I think you should post some screenshots and informaion about wich program you need to view your models. ;)

Hi, the screen shots is a high model for generate the normal map texture for the low poly(i have it in other computer,when i can i send some images or download the visor) like a bump map.
Edit--with/without normal maps. model low around 2400 triangles.

What resolution is the baked normalmap? It looks like it is rendering properly in the viewer, but it is blurry like it is too low resolution to capture all that fine bumpy detail from the high-res model. Can you post a JPG of the normal map at true-resolution?

I think you'll need a 1024x1024 or higher to capture all that fine detail. Most game normalmaps don't have details as small as that on your model, because the normal map has to be too big to reproduce it properly.

u should check your uvs!

Here's a reply I made in the polycount forum not long ago...

Using auto-generated UVs is a no-win situation. All those UV seams balloon your in-game vertex count, since you're duplicating UV verts all over the place. And I've yet to see an auto-generator that doesn't waste a ton of texels, so I can't see how you get better resolution from it.

Too many wasted/empty unused pixels. Better to create quality UVs and use those to bake the normals.
