A small version of my large octagonal garden bed that also holds benches and a fire pit. It is well-suited for large properties, such as a college campus or an estate. I've included the base mesh as well for you to add custom materials. This object is not game ready, but it is able to be converted.
Disclaimer: The download does NOT include the foliage you see in the preview image. This was just an example render to show you how it can be set up. Choice of plants is up to you.
