hi folks. there is some bug or something with PS (all updated). so, it goes like this, when i open file mockup everything works, i can draw, move, rotate 3d objects etc etc. After i open .psb file, that document is empty, although it shouldnt be cuz there is few layer in it. I cannot do anything, i dont see anything, just black main screen (canvas). On the right i can see layers with content but cannot do anything but to close the file. When i come back to original file, then it all stop working. Cannot do anything, cannot move, rotate, draw etc etc...Also when i try to open any other file, it doesnt work. So the only solution is to restart PS. And then works ok but only if i open simple files without 3d smart objects...If i open again files with 3d objects, same problen appears..
