In versions 1.7.10 and 1.8.9 my model renders incorrectly, with all translucent textures being made solid as seen below:

In versions 1.10.2 and 1.12.2 a similar issue occurs, with solid objects inside my model not rendering through the translucent parts:

the intended behaviour is as seen below, with solid parts of the model rendering inside of the translucent parts, this occurs properly in all versions 1.16.5 and up:

i think 1.18 also has a transparency issue too
