Thanks Jacky for your help. For the first time when the compile error pops up; never experience anything like it. My first reaction was to go check “Blueprint folder” and compare with another working “Project Folder”; right away I knew something happened because the “Blueprint folders” of both "Project Folders"looks different. LOL!, I am sitting there wondering what’s going on?;why now?;what did I just did and when?.. it was funny, but I wasn’t laughing because the assets exported from Max took some time including laying out the level in UE 4.3. First intelligent thought is always 99.99% correct, in my case to do a fresh “Project” > move your assets > case CLOSED!. I am sure there are other approaches to fix the issue but I took the easiest…also learn a lesson to pay attention.
