Question About UVW Unwrap Tool - NWMax

[Legacy_Pstemarie]

                I'm finally reskinng my moathouse with a single wall texture, The texture is 512w x1024h. When I use the unwrap tool it compresses the texture so it appears as if its 512 x 512. Is there anyway to get the UVW Unwrap tool to display the texture so its using its actual size? 

The mapping is coming out ok so far, but I have to keep bailing out to see how it looks like in NWNEXplorer and verfiy that's what I want it to look like. Its a hassle to say the least.
