can't render image sequence

One or more jobs in the queue have an unsaved map as their target map. Maps must be saved at least once before rendering, and then the job must be manually updated to point to the newly saved map. so what do you mean target maps?

everything is saved in my project, why can’t i render?

Can you give a little more information on what your issue is here? You have a saved level and level sequence that won’t render?
