What kind of house assets do I need for a top down view fade out feature

Hello everyone, I’m new to game development and for my first game I want it to be a Top-down isometric view game. I’ve got a question about fading out the building walls and ceilings when they’re between the camera and the player. When making my buildings in blender should I split the house into separate walls, ceilings etc. or will that not be a problem or can I set it in Unreal engine? Thank you

It is better to make your house modular ( separate parts ), and that things that would really have thickness, like walls, do actually have thickness.

Apart from that, this top down view stuff, is done in the material. There is no fixed way of doing it, because it depends on a lot of things. Tutorials all over youtube, of course
