I think the issue is that a PE Entity isn't a viable object in vanilla Minecraft, so you would have to export it as an Optifine item with a JPM format. Sorry if I'm incorrect here, it's my best guess as I'm not particularly familiar with Optifine and PE Entities.

Hoping this is something that might actually be possible, but need to know for sure. Right now I'm working on a few Minecraft models that are larger than 16px, so they go out of the center grid area. Not a problem in and of itself, except that every time I try to do a UV Snap, it treats every part ...

That sounds like that may be part of it, since I was using colored glass as the base texture. I'll try adjusting a few things based on your suggestion, thanks! :)

EDIT: That was 100% it, for sure. I put the model on a non-transparent block, and it immediately fixed the issue I was seeing. Thanks ...

However, going into third-person, you can clearly see the issue I'm having. The front/top of the model seem to go ...

The ones near the camera. They're supposed to have a solid back, but you can see right through it to all the layers of the image.

Also, i don't really understand how culling is supposed to work, so it might be that. I'll read up a little bit about that, at least it's something for me to look into.

So, I keep having this odd issue with my models in-game. When previewing them in the creator, they look just fine. But once I try to use them in-game, I keep seeing THROUGH the layers of the model. It's noticeable in first-person mode, but when in third-person it's absolutely ridiculous. I attached ...
