How does transparency work?

[random pumice]

On the left I have a model I have created replacing a lectern, and on the right I have a model replacing a tripwire hook, but on the left, the handle thing, [zoomed in on in second picture] does not show transparency, yet on the right, the tripwire hook does. If it makes my confusing sentence easier to read then the model on the left is based off of a core from portal 2 and on the right is a fizzler from the same game

Transparency is unfortunately only supported if the base block uses transparency in one of its default textures too.

(Unfortunately something hardcoded and not a model setting)

oh okay that makes sense, I need to find a block that already has transparency then, thanks
