Rendering設置
Gamma和Linear顏色空間,兩者有色差,Gamma有個2.25左右的修正值;
WebGL2.0可用的情況,只支持Deferred Render延遲渲染,且只支持Linear顏色空間;
UnityWebGL使用Video播放工具還不支持WegGL2.0;
使用WebGL1.0對shader有很大的限制,如果shader失效替換WebGL2.0,或者調低shader版本;
這里的設置還關系到屏幕后期處理PostProcessing能不能用;
OtherSetting
Strip Engine Code和Managed Stripping Level大概是什么代碼剝離和剝離等級,打包后運行出錯有可能就是這里選擇了enable;
Prebake Collision Mesh:提前添加碰撞到網格,變復雜場景加載過慢問題,空間換時間;問題;
Optimize Mesh Data:靜態分析材質,去掉Mesh中無用的數據,比如切線,多余UV什么的;但是如果有代碼動態切換材質使用法線的,打包運行會出錯,盡量也別選吧;
PublishingSettings
Enable Exceptions 是否允許打印日志,測試選擇打印,報錯會使用trycatch,至少能讓程序跑起來;
Compression Format 發布版本文件壓縮格式,如果出錯也可試試看是不是因為壓縮問題;
Name Files As Hashes 使用MD5哈希作為每個文件名,在Js中再處理也要用哈希名;
Data caching 允許瀏覽器緩存,可能需要瀏覽器權限;
WebGL模板
官方給了mini和Default模板,在Unity安裝目錄PlaybackEngines/WebGLSupport/BuildTools/WebGLTemplates/中;
可以拷貝官方的模板做修改也放在這個目錄,會在playersetting中顯示出自定義模板;
修改模板中Index.html即可;
下面是自定義做了瀏覽器自適應的模板,取消了白色加載條;

打開日志和棧信息
OtherSetting中如下,以及上述的PublishingSetting中Enable Exceptions:
Splash Image
開屏動畫,加載條,icon等素材替換;
開屏Logo把DrawMode換成順序,然后換順序放上Logo,點Preview可以預覽;
WebGL模板文件夾TemplateData下有個css,定義了加載進度條和logo格式,同時也存放了相應圖片素材,直接替換或者修改css都可;
圖標.ico也在里面,png轉ico要轉格式;
關於壓縮
選擇壓縮后必須勾選decompression fallback;
設置壓縮后,webgl無法識別內部類,也不支持一個cs文件中寫入兩個class(就離譜);
代碼剝離
dll引用
C#動態庫只能使用NetStandard2.0;高版本會報錯;
