Godot 4.5 + Blender完美工作流：從3D建模到遊戲部署的完整資產管道
隨著Godot 4.5 LTS即將發布和Blender 2025年重大更新，3D遊戲開發者迎來了前所未有的工具組合優勢。本文將深入解析如何建立從Blender建模到Godot部署的完整工作流程，充分利用Vulkan渲染後端、改進的UV同步功能，以及最新的社群插件生態系統。
2025年工具版本現況
Godot 4.5 LTS 關鍵特性
Vulkan渲染後端正式支援 根據最新開發進度，Godot 4.5 LTS已經完全支援Vulkan後端，提供與OpenGL相同的功能完整性和相當的性能表現：
# Godot 4.5 Vulkan渲染配置
extends Node3D
func _ready():
# 檢查當前渲染器
var rendering_server = RenderingServer.get_singleton()
print("Current renderer: ", rendering_server.get_video_adapter_name())
# Vulkan特定優化設定

setup_vulkan_optimizations()
func setup_vulkan_optimizations():
# Vulkan專屬設定
var viewport = get_viewport()
# 啟用多重採樣抗鋸齒 (更好的性能)
viewport.msaa_3d = Viewport.MSAA_4X
# 螢幕空間反射優化
viewport.screen_space_aa = Viewport.SCREEN_SPACE_AA_FXAA
# 體積霧效優化
RenderingServer.environment_set_volumetric_fog_volume_size(256, 128, 64)
print("Vulkan優化設定完成")雕刻性能改善 針對4.3版本以來的雕刻性能問題，4.5 LTS版本包含重要修復：
# 雕刻工具性能監控腳本

var sculpting_performance_monitor = {

"vertex_count": 0,
"brush_samples": 0
}
func _enter_tree():
# 監控雕刻性能

func _on_selection_changed():
