Can you postt a pic of what is happening. Because I d/led the file I uploading and it shows up fine in modviewer.
Is this happening to anyone else?
I just tried it again in mod viewer. It looks fine.
I don't know what it might be. Make sure that all the bitmaps are still 512 X 512. Also try this. Back up the original files.
Then copy all the regular maps over the i-maps. So over write saucer_i.bmp with saucer.bmp. Do that with all three.
See if there is any difference.
I don't think this is a lighting problem. Otherwise it would manifest on my system as well.
