• Performed Full Texture Parity Check:
- As of Jan 2024, four blocks were found to have different file sizes (likely because of minor differences with some of pixel color values being off by no more a single RGB value.), however, snowy grass block side was found to be based on an older texture, PBR textures have been updated accordingly to reflect the changes in its new texture & corrected many pixels.
