I ve got a problem with my max 2013 (in 2010 it didnt happend)
normal map made in zbrush same as unwrap(flipg,tangend and adaptive selected for map in max, ofc it was flipped V)
also i made normal in xNormal but its the problem is in max, btw when i change shader for any other color normal map disappear from preview
i bet its some noob question but i cant handle it by my self
