Unity's terrain system in mobile games because of the efficiency of the basic inability to use, only by t4m this terrain plug-in to optimize the production. Here is an overview of the use of processes and methods.
First, u3d the terrain and textures you want with your own terrain system. The stickers can be brushed around a bit. To be re-brushed later.
Export the terrain as an obj file with the export script Exportterrain.js and import 3DMAX, add Optimizer optimization commands to the model, and optimize the model. Then give the terrain a flat print of the UV. Export terrain to FBX format.
This is the number of triangle polygons that optimize the front terrain. The difference is very large.
Import the exported FBX file into unity, select the terrain, and open the T4m edit window under Windows. Click Process to successfully convert to a terrain with t4m to brush textures.
Follow the steps to add a surface map, and then swipe underneath the painter. The following tiling can adjust the Uvs for each layer of the map:
OK, that's easy. Here's a look at the comparison before and after the optimization. The effect basically changed little.
Look at the grid again.
end!
