Modder ‘HalkHogan’ has released a new version of his HD Texture Pack for The Witcher 3: Wild Hunt. This new version of his project fixes some LOD issues with the rocks, making them look more natural than before. In addition, the new textures for rocks are much more optimized.
Furthermore, the modder has reworked and increased the resolution of the Toadstool textures from 256×256/128×128 to 1024×512/1024×512.
