Help with Third Person template customization

Hi everyone! Right now I m working on an action third person game as a beginner and I would like to edit around the third person template to create the projects landscape test. However, every time I load the project and import the world fbx over top of the template, my main character fbx goes straight through the floor and the third person camera deactivates, so my main question is how do you edit/remove the static meshes such as walls, stairs etc. within the standard ue4 template and replace them with your own custom meshes and collisions. Thanks for the support!

You mentioned it, “collisions.” You need to set the collision of your new world mesh to something your pawns collision “blocks”. Just open the BP of your new world mesh and find the collisions tab under the details section when the mesh is selected. Check your pawns collision for compatibility and you should be good to go!

EDIT: Use your pawns collision bounds for collision not the mesh of your character

Awesome, I just didn’t know how to set it but thank you so much it worked! Truly appreciate the reply!
