AI 產生的概覽

指導透過 MCP 工具在 Blockbench 中建立與設定供 Minecraft 基岩版 RTX 使用的 PBR 材質。

功能: 此技能說明了一組用於在 Blockbench 中建立、設定、查詢、匯入與匯出 PBR 材質的 MCP 工具。它說明了 color、normal、height 與 MER 紋理通道，以及金屬度、自發光、粗糙度與次表面散射等材質屬性。它也提供石頭、金屬、玻璃與發光方塊等常見材質類型的範例，以及以匯出 texture_set.json 作結的完整方塊材質工作流程。
適用情境: 適用於處理 texture_set.json 檔案、製作法線、高度或 MER 貼圖，或為 Minecraft 基岩版 RTX 設定材質屬性時。也適合在 Blockbench 中建立多通道紋理工作流程。
執行需求: 需要 Blockbench 並提供所引用的 MCP 工具（create_pbr_material、configure_material、list_materials、get_material_info、import_texture_set、assign_texture_channel、save_material_config，以及紋理與筆刷工具）。匯入與匯出會使用檔案路徑。此技能不附帶指令碼，僅為說明文件。

MER Texture Format

The MER channel packs three properties into RGB:

R (Red): Metalness (0=dielectric, 1=metal)
G (Green): Emissive intensity (0=none, 1=full glow)
B (Blue): Roughness (0=smooth/shiny, 1=rough/matte)

Creating MER Texture

# Create blank MER texturecreate_texture: name="block_mer", width=16, height=16,  fill_color=[0, 0, 204, 255]  # Non-metal, no glow, 80% rough
# Paint metallic areas (R channel)paint_with_brush: texture_id="block_mer", coordinates=[{x: 8, y: 8}],  brush_settings={color: "#FF0000", size: 4}  # Metallic spot
# Paint glowing areas (G channel)paint_with_brush: texture_id="block_mer", coordinates=[{x: 4, y: 4}],  brush_settings={color: "#00FF00", size: 2, blend_mode: "add"}

Tips

Normal maps use tangent space (blue-ish color, RGB where B is up)
Height maps are grayscale (white=high, black=low)
MER channels can be painted separately or as a combined texture
Use list_materials to see what's available
Always test in-game with RTX enabled for accurate preview
Roughness 0 = mirror-like, Roughness 1 = completely diffuse
