Mob Animation Problems

Before I begin I'd like to say I'm using v1.8.2 of MCreator!

So I've decided to begin working on creating custom mobs for my mod! Fun right? It actually, for the most part at least, is! I'm just having one issue, and it's with setting up the basic animation.

So when I first imported the .java model into my workspace, it asked me to set up the basic arm/head/leg movement! I did that and when I finally had my mob loaded into the game, I noticed a weird issue. Basically the arm "joints" (Where the arms were waving from, was at the bottom of the arm, at the paws, causing the shoulders to basically flail around as the creature moved around. I thought it may be because I used 3 different cubes to create the arm, but I also had the same issue with the legs (And they only had the single part to them). They were moving from the feet rather than from the "waist" area. I'd show a screenshot, but it's incredibly hard to get them in motion.

Here's My Mob's Code, the .java model was made with Blockbench! Arm2 is the left arm, and Arm1 is the right arm. Same format follows legs. I'm clueless as to why this issue is happening, so any explanations would be great. My one guess is that I have to manually change the 24 in the ".setrotationpoint" as shown in the snippet below, but I have no idea what I'd have to change it to for it to work properly!

Thank ya for the help! I'm hoping this isn't a bug with this version of MCreator so that I can get some crazy cool mobs working right into my mod asap!
