Modeled with Autodesk Maya 2022 using polygons.

With materials and textures.

All the objects parent and group correctly.

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

You need a medium/high powerful computer to move the scene.
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, and Obj.

These formats with basic materials and textures.

Thanks for your support.
