Yes.
though removing capsule collision by copying the CPP class and making modifications should be extremely easy all things considered.
You aren’t even removing it, you just need to change it from Spheal to a Cube or Sphere.
when you do that, some of the stuff set on it will likely break. As you compile (or try) you’ll get the errors on the lines you have to adjust.
The benefit of doing it is that all of the built in functions will still be avaliable and you can follow any tutorial you want to create movement or things you need.
Its proably a lot faster then creating a pawn with custom movement. Unless you are well versed in physics.
