Hm... check if your face normals are all pointing the right way or if some are flipped. I heard that Blender displays all polygons as two-sided in its viewport by default, so you can't see flipped polygons there. Hpl on the other hand only displays the "correct" side of a polygon which can create weird holes on models with flipped triangles.
If that's not it, there could be something wrong with the UV layout. Could you post a screenshot of what it looks like in the editor now, after deleting the cache, and of the UV layout?
I'm not sure if Blender works the same, but in maya, it's best to freeze and reset transformations, then delete the object's modifier history, THEN export. It basically resets the object into a solid shape for a cleaner export. With the modifier history still on the object, it could be causing issues. Not sure if Blender can do this, but try deleting the object's history, then export.
I think that this is impossible or I dont know how do it
I now created other model and is everything good. I think this is some stupid bug;/
Nah Statyk, only maya uses that silly history system.
Paulpolska what you have in your model right there are flipped normals, AKA your polygons are turned the wrong way.

Here you go, that should help you fix the problem.

This is It and works very good. Thanks you are a god
No problem, and yes I am.
Pah! So when I say it's flipped normals, people just ignore my ramblings, but if you say it's flipped normals you're a god?! ARGH! I HATE YOU! *runs off and slams door*
Just kidding

Yea, well, I guess the rep+ difference is what changed his/her decision.
