In need of help with NORMAL maps.

Hello,

I need help. I don't know where to go, during the weekend I watched all the youtube and cgtuts videos on this matter, and still don't get good results... I don't understand and can't figure out what I'm doing wrong.

I have a big problem with normal maps.

I will start from the start: what I have did.
I´ve modeled a model in 3ds Max in high poly, pourly detailed, then optimized it to low poly level: 2100 polys (something like that).


After optimizing I´ve unwraped the model and packed it. So that the maps would be easiely editable.

Here is the unwrap:

After that I have made exploded bake of the normal maps, and it seemed to be ok, but when I apply the map on the model with directX shader here is what I get.

Here is the normal map:

If you look closer to the map, you will see that the bolts didn't render as wanted... They should be straight. Anyone ones why it could happen? P.S. This is a copy of the map, I tried the same with the maps in .png format ant .tga

This is what I want to get with the help of normal maps:

Also, my collegue told me that the normal maps doesnt work in Unity engine. Can anyone tell me the reasons? Because this is my first experience in low poly models and game engines.

Just noticed, that this map really don't want to work with shader's, got them to work only with diffusebump shader. Don´t work with normal map shader.

PLEASE PLEASE HELP

Thanks a lot of the help,
