Here is a before and after view of the problem. I am trying to change the recessed box image which is stored in the window_piece01.tga file. Anyway, what i'm doing is creating a 41x41 image the way I want it, and super-imposing it over the image emedded in the window_piece01.tga. The problem is, after I save the window_piece.tga file into my custom directory, and re-view the part I altered is corrupted, as seen below.
Anyone have a clue what the problem is? I noticed, when viewing the properties of the default file, that there is a mask saved to the file, but I can't figure out what it would be. I'm not changing any area the would have a transparency, i'm taking up the exact same space the normal image does. /boggle
The left image is how it is supposed to look, the right image is how it looks after I save it.
