Can anyone help me to reduce Tris and Verts

as you can see i have a 4.5 tris and 5.1 verts.
and on scene. 12 bus, 1 building, 3 fence and 1 gas station,

so I delete the other buses, verts and tris are reduced to 600 and 600k

So I dont know what I do. can anyone help me ?

that is important :confused:

When you export the models from the software, there should be a setting to make the mesh have less tris.

Maybe you could tell me what software you are using?

Hope this helps!
