I have noticed that it dissapears.....
And i think it has something to do with the model itself...
Also the normal map wasnt really detailed look at this one for example...
It isnt the best...but this way it should do the trick..
The alien thingy used a kind of plain texture...no details in the Diffuse texture...or in the normal map.
So maybe the normal did work...but because it was to "flat" that you didnt noticed.
Also...your model polycount was a bit big...
Of course X10 can handle polycounts better than X9...
But with this type of character it was easy to optimize it.
Anyway...the FPE...textures...file types...
(oh yeah almost forgot...try to save your _D.tga to a _D.dds..
And make sure all your textures you use are DDS.
works better)
Looks all good...it should work..but i think the model itself has a problem dont know what..and dont know how to fix it.
