blender is actually pretty awesome. it has a ton of features and functionality, its professional grade, and its free. i will agree that its different from ue4 but that is because they are two very different types of software made for very different purposes. blender is modeling software for creating assets but can also do things like animation, image editing, and compositing. ue4 is a game engine made for combining parts into a game, it has no actual modeling function, there are bsp brushes but thats the limit of the modelingish functions.
