2D view export doesn`t work resulting in a full black image

So recently I can`t export 2d view, no errors. Substance just exports full black images instead of 2d view. First export is always fast and i get the black image. Next exports take forever and the result is the same..My global settings are the same. I tried changing env map, tried diff padding, nothing works. No errors in the log also. Version 8.1.2 build 1782
