If you've spent much time working in perspective, you know that drawing a good grid is one way to save tons of time. These grids, though, aren't much fun to draw. This video introduces you to some free software created by Epic Games which will make the experience much more pleasant. I'd only recommend using this software once you're able to draw grids manually, but it's free and offers a huge time savings. Thanks Warren Marshal, you've made my life a lot easier! Here's a link to the official page and download at Epic Games.
