Asset Port v1.6.0

Overview

AssetPort v1.6.0 introduces Static Mesh LOD Automation (supporting embedded FBX groups and separate _LOD# file chaining) and Smart Nanite Automation with intelligent polygon density heuristics and blend mode safety guardrails.

Key Improvements & Bug Fixes

• 📐 Static Mesh LOD Import: Automatically imports embedded FBX LOD groups and attaches separate _LOD0, _LOD1, ... files to standard and Atlas Static Meshes (PR #20 by @skywa1keri7).
• ⚡ Smart Nanite Automation: Intelligently evaluates mesh polygon density against a configurable threshold (nanite_min_triangles), automatically enabling Nanite on dense opaque meshes during post-import.
• 🛡️ Nanite Safety Guardrails: Automatically skips meshes with custom LOD chains and Masked / Translucent blend modes to prevent overdraw and rasterization artifacts.
• ⚙️ Configurable Optimization Parameters: Added smart_nanite and nanite_min_triangles parameters to importer_config.json and ImporterSettings.
• 📊 Pipeline Metric Tracking: Added lods_imported metrics to console summaries and dry-run preview simulation reports.
• 🧪 Expanded Unit Test Suite: Added tests/test_smart_nanite.py bringing test coverage to 15/15 passing unit tests.
