I've done some terrain texture tests using DXTbmp, but the result hasn't been satisfactory.
Here's what I've done:
I open a default CFS3 city terrain dds texture in DXTbmp and use "Send to editor" - which is PSP in my case - and save it as bmp without doing any changes.
In DXTbmp I select Export Alpha channel and save it as another bmp.
Then I open the first bmp in DXTbmp and then select "Import Alpha Channel" and save it as a dds dxt3 file format since DXTbmp shows that the default
terrain texture was in that format. The "new" dds file looks OK in DXTbmp, exactly the same as the original texture and also the transparency looks
But when I check in CFS3 ETO Expansion the new texture looks like this:
Close to my plane it looks OK but further away the texture becomes very blurred. In the top of the picture you can se the difference very clearly where the edited texture meets another city texture which is much sharper at that distance.
I also tested Pat Pattle's BoB city textures and they suffered of the same problem. Very clear close to the plane but very blurred further away.
What is the reason the textures get that blurry in game? What have I done wrong?
