Custom armor model texture not working

I'm trying to make a space helmet for a space suit armor, and the model looks good in blockbench, but when testing the mod, the texture does not look right. I've searched for so long to find an answer but it lead me nowhere.

This is how it is supposed to look like: https://imgur.com/ElHY11f

This is how it looks like in-game: https://imgur.com/7qxK6eL

I don't know what to do, please help me.
