A free mod for Mass Effect 3, by LedGuardian.

HR Tuchanka Environmental Textures is a mod that adds many different types of environmental textures to the surfaces of buildings in N7: Cerberus Attack/Firebase Giant, Tuchanka: Turian Platoon, Tuchanka: Bomb, and Priority: Tuchanka. It was made in response to a general lack of major environmental retextures; most of what existed were upscaled versions of default graphics.

This mod revitalizes the textures of the area while retaining the desolate, apocalyptic feel of the area.

What it includes

Many of the concrete and metal textures that cover the majority of the post-apocalyptic map.
