Make Blocks Look Realistic Using Sakura Prime Shader's PBR Support

Sakura Prime Shader supports PBR (physically based rendering). Surfaces can react more realistically to light, but only when the textures supply the extra material data. Vanilla textures don't include that data, so you need a PBR-ready resource pack to see the effect.

Adding a PBR resource pack

1. Get a resource pack that advertises PBR, normal maps or specular maps.

2. Open Options → Resource Packs → Open Pack Folder and place the pack in the resourcepacks folder.

3. Move the pack to the Selected side and click Done.

4. Keep Sakura Prime Shader active under Video Settings → Shader Packs.

Seeing and tuning the effect

• Stand near stone, metal or polished blocks during the day. Then rotate your view slowly. Surfaces with PBR data should catch and shift highlights as the angle changes.
• Check again at sunset or near a light source. The ACE tone mapping keeps strong highlights from blowing out, so bright reflections should still look controlled.
• Open the shader's settings by clicking Shader Pack Settings with Sakura Prime Shader selected. Look through the menus for lighting or material options and make sure anything related to PBR or materials is enabled.

If blocks look flat or oddly shiny, the resource pack may use a PBR format the shader doesn't read the same way. Try a different PBR pack, or remove it to return to clean, flat textures.
