

I am working on a game based on the advanced vehicle c++ template with a vehicle blueprint pawn (based on the c++ class). Yesterday during dev I must have inadvertently changed a setting somehow and the vehicle can no longer climb even the slightest incline.

Comparing all vehicle customization to a backup from the start of the day I can spot no differences (weight, max rpm, etc). Worst case scenario after a little more debugging I’d just go back to the backup and lose a few hours, but I am curious if this sounds “exactly like X” to someone that could point me in the right direction.

Symptoms:

  • Level terrain max speed is reduced
  • Steering feels like there is no weight or gravity being applied, despite mass remaining the same
  • Passing full constant throttle can’t manage to climb slight inclines without practically crawling to eventually roll backwards (down the slope)
  • Vehicle seems more prone to tip/flip and higher speeds

Any ideas? I am sure it’s something I did that I can’t spot. I wasn’t even tweaking vehicle settings at the time but managing components placement in the pawn.

Thanks!

Could friction have been what was altered? Perhaps the gravity of the world?
