MoreMcmeta does not function for any custom content. Only works on base Minecraft content.

[Xethas]

In version 1.21.1 this does not work with any textures that are not base game minecraft textures

Steps to reproduce the behavior:

1. Set up file structure for resource pack for small custom mod.
2. Load up resource pack and verify custom texture replacement load so file structure is correct.
3. Add a test.png.moremcmeta file for a test block texture which is currently replaced with the resource pack
4. MoreMcmeta does not load any of this content. This mod works with base game minecraft content, but I need this to work for anything else

Expected behavior:
Any effects are applied properly to paths outside base game minecraft

Which mod loaders does this bug affect?
Fabric

Mods list
Just a small custom mod adding blocks, this mod and the emissive addon mod

Resource pack
Created a singular block replacement pack with just two files in the location/format:
assets>modid>textures>block

test.png
test.png.moremcmeta

contents of moremcmeta file identical to the one that works for base game excluding path:
{
"overlay": {
"emissive": true,
"texture": "modid:textures/block/test_e.png",
"transparency": "translucent"
}
}

Also tried using the demo texture file content and overlay png with the same result:
{
"overlay": {
"emissive": true,
"texture": "modid:textures/block/obsidian_overlay.png",
"transparency": "translucent"
}
}

Tried a variety of different texture paths in the event it was just not navigating properly with no luck. At my wits end trying to get this to work
