So i added an obj and decided not to use it. But no matter what i do its still in my project. Took my project from 3mb to over 8mb in size with just that model. Looked everywhere, optimized....just cant seem to delete all old models. Is there a way to do so or am i stuck with them taking up all that space? EDIT: When selecting a model for an object, i UNLOCK the model that i wanted to remove and clicked on it. Hit delete button on keyboard...nothing happens. But when i close menu and re open, its now gone. However, the file size is still 8mb large. As if its still there. @NikRudenko
