How to load model with texture at runtime by unreal engine

I am new to use the unreal engine. However, it really makes me frustrated.

What I want to do is simple: load model and texture it at runtime, change its position and rotation, then render the scene. I searched online, and find several plugins may related to loading model at runtime. runtime mesh import export plugin, or RuntimeMeshLoader. The 'runtime mesh import export’ can not be installed on my mac. And the ‘RuntimeMeshLoader’ only work with the mesh part. ****For now, i haven’t found a solution to simply load model with texture. This really makes me confused: loading object and its texture is a basic step for 3d operations. For example, panda3d can do it well by just a load_model() function.

What I needed is to load some models (not static, each time the model list may change) and put them in the scene, then render. Anyone help here?
