Hi gap,
thanks for your reply. Here is the other dds-file:

With the "other plates" i mean these (for example), they seem to be individual plates:

I followed your advice and saved the dds as you said, but when saving i got the message "image width and height must be multiple of four". Indeed the dds-files have all the width of 2047. I boldly changed it to 2048, but then in the game i get this:

So the area the game takes for the plates from the file is now double the width as before. I used a clean copy of the file. Are you sure with choosing "Generating MIP-Maps" and not "Using existing MIP-Maps"? I am not an expert in this, certainly you know what i did wrong...
