The rotrBLOCKS HD texture pack is a PBR/POM resource pack that retains the original style, making the game graphics even better!
The rotrBLOCKS resource pack (1.21, 1.20.1) is regarded as a PBR/POM (Physically Based Rendering/Parallax Occlusion Mapping) texture pack that retains the original style while improving visual effects. It doesn't take away the style of vanilla Minecraft, but makes it look more beautiful and realistic. Overall, this means that blocks will have more depth, with richer surface detail and greater bumpiness. Additionally, this resource pack helps beautify the transitions between blocks, making the entire environment look more harmonious and aesthetically pleasing.
