Standard Default

The baseline PBR surface — a neutral white base colour (1.0, 1.0, 1.0), half roughness (0.5), non-metallic (0.0), wired with the full standard texture set (base colour, normal, roughness-metallic, emissive, occlusion) and the _NORMALMAP / _OCCLUSIONMAP keywords enabled. Opaque, back-face culled, instanced, in the opaque queue (2000). Built on @builtin::shaders.pbr. This is the starting point most materials copy and retint.

Inputs

• colors.base_color (1.0, 1.0, 1.0) — the albedo tint over the base colour texture.
• floats.roughness (0.5) / floats.metallic (0.0) — dielectric, mid-gloss default.
• floats.normal_strength (1.0) / floats.ao_strength (1.0) — normal-map and occlusion intensity.
• textures.normal_texture / textures.roughness_metallic_texture / textures.occlusion_texture — the PBR map slots, seeded with neutral defaults.
