Hi, Im making a farming simulator. And ive reached a stage where i have to Destroy or harvest crops. The problem that i am facing is that there are a lot of objects(meshes of the crops) in my scene. Because obviously a lot of crops make a field. Adding these meshes to my scene increases my Drawcalls to about 1.5K which is alot. Now i have tried to combine these meshes into a single mesh and i have succeeded so far. But In that case I Only have one mesh collider attached to the combined mesh. Which destroys the whole mesh when the mesh collider of my harvester collides with the mesh of the combined mesh. I donot want this. I want to destroy only those crops which collide with my harvester. Is there a work around? What should i do? Any help will be Appreciated!!
This is what static and dynamic batching is about. It tries to combine the meshes.
If you are building the game for PC and modern Android (GLES 3.0+), you can also use GPU instancing. It will be able to draw the same meshes efficiently. For it to work, the meshes have to be not batched, have same mesh and materials. Shader also has to support it, the standard one seems to work.
Disable dynamic batching and in profiler, open frame debugger, all the grass should have instanced mark.
Try to have the same material on every object.
