In game has missing textures for the ores.
Issue is ore.json and oreblock.json in the corresponding Mod folders have the incorrect file path to "soartex_base:blocks/metal/ore/copper" and "soartex_base:blocks/metal/ore/osmium"
Should be "soartex_base:blocks/metal/ore/stone/copper" and "soartex_base:blocks/metal/ore/stone/osmium"

Should be "soartex_base:blocks/metal/ore/stone/copper" and "soartex_base:blocks/metal/ore/stone/osmium"

Are you sure to use the correct version of soartex_base and is it on 1.12.2. Because this soartex_base you use seems to have been adapted for more recent version of Minecraft with slate and nether ore background.

I see what you are saying, but that is how the file structure is built.
Yes I'm using FTB Revelation 1.12.2 from Curseforge and Soartex Fanver-Modded 1.12x.
Was using version from 11/27/20 just updated to the current 6/9/23 still the same file structure.

red360 is correct, I've verified it; extracted the 1.12 resourcepack, manually edited ore.json (TFoundation) and oreblock.json (Mekanism) to look in an additional "stone" subfolder, loaded the folder in Enigmatica2:Expert. TFoundation and Mekanism ores now show correctly instead of the default/missing texture.
