1# Hard-Surface Modeling

3The execution model is in `blender-core`. Run `blender-asset-qa` after every modeling pass.

5## Pick the workflow first
6| Workflow | When | Output |
7|---|---|---|
8| **Mid-poly** (bevel + weighted normals, no bake) | modern games, props seen up close, fast iteration | game mesh directly; tiling materials/trim sheets |
9| **High → low** (high via booleans+bevel or subd, low baked) | hero assets, unique textures, tight tri budgets | `_high` + `_low` → `blender-texture-baking` |
10| **Subdivision** (support loops/creases + Subsurf) | renders, product viz, film | smooth surfaces, edges held by loops/creases |

12## Procedure
131. **Blockout** at real scale (`ob.dimensions`) from primitives. Settle the silhouette and proportions before any detail. Check against references.
142. **Apply scale** (`transform_apply(scale=True)`) before bevels, booleans or solidify, because modifier distances use object space.
153. **Primary → secondary → tertiary** forms. Booleans for cuts and panels, then bevels. Small tertiary details go in normal maps/decals, or into the high-poly as "floaters" for baking.
164. **UV the base mesh now** (mid-poly). Bevel/Boolean modifiers propagate UVs, but after bevels no edge is sharp enough to auto-seam. Then **build the stack** with `scripts/apply_stack.py -- --objects Body --preset midpoly --cutters Cut1 Cut2`. Order: Mirror → Booleans → Bevel → Weighted Normal → (Triangulate at export).
