Editing Static Mesh shapes

I’m trying to get a grasp for UE4 by modifying existing material to see what happens. For example, I changed the Eggs in Tappy Chicken into a ball using the Source TGA Texture. The Mesh however stays Egg Shapped. How would I go about Changing the Egg’s Mesh?

Edit: These forums don’t seem to like the Plural for “Ball.”

As they are just meshes, just import another shape which you have created in a 3d program like blender, 3ds max, maya,… and then just put the texture onto it and add it to the bp


I see, thank you.
