I solved the problem. All need to uncheck the Pack Settings. Its automaticly doing it. Thank you Erikari for helping to solve my problem.(She even helped me on holiday)
All i want when i export files to PNG. I want sequential drawings as in animation timeline.
Because when i want to add this sprite sheets in unity i have to fix time one by one . If i can export the
animations in line (frame by frame) i dont have to fix in unity.
