Hi Guys, I'm fairly new to designing but my company has trusted me with a small project. First task is to create a prototype design of the app we're thinking of developing. being a total noob and the in-house devs not telling me anything, i created the assets and all the graphics on Photoshop cc2017 artboard based on 1 resolution which is my Note 5-1440x2560. Now, they're telling me that we need different resolutions for both Android mdpi - xxxhdpi and IOS x1 x2 x3. is there a way for me to do this using my existing file or i have to do a render for each resolution, perhaps i should hand in my resignation letter? pls help thanks in advance..
