This Turkey flag and pole is a native Cinema 4D format. The Cinema 4D file is setup with SDS on a low resolution cage model. It is also setup with textures, materials, light and an HDRI sky object. You just need to load an HDRI image to the empty HDRI material balls luminance channel.

The FBX and OBJ's come in a lower polygon resolution and in high resolution formats. The materials will need tweaking to match the look of the preview images.
