Tree of Prosperity mod: Pixie and Firefly Light Show Spawn Fix

Now your sims’ gardens will be busier than ever with Pixie and Firefles coming to visit in the evenings. This mod is available at ModThesims.

Note: You MUST have the Tree of Prosperity from the Sims 3 Store in order for this mod to work. The Tree of Prosperity is also available as part of the  Lunar Lakes world. This mod will not add the Tree of Prosperity to your game.

This is an object script mod which removes the requirement for a Wishing Well to present on the lot in order for the Pixie and Firefly Light Show to spawn.


16 May 2012 – Update for Store Content Patch V1.1

28 March 2012 – Minor change to assembly information and assembly name. No changes to the script were made. Although I recommend re-downloading, it is not necessary.

9 March 2012 –  Fixed the ITUN resources so that your sims can autonomously Imbue Tree and Pick Fruit. If you wish for your sims to do these interactions autonomously, please download You must use both this package and the NonaMena_TreeOfProsperity_LightShow(-DECRAPPED) package. If you don’t care for those actions to be autonomous, you don’t have to download the ITUNs.

Also: We will see a Wishing Well in the future.


8 March 2012 – Updated the script and tuning file so that the tuning actually worksPlease re-download if you want to tune the Tree. You do not need to re-download if you don’t want to change the default tuning of the Tree. This tuning file will not work unless you also use the Light Show Fix mod. If you want to tune an unmodded tree, use Black Zekrom’s tuning file.


  • Again, this requires the Tree of Prosperity from the Sims 3 Store to be installed in your game, or it will do absolutely nothing
  • The Tree of Prosperity is available separately or also as part of the Lunar Lakes world.
  • No other Expansion or Stuff Packs are required for this mod, ONLY the store world.
  • This mod was built with patch 1.31, but it should be compatible with any patch level that can run Lunar Lakes.


  • This mod will conflict with any other mod that alters the OBJK resource (Instance 0x00000000000F5449) for Tree of Prosperity. I do not currently know of any other mods that do this.
  • If you want to increase or decrease the chance of seeing a light show, you will need to edit the XML Tuning for the Tree of Prosperity. To do this, you must use the tuning file I have provided. You cannot tune the Tree with any other XML tuning file when you have this mod installed
  • This mod will not conflict with Black Zekrom’s tuning mod, nor with Jamie’s tuning mod from iPlaySims. However, using those mods alongside this mod will be a waste of space, as those mods will not have any effect on the Tree when this mod is installed.
  • This mod has no known conflicts.

The defaults for the following can be changed in the XML tuning file provided. Please see the XML for more details. How to Edit XML tuning files (NRaas industries tutorial).

Tag Description Default
kFireflyPixieStartTime Hour of the day that the Firefly/Pixie VFX begin 23 *
kFireflyPixieDuration Duration in hours of Firefly/Pixie VFX 4
kChanceOfFireflyShow Chance of a Firefly show appearing at night 20 (%)
kChanceOfPixieShow Chance of a Pixie show appearing at night 25 (%)
kFireflyFunBump Fun bonus given to Sims near tree during Firefly show 30
kFireflyFunBumpPlus Extra Firefly Fun bonus added to/removed from Sims with certain traits 15
kPixieFunBump Fun bonus given to Sims near tree during Pixie show 40
kPixieFunBumpPlus Extra Pixie Fun bonus added to/removed from Sims with certain traits 5

* Pixies and Fireflies flourish in the night time and are not easily visible in the day time. Make sure you set your show at night so you can properly appreciate them.

This is great! But why, exactly, doesn’t it work without this mod?
The original coding for the Tree of Prosperity checks two conditions before it spawns a light show. First it checks if the time matches the tuning for kFireflyPixieStartTime, then it checks if there is an objects on the lot, called WishingWell. If either of those are false, the show doesn’t start. However, currently, there is no WishingWell available for the Sims 3. Maybe this is a future premium content item, or maybe EA had planned on making it but decided against it.

What if EA releases a Wishing Well?
If and when EA releases the Wishing Well that is required to spawn the light show from the Tree of Prosperity, I will revisit this mod and see if it’s still necessary or needs changes.

Your screenshots are awful!
I’m sorry, but the pixies and fireflies are shy and not very photogenic.

Shimrod, Buzzler and twallan for their brilliant brains and friendly, helpful natures.

I must point out that I deserve absolutely zero credit for this mod. The idea of this mod would have entirely died if Shimrod had not pointed out to me that the Pixie and Firefly shows could be triggered with a Debug Enabler mod when I was assuming that EA must have ditched the project. When I finally decided to look at the script myself and find out why the Pixies and Fireflies wouldn’t spawn on their own, I would not have been able to compile the script without Buzzler’s very kind advice.

Actually, I didn’t really do much at all to make this work. All I did was remove a single piece of code which checked for the presence of a WishingWell on the lot before spawning the light show.

  2. As you probably already know the new town based on Las Vegas, will be available soon. It has a wishing well, and if you have the tree of prosperity in this town too, you get the pixie show without any mods.

    • Yep, Brandon, thanks for leaving a comment 🙂 I will probably revisit this mod after the town is released. Or I might just leave it be and label it obsolete. I haven’t really made up my mind yet.

  3. Hi Nona, hope u’re fine and your back is feeling better!
    I have a question: Is your mod compatible with the wishing well? Or shall I delete it?
    Thank you. Have a nice weekend! =)
