How to Make a Window?

I’m looking for a way to create a cube that can project whatever’s behind it, like a window. Something that could be used without having to create a new mesh for whatever the window would be used to see through. I’ve been trying to create this effect using a Render Texture, but I can’t seem to find a way that makes it work well.

You can create two cubes in a cross pattern or make a 3d model of a window, because that would be much easier.

Please take a look at this page.

If you are using a texture on the cube, the texture image needs to have an appropriate [alpha][2]-value.

If not, you may simply do the following:

  1. Create a cube.

  2. Create a new material

  3. Set the Material of the cube’s “Mesh Renderer” to our new material.

  4. Set the material’s Rendering Mode to Transparent

  5. Change the alpha-value of the material’s Albedo colour

By changing the material’s alpha value, you can make it transparent/semi-transparent.

If you want a windows inside your cube, as you write in your comment above, you could create a texture for your cube and let part of the texture be transparent (by changing the alpha values at that part of the texture)
