My problem is simple. I imported a 3D object (it's not convex) and I want the character to go under your legs.

enter image description here

But this does not happen:

enter image description here

There seems to be a way to do this, I just do not know which one.

Vision of what would be a complex collision:

I've already changed all these options, but it did not work out:

The closest I got was when I saw something about adding a physical material. But when I try only a circle appears, I still can not add one exactly equal to the Character:

The collision box defined by the UE4 for any imported object will be as simple as possible.

To modify the collision box I had to follow the following steps:

enter image description here

Now just click collision and then Auto Convex Collision:

enter image description here

Now just set the parameters and then click Apply:

enter image description here

OBS - These numbers come by default, I did not put those values ​​to modify my character.

Clicking on apply you will get a preview of how the collision box is:

enter image description here

Do not forget to save!

I recommend not to greatly increase the first parameter if the third parameter is at 100000, otherwise this warning will appear. Certainly not good.

Result in game:
