I'm making the rounds to mod threads that have texture support in Soartex, a 64x resource pack. Would you mind adding a link to Soartex texture support to your OP? We've been shipping our graphics for your mod for ages.

We also created a java program that installs patches to resource packs. A patch for your mod is in there... And our modpack resource packs have graphics for your mod as well.

While I'm here, I might as well mention John Smith Technician's Remix has support for your mod. Both Soartex and JSTR survives on contributions to their Github repositories.
An immense amount of work has been put into these textures over the last 2-3 years, but we haven't been very good at sharing them with the mod creators. People might enjoy the free textures artists have contributed for your mod.
