uh... whom ever told you that is horribly wrong because every single one of my renders uses Conquest. The only thing it doesnt show are addons to blocks being like green fuz on leaves(which requires optifine a mod not resource pack). (which i think is the only block specific extra conquest has) but no matter you can use whatever resource/texture pack you want ever as long as it is the right mc version otherwards it uses old textures for new blocks.
