This is odd. There doesn't seem to be any logical reason for getting a big hole (its grey on the normal map) right there. Its identical to the other side on both the low and high poly.
I've tried using both XNormal and Mudbox to render the normal map. It appears as a large dent in the Mudbox version.
I've tried fiddling with various settings in both programs notably using the "cage" method and cranking the ray distance up to ridiculously high levels, neither of which solve the problem.
I've done a bit of reading but theres a lot to go through. If anyone could give me a hint as to what exactly is going wrong here it'd be nice.
Cheers.
