Big with transparent textures

Hey,

I made this model for a minigame I am making with the team I am in and there are some glitches/bugs.

This is in Cubik Studio

As you can see some textures are NOT getting rendered behind the transparent elements

Do you use a transparent blockstate?

This is z-fighting.
Items in Minecraft are rendered double sided. That means transparent elements can have invisible faces in Cubik visible in game.

In Cubik Studio be sure to remove hidden faces (with automatic optimisation or manually)

The hidden faces of the transparent voxels or the ones of the solid voxels?
