Realistic Game Engine 3D Models

You must be familiar with Unity Game Engine. I will give you 3D model files in FBX format that will include textures. These are ai generated 3D models. You will then need to edit these 3D models(or recreate them) but use the ones I give you as the reference. You will also have to create new textures based off of the provided models. So for example the textures from the ai generation give an idea, but are not quality enough for game engines. The styles are realistic, and the models are of objects, buildings, and environments.

For someone skilled in blender this should be very easy work.
