The problem of making large terrains

我正在尝试创建一个大型场景。在测试地形的过程中。发现了一些问题，希望有人能帮助我 我测试了用4X4，总共16快1000X1000单位的terrain来拼合成一张大的terrain。当我在这个地形上生成tree之后。整个unity变得非常慢 I'm trying to create a large scene.W$$anonymous$$le testing the terrain.I found some problems. I hope someone can help me I tested using 4X4, with a total of 16 units of terrain of 1000X1000 to make a large terrain.When I generate tree on t$$anonymous$$s terrain.The whole unity becomes very slow

我发现其中有一个prepare scene culling parameters占用了我的很高的资源。 后来我直接创建了一个4000X4000的terrain,也生成了很多树。但是并没有出现之前Editor界面响应变慢的情况。 希望有制作过巨大场景经验的哥们，能传授一点在unity中解决这些问题的方案 I found that one of them, prepare scene culling parameters, takes up a lot of my resources. And then I created a terrain of 4000X4000 directly, and I got a lot of trees.But there was no slow response to the Editor interface before. Hopefully, those of you who have worked on big scenes will be able to teach unity a little bit about how to solve these problems
