Hmm... Are you the developer of the texture pack mod? If so, I can add a Call in a future update to allow other mods to modify its textures.

If it's just a regular texture pack or you're a texture pack player, I'm sorry, but the way the mod is implemented doesn't allow it to adapt to other texture packs. However, you can disable Revengeance Mode and Death Mode, which will make it try to use vanilla textures instead. That should help your textures show up :)
