How do I change an imported model of a room to display 2-sided walls?

I’m new to Unity 3D (and pretty new to programming). I’m working with a modular indoor environment builder from the asset store.

I’m trying to get the outer walls to display as well. However, since I didn’t create the model or the materials, I don’t have the shader source, so I can’t do the “Cull off” thing that I’ve read about everywhere (or can I? Someone correct me on this if I’m wrong please.)
The mesh consists of the whole room as a single piece, so I’m not sure I can duplicate and invert just a wall without also duplicating the rest of the room. (Besides, I’m not sure how to “invert” at all; any direction on this would be appreciated as well.)

I’ve found a lot about editing built-in shaders, and about creating my own meshes to be two sided, but since this shader is not built-in, and since the meshes are prefabs of the whole room, I’m lost. Help!

I don’t think making a 2-sided shader will work how you think it will. Have you ever glitched a camera in a game and seen an “inside out” face, for example? Thats the sort of thing you’d get. Also, drawing the back will be slow, theres a reason its culled.

Your solution will be to get an outside for the room, or link it together with other rooms to create an indoor environment. From the sounds of it, the package sounds like its designed for creating indoor environments.

If you want to cut it up and make your own room, you’ll have to open it up in a modelling program and cut it up. I personally have no idea about that, since it is outside my area of expertise.
