Repairing windows

I accidentely painted over my windows while I was re-texturizing an outside wall. How do I get it back to look like a window? Also if I wanted to change out windows-rectangular for oval; I guess that would be a huge building project, because of walls & difference in opening? Was trying to make a regular wood house stucco/spanish. Also is there a way to copy a texture if say I have wood texture that came on house & I want to go back to that texture. How do I know where to find or is there a way to copy that to use on rest of house?
Thanks in advance for all your help!

it sounds like you have a wall that had a window texture on it
you could contact the creator to see if they would be willing to give you the texture that is missing

or if the building was copy, rez it someone else, and remove the wall from the new rez then replace the wall you painted over with the newly aquired wall

if that makes sense

i agree with the above post, The window is part of the wall texture, if you change the wall texture then the window just disapeares.

there isnt a way currently in world that will allow you to change the shape of an alpha in a texture as its created in photoshop out of world. You may have some success going back to the creature to help repair the mistake, however If you want a custom job then there may be talk of money.

Alpha'd windows are annoying. The wall becomes prone to the rendering issue when alpha textures are overlapping. I prefer using a few more prims to cut a real opening.

So the whole point is-DO NOT CHANGE THE WALL TEXTURE ON YOUR HOUSE-I don't know what kind of windows these are-I am new & bought this house a while back & just wanted stucco instead of wood on outside walls. Now the windows are "closed" & also the walls inside are the same texture as the outside.
I never built in this game-guess I am used to how Sims game works where I used to build alot-so there is no way to isolate window & put a clear texture on so it acts like a window again?

It depends on how you build it.

Low-prim buildings, designed to fit on small lots without eating all your prim allocation, will tend to use windows that are alpha-mapped right into the wall. The window is just a transparent part in the texture. But a wall built like that only needs one prim, no matter how many windows are in it or how they are positioned, for up to a 10M by 10 M wall. Once changed, you would need the original texture, or something similar, to restore the window, since it was part of the texture that you replaced.

Higher-prim, higher quality buildings will use 5 prims for a wall with one window - One prim above and one below the window, one on either side, and the window itself. Each prim can then have its own texture, seperate from the others. Additional windows of the same height can be added to such a wall for 2 prims per extra window.

Contact the maker of the house. They should be able to fix or replace it for you. Such accidents are common for low-prim builds, and a good builder won't mind fixing it for you.

You can buy textures that have a wall and a window all in one texture at texture stores like Textures-R-Us. You can also read the sticky information in the Texture Tips forum on transparency, and learn to make them for yourself.
