I didn't realize those where your grass blades meshes.

I forgot to comment about your retopolgy comment but I know a lot make there stuff in zBrush and then retopologize it Zremesher it.

but I'm not modeling the tank to be retopologize.the red mesh is the final mesh.

 

I'm still working on the tank Treads ,making them more 3 dimensional in stead of so 2 dimensional.

If I make it in the just none rounded cube style "blue mesh" polycount 75,000.but I don't like the look.

If I bevel the edges "red mesh" polycount 150,000 and you can SubD the mesh.
So I'm making the tank with bevels.

I could make a 500 to 5000 polycount tank and texture the low polycount tank with the 150,000 polycount tank renders and use them as textures.

500 polycount treads wouldn't role

5000,150,000 polycount treads could role if the app can make it so.
