So you want to use the Tiled plugin to gain more control over your mapping but just aren't quite sure how to get started or might be scared you would break something? No worries! I've created a video tutorial to help you get started with the basics! It's nothing fancy, has me stuttering in a few places because I have the occasional brain fart and I even failed to get the map saved properly until about a minute afterwards, but it should still help you in getting started.
Please forgive the not-so-great audio quality and my general derpiness.
As an added bonus, when I get the chance, I will update this video to have more in-depth information. Right now, working with limited time, this was the best I could do, but I will update it later.
Note: The current version of the Tiled plugin is for 1.3.0+, meaning it works for any version of RPG Maker MV from 1.3.0 and above. So yes, you can use it in 1.5.0 without any issues. It's the version I'm using for the video. It can be seen when I bring up the plugin manager.
