feat: performance budget profiling setup
- docs/performance-budget.md: 60fps/2GB VRAM budget with CPU, GPU, memory, and draw-call targets (P95<16.6ms, P99<50ms) - scripts/profiling/: SceneTree + Node profilers, test scenes - scripts/generate_occluders.gd: auto-generate OccluderInstance3D from CSG wall pieces (128^3 voxel occlusion culling) - scripts/convert_csg_to_mesh.gd: CSG->StaticMesh baker with LOD slots (LOD1@15m, LOD2@30m) - project.godot: occlusion culling + LOD settings enabled - modular scene UV2 data from lightmapping pass - rcon_command_handler.gd conflict resolved (kept upstream plugin cmd) - Fixed profiler_node.gd warmup frame bug (60 frames, not 3) - Fixed convert_csg_to_mesh.gd LOD API (add_lod + distance)

# CSG → Static Mesh Baker with LOD generation.
|
||||
#
|
||||
# Converts all CSG pieces in the current scene to MeshInstance3D nodes
|
||||
# with proper LOD levels for the final optimization pass.
|
||||
#
|
||||
# This is the definitive LOD solution: once meshes are baked, Godot's
|
||||
# built-in mesh LOD system takes over via the Mesh resource's LOD slots.
|
||||
#
|
||||
# Usage:
|
||||
# 1. Open target scene in the Godot editor
|
||||
# 2. Scene > Run Script (select this file)
|
||||
# 3. Choose whether to replace CSG in-place or save meshes separately
|
||||
#
|
||||
# The script:
|
||||
# a) Finds all CSGShape3D nodes (CSGBox3D, CSGCombiner3D)
|
||||
# b) Calls mesh_to_save() to get the generated mesh
|
||||
# c) Creates MeshInstance3D + CollisionShape3D replacements
|
||||
# d) Generates LOD1 (50%) and LOD2 (25%) via mesh simplification
|
||||
# e) Replaces the CSG node with the baked mesh
