I'm currently experimenting with building a simple set (a room with a bed, nightstand, etc) with the idea of using it to generate backgrounds for a 2D art project. I hate drawing backgrounds and I'm quite enjoying getting to grips with Blender. :)

I've run into an issue with this though, in that the "room" is basically a big cube inside of which I'm putting the furniture. It's also quite a small room so in order to create the shots I want the camera has to be "outside" the room.

enter image description here

I'm aware that in reality TV sets are built with 3 walls so that the camera can be placed where the action is to be shot from (hence "fourth wall" to refer to the audience) and I figured that'd be easy enough to do and indeed it is, but doing so involves deleting a face from the room cube.

enter image description here

If I want to move the camera somewhere else then that face needs to be put back and a different face needs to be deleted. Complicating this is the fact that at some point the room will need windows, a door, etc, and there will be posters, pictures and other decorative items hung on the walls. It'd be easy to delete a wall with those kinds of details and forget to replace it (or lose it in the undo buffer)

I thought of making each wall an object in its own right and hiding them, but this only hides them from the viewport. They reappear in the render.

I considered making a transparent material and applying it to the wall I want to shoot the scene through.

enter image description here

This worked fairly well... except that I'm also using Freestyle to create a hand-drawn effect, and apparently the big cube in the way prevents Freestyle from applying line effects to anything behind it, even if the face I'm viewing through is invisible.

enter image description here

There has to be a simple way of managing this. If so, what is it? How to I create a room with walls (and other items) I can non-destructively remove from the scene so I can view the interior, without deleting the walls entirely?

I'm using Blender 2.81a. with Eevee serving as the render engine.

You can make each wall as a separate object.
Then just disable/enable them in the Viewport and Render

Use the toggles for Viewport/Render visibility

I know this is such a basic answer... but I've already built the walls...

  • $\begingroup$ Oof, glad to be of help :). I was going to delete it, figuring you probably considered this. Good luck with your project :). $\endgroup$ – Jachym Michal Jan 28 at 22:04

    $\begingroup$ I'm pretty much a newbie to this (I've made the Blender Guru doughnut and run through a few other tutorials but this project is more or less my first project not directly based on a tutorial) $\endgroup$ – GordonM Jan 28 at 22:06
