Window Tinting Problem

Each time i put in window tint script in texture that has windows built into building, the wall also changes to tinting, can someone tell me how I can add the script without the building wall changing

Are the windows separate objects, or are they simply painted into the texture of the wall?

Without seeing the script, it's of course impossible to know what it's doing, but here's what's most common. If the windows are each a separate prim from the rest of the wall, make sure you put the script into the window prims, not into any other part of the wall. You might even need to unlink the windows from the wall. It all depends on how the script is written.

If the windows are just part of the wall texture, then you're going to have to come up with a different solution. SL has no internal texture editing capabilities. You can't have a script change the color of just one section of a texture. All it can do is apply a color multiplier to the entire surface or not. One solution would be to make a few different versions of your wall/window texture, with a different color scheme painted into each. The script would then simply flip through them, rather than making any actual color changes.
