Unity3d recently doing micro side load, a deadly problems, such as title, I don't know which master more to the same question, or to do resource dynamic loading, how to avoid such problems appear when the scene is always to be baked or really ugly

CodePudding user response:

What unit of game resources? Scene? Prefab? Material? Texture?
Pro, ask something the more clearly describe the problem about good

CodePudding user response:

Hello, I also encountered this problem, the scene dynamic loading baked out of the shadow of the lost, do you solve

5. X is will trouble later, this is also the official offer, you need to load the following script on the prefab
