How to optimize Unity3D tree species more

Divide the big scene into many smaller scenes. Load terrain separately from buildings.

For example, if there is a large scene, take out its terrain separately and divide it into 10 small scenes. Then load the buildings on the scene with ** dynamically.

When you enter the first scene, load the second scene connected to the first scene, when you are about to go to the second scene, show the second scene, and use ** to load the buildings in the scene, then hide the first scene, and load the third scene at the same time. Then if you walk towards the first scene, the first scene is displayed again, and the third scene can be destroyed. And so on.

First, in real projects, you generally don't directly import a complete scene into Unity3D, as @周华 said, because this will increase the difficulty of culling and occlusion, and you can't import the whole scene as a model, which may affect efficiency. Clause.

2. If you want to import the scene to the unit.

Export the model to FBX or OBJ format, and then upload it to the Laozi cloud platform for one-click optimization.

You click on your trees

There are settings to set the height and size of your tree.

In the Hierarchy tab of the Draw Tree Model, click Create Tree to create a tree model, set the closure macro to set your own tree model, here we first import the tree model that comes with the system, and then discuss the production of custom models. Because there are no tree and grass texture elements in the new car, they can be found in the Unity3D standard library.

If you take a screenshot of the interface you are operating, it may be a problem with the settings.

Your tree assets are made with 3D Max.

This happens when the axes are not converted when exporting.

Draw a tree model.

In the hierarchy tab, click Create Tree to create a tree model and set up your own tree model.

Since the new project has texture elements that do not have trees and grass, they can be imported in the Unity3D Standard Library in the same way as described in the previous chapter. Open Unity3D, right-click in the Project tab bar, Import Package Tree Creator, and import the standard tree asset model into the project.

Click on Edit Textures and a drop-down list will appear.

add tree to add a model of the tree.

edit tree tree.

remove tree.

Inside the red box are some of the key important parameters for setting the tree.

brush size : The number of trees added to the brush at one time, the larger the value, the smaller the decrease, the value range is 0 to 100.

tree density: the percentage between trees, you need to modify this value when you put a tree in the middle of a tree, and the value ranges from 0 to 100.

color variation: the range of color differences between trees, with values ranging from 0 to 1.
