Dear Esenthel,
My Orthogonal view doesnt work in the model editor. I load my mesh, I click view, then I click Othoganal. everything is black. my character model doesnt show up. I even tried some of the default character models that comes with the engine. everything is black. character doesnt appear like it does in your tutorial. Maybe I'm doing something wrong. But I'm starting to think this is a bug.

Yes it's a bug, I'll fix it asap.
