Why does my Character fall through the mesh?

I was having issues creating a level for my character to traverse in Unreal so I made one in Blender and imported it but for some reason the character falls through the floor of the mesh even though it’s supposed to have a collision box. I tried giving the mesh a complex collision box but that didn’t work either, any suggestions on what could be wrong?

What type of blueprint are you using for the mesh?

Try to put it a little higher over the ground, if that doesn’t work, can you send a picture of your mesh collision and your collision filter?

I actually figured out the issue, since the whole level was one big object it was acting as one latge collision box amd pushing out the character
