I am having a problem with my exports. Has anyone had this issue. I have tried restarting and copying geometry to new model. Is this a graphics card issue? I have a GTX 1070
You've got Vray installed, haven't you? It's a problem related to Vray. Search for 'Vray gray bars'. You'll find plenty of info.
You can try resetting the camera in Advanced Camera Tools.
thank you very much!!
