General Settings

Light Map Resolution 光照貼圖解析度
Generate Mesh Distancde Field 產生網格距離場（一種不怎麼消耗效能的陰影）
http://api.unrealengine.com/CHN/Engine/Rendering/LightingAndShadows/MeshDistanceFields/index.html

LOD For Collision 用於複雜的碰撞網格LOD，不會隨距離變化而改變

Specifies which mesh LOD to use for complex (per-poly) collision.
Sometimes it can be desirable to use a lower poly representation for collision to reduce memory usage, improve performance and behaviour.
Collision representation does not change based on distance to camera

Lpv Bias Multiplier 一個很新的渲染技術

Light Map Coordinate Index 光照貼圖座標索引？？

Distance Field Self Shadow Bias 距離場自身陰影位移
可以調整距離場陰影的濃度

Useful for reducing self shadowing from distance field methods when using world position offset to animate the mesh‘s vertices

Support Uniformly Distributed Sampling 支援勻均分布採樣
網格支援在固定時間內均勻分布的採樣。
記憶體成本為8位元組每三角形。
執行個體使用是均勻產生的粒子。

Mesh supports uniformly distributed sampling in constant time.
Memory cost is 8 bytes per triangle.
Example usage is uniform spawning of particles.

Allow CPUAccess
如果為真，將保持幾何資料CPU可訪問的烘培產生，而不是上傳到GPU記憶體。釋放它從CPU記憶體。
如果希望在熟能產生的運行時訪問CPU上的StaticMesh幾何資料（例如，將StaticMesh轉換為Proce.lMeshComponent），則需要這樣做

If true, will keep geometry data CPU-accessible in cooked builds, rather than uploading to GPU memory and releasing it from CPU memory.
This is required if you wish to access StaticMesh geometry data on the CPU at runtime in cooked builds (e.g. to convert StaticMesh to ProceduralMeshComponent)

LOD For Occluder Mesh
指定哪些網格LOD用作軟體遮擋的遮擋器幾何形狀。
設定為-1不使用此網格作為封堵器

Specifies which mesh LOD to use as occluder geometry for software occlusion
Set to -1 to not use this mesh as occluder

Positive Bounds Extension 正邊界擴充
Negative Bounds Extension 負邊界擴充
Asset User Data 使用者資料資源
儲存使用者資料數組和資源，例如UDatasmithAssetUserData，UAnimationModifiersAssetUserData，繼承UAssetUserData

Array of user data stored with the asset

Collision
walkable slope override
walkable slope Behavior
walkable slope angle
