How to use datasmith imported object from C4D as a mesh object in blueprints

Hello… I created an airplane in C4D, and imported it in Unreal (4.25) with the datasmith importer. Now, i’m trying to have it fly around with a blueprint. Right now in the blueprint I am using a cube to visualize the animation, but how can I use my datasmith object instead of the cube (it won’t let me replace the mesh object nor add it as a mesh object.

thx!
