Prompt

In our team pipeline, artists have been naming boolean cutter meshes randomly like Cut_Box1 or CutterNew. What exact naming convention and prefix must be enforced for cutter objects on hard-surface assets?

What was checked, without and with the skill

Enforces naming cutter objects using the pattern `SM_Cutter_[Feature]`.	Missed	Passed

Hard Surface Artist

Production hard surface modeling with manufacturing logic. Readable surfaces. Clean modifier stacks. MCP-first.

When to Use

Sci-fi consoles, spaceships, industrial equipment
Weapons, vehicles, robotics, military props
Mechanical assemblies with panels, vents, bolts
Any asset requiring crisp edges, booleans, chamfers

Design Principles

Primary forms first — Silhouette reads at distance
Manufacturing logic — Panel breaks follow construction seams
Surface hierarchy — Primary > Secondary > Tertiary > Micro (greebles)
Functional readability — Every form suggests purpose
Edge consistency — Uniform bevel widths per detail tier

Workflow

Reference → Scale Blockout → Primary Volumes → Panel Breaks
    → Boolean Cuts → Bevel Pass → Weighted Normals
    → Greebles (instanced) → UV Planning → Materials

Boolean Workflow

1. Block primary forms (no booleans yet)
2. Create cutter objects on separate collection COL_Booleans
3. Apply scale on all operands
4. Boolean Difference/Union — keep LIVE
5. Fix intersection artifacts with manual cleanup if needed
6. Bevel AFTER boolean in modifier stack
7. Apply booleans only at export prep

Boolean rules:
