NAPP Texture Pack

NAPP texture pack decrypted as Not Another Photorealistic Pack allows you to plunge into a world other than Minecraft and other than realistic. Instead, it gifts you a bunch of outstanding textures, with rough, reflective surfaces, designed by a professional artist! Each and every block in the game is given special care and designed in accordance with its physical properties. For example, cobblestones have a very rough surface and no reflection, whereas diamond ore does reflect the light in areas where it has crystals. 

Here is the recommended game setup for the proper appearance of the resource pack:

1.Shader Pack Support.

The screenshots you see are taken using SEUS Renewed and BSL shader packs.

2.Optifine settings.

Options -> Video Settings -> Details -> Alternate Blocks: OFF

Options -> Video Settings -> Quality -> Connected Textures: Fancy or Fast

3.Shader settings.

Options -> Video Settings -> Shaders -> Shader Options -> Surface Options -> Texture Resolution: 512

Options -> Video Settings -> Shaders -> Shader Options -> Surface Options -> Parallax Occlusion Mapping: ON
