So, tonight I loaded a tree object (.obj) and saw it was laying on it's side. I rotated the tree by -90 degrees, made a few other changes and then saved as TGO. But when I reload the TGO file the tree is laying on it's side again. Went through this process a second time, and again the tree is laying on its side upon reloading the TGO file.
Is this expected behavior for TG4?
