Modeled with Autodesk Maya 2020 using polygons.

With materials and textures.

All the objects parent and group correctly.

Reduce o eliminated grass if you want much less polygons count.

The file called ' render ' is to render like the first imatge with Arnold Render. For best results add a render occlusion on it.

Formats mb,, fbx, Blender, Obj and 3dmax.

These formats with basic materials and textures.

Thanks for your support.
