Would it be possible to add support for the mod NetherEx? It adds nether biomes, and the netherrack tendrils don't show on their versions of netherrack (Fiery, Icy, Lively and Gloomy), and as far as I can tell there's no way to add them. (nex.block.BlockNetherrack, metadata 0-3 if that matters)

Also, there's a Mycelium-like fungal netherrack called "Hyphae" in the mod that could use the grass texture. Added it to mine manually. (nex.block.BlockHyphae)

Kind of added support in 2.1.8. I'll leave the issue open for two reasons:

• The colors of the vines don't match with the custom netherracks well. I'll see if I can do something about that.
• I've used the 1.10.2 version of NetherEx, and messed up the mycelium whitelist a bit. It was called nex.block.BlockMycelium before, update it to nex.block.BlockHyphae in newer versions.

Hey, I realize this is an older thread, but this is fairly related. I was disabling some stuff in my configs and noticed that you have the entry nex.block.BlockNetherrack under the Netherrack Whitelist. NetherEx recently changed their mod name from nex to netherex. You may have already fixed that, but it seemed an easy thing to overlook so I thought I'd mention it. :)
