My visits to Waterfire in Providence makes me think that these...

You can easily make these yourself, you know.
1. On a bare piece of ground, open the building editor and plunk down any gridded part. MUST be gridded.. It's best to use a flat roof tile or the 1m wooden gridded column.
2. While still editing this "building", click on the Scenery tab at the bottom and select either the Campfire or one of the flat square flame effects. Or a tiki torch, or any other source of flame. Add this on top of the gridded building part created in step 1.
3. With the flaming part highlighted, hit X to enter Advanced Move. Move the flaming part up into the air like 8m above the initial gridded building piece.
4. Save this all as a blueprint, then delete the original.
5. Dig your hole and fill it with water.
6. Open My Blueprints and select the saved floating fire pit. Place it somewhere in the pond you just made.
7. Enter edit mode on this "building" you just placed, then select the flaming part. Hit X to enter advanced move and adjust its altitude so it's even with the water's surface.
8. If you want more than 1 flaming thing, now's your chance. With the flaming part highlighted, select "Duplicate and Advanced Move". The movement arrows are now on a copy of the original flaming piece that's co-located with it. Move the duplicate to the desired position. When you click on the checkmark in the center of the Advanced Move interface, it will create another co-located duplicate. Move it and repeat until you have as many as you want. Then hit ESC to end the duplication process.
This this way, you end up with 1 "building" consisting of the single gridded part on the bottom of the pond, plus however many floating fire pits you want on the water's surface.
LoL so you would rather wait for a new update rather then just make it yourself? Thats kind of the way PC works, everything requires assembly. Theres so many scenery pieces people have requested this is just one of an infinite number of possibilities, and the reason why UGC will be so important. Either way you'll have to either wait or make due with what you got
