normal map depth question

Anty

Hi, I have 2 questions about the normalmap image.
So, after I generated the normalmap, I've noticed that in some parts of the bricks there is an "elevation"; I tried maya and xnormal, and is only a little difference between the generated textures.

The other problem is that the normalmap image does not have all the details of the high poly model, and I'm refering to the depth between the bricks.
I attached an image below.

If anyone had this problems before please tell me what can I do, thanks

I think part of that is that there's not enough tangent data on the low to capture it (that normal is casting at a 45º angle, between the two faces, if it's got 1 smoothing group), but it could be the rear distance raycast setting. You can adjust that setting in xNormal.

A normal map does not provide depth, only normal direction.

To get any sort of "real" depth you need to model the detail in the low, use a displacement map, or fake it with a parallax shader.

I would give this thread a read, it may help with your projection issues: http://www.polycount.com/forum/showthread.php?t=81154
