- 'shader' property of block materials: shaders/materials/<name>.glslv, .glslf with material_vertex / material_fragment hooks and #param uniforms - material shaders code is included into main, translucent and shadows programs through generated headers, no extra draw calls - chunk vertex normal.w byte replaced with 'flags': bit 7 - emission flag, bits 0-6 - material shader index (vertex format size is not changed) - doc/*/block-materials.md
