占坑
lightmapper有兩種: Enlighten, Progressive
Enlighten:
baked GI 靜态物體 離線烘焙
precomputed GI 也是适用于靜态物體
F是預先計算的 light相關資訊可以實時改變 更新有延遲 幾幀後會更新完
性能和resolution有關
動态物體接受的來自靜态物體的indirect light 用probe 模拟
可用于 skybox emissive light對周圍環境的影響
Precomputed Realtime GI
Create Geometry
Layout Systems
Create Systems
Create Atlas
Clustering
Visibility
Light Transport
Tetrahedralize Probes
Create ProbeSet
這個是Precokmputed realtime GI的計算流程,能看出來就是在算F 每個cluster的系數
probe要自己去放
The difference is that while lightmaps store lighting information about light hitting the surfaces in your scene,
light probes store information about light passing through empty space in your scene
light probe存的是光在空間中的路徑上影響因子的比例 和cluster的f一個意思 隻是沒有hit
Progressive lightmapper
lightmaps
Light Probes with progressive update 漸進式更新 對實時gi都有一定程度的支援
