Limitations - Ticxo/Model-Engine-Wiki GitHub Wiki

Model Engine is not a mod. It is a plugin built with vanilla mechanics. In other words, there are limitations as to what you can and cannot achieve.

• Each model inside a bone still obeys the law of Minecraft item models. Meaning it cannot be larger than 48x48x48, 80x80x80(R1.0.6+), or 112x112x112(B2.0+), and rotation can only be -45, -22.5, 0, 22.5, and 45.
• Teleportation might not be exact. Even though it is accurate on the server-side, there are client-side limitations that mess up the rotations and positions. Model Engine will try to eliminate as many errors as possible, but there is only so much it can do.
• Lags. Model Engine utilizes the flexibility of armor stand's rotation. Each model consists of multiple armor stands, which will cause lag to the players and the server.

If you think these limitations are affecting your server and user experience, this plugin might not be for you.
