A20 Textures for Corpseblocks

[Zolokhan]

I have been using this mod https://7daystodiemods.com/new-terrain-textures/ (specifically the dead leaves) for corpse blocks ( i have been modding them back in since they removed them)  .. it works good and is nice and dark.  With A20 i cannot get that mod to work.  

 

Can anyone help with either :

1) Telling me i am missing something with that mod and showing me how it works with A20.

2) point me towards some new textures mods so I can shop for a goreblock texture.

3) Magically make me a goreblock texture lol -.-
