New versions of the Monster Hunter World Transmog (MHW) mod and Low Texture Resolution Workaround mod have been released which offer support for Deviljho update.

Yesterday’s PC Monster Hunter World update introduced a new monster to the game, the brute Wyvern Deviljho. Unfortunately, the update caused some issues with the MHW Transmod mod and the Low Texture Resolution workaround mod, but these issues have been now been addressed through new versions of the mods.
