[1.12.2] Translucent Block Not Rendering Properly in Hand

[RileyTheFox]

I've tried looking around through Google and various threads on here but it always seems to be the opposite to the problem I'm having. I made my own glass-like block and everything works correctly besides the rendering when it's in a player's hand. The block itself works fine and I like how it looks but in the hand it's acting like the texture is completely opaque. I tried looking at similar blocks like stained glass but I can't seem to figure out what the issue is. I'm probably missing something totally obvious but that's why I wanted to ask here to see where I'm being dumb.

 

So this is how it looks in game:

 

And I'm getting this weird effect when in third person with the block like it's trying to render it translucent but it's not quite there:

 

Lastly here's my .json files for the block and item models. If I need to post the code, let me know. I just didn't know if I did.

 

Here's the block model .json:

{
  "parent": "block/cube_all",
  "textures": {
    "all": "fallenstars:blocks/shimmer_glass_red"
  }
}

 

And here's the item model .json:

{
  "parent": "block/cube_all",
  "textures": {
    "all": "fallenstars:blocks/shimmer_glass_red"
  }
}

 

Sorry ahead of time if I'm just being dumb with something obvious. It's been awhile since I've coded and I'm trying to reacquaint myself to it but I've run into this dilemma along the way.

 

Thanks so much in advance for any help.

I apologize for trying to bump my own thread. I just haven't heard back this weekend and assumed it got missed. Could really still use the help here as I'm still rattling my brain on it trying to edit the jsons  and whatnot but nothing is working.
