So, TECHNICALLY this isn't out for 1.16.3, but it does run; and when it does...packages render weird.
It's not consistent, but they seem to use utterly random textures, including flower textures of all things.

Going to close this issue because it's very old and I don't have the time to support 1.16 anymore, I hope you can understand.

Ah dammit I must have broken something with the update that made it work better with Canvas; basically redid the whole model system. Thanks for the report, i'd like to try and make it work on as many 1.16 versions as i can.

Can you post some screenshots and send a mod list? sometimes other mods can interfere.
