Surfaces of mesh not loading correctly in Gazebo

I have created a cave mesh using Blender and exported it as a Collada file as shown here:

However, when I load it in Gazebo the floor doesn't appear, and so, if I try to put a robot in the cave, it falls:

Does anyone know why this is happening or has a clue on how to solve it?

Thank you!

Did you add the mesh as both visual & collision?

Another thing to check is the normal's direction, but I doubt it also affect the collision.
