Hi, I’m trying to map texture to my model in zbrush - so the moddel is standard mapped with GUVtiles, and the’re no errors in mapping. Then I aplied a map with resolution 6000x6000 and dropped into projection master (only color ,fade on or off). When Im’drawing on my obiect everything is ok, but when I drop it back, something bad happens (as on the images below). The same thing when I’m using zapplink. What schould I od? 
Please help!
not sure but your texture res is wayyyyyy too high, 6000x6000 is equal to 36million polygons. for a head like this i would say you’d be safe with either a 1024 or 2048, but really don’t need higher. try that and see if your problems continue. Also try AUV tiles.
Turn Draw>Perspective off if you have it on.
but this is not only a head - this is a part of a body 
aurick!! thank you! thats it!
