Modding Your Pump Tank

In the end of March we released a Full Perm pump tank mod kit. While we don’t provide tutorials on how to mod, or create custom textures or things, and can’t support the work of others, I wanted to go over a few tips and tricks that might be helpful when doing a pump tank mod. The script interacts with the parts of the tank based on their names. This can be used to create similar effects in your tank mods and I will explain what the script does and examples of how it could be used below.


On the tank there is a red light when not pumping and a green light when it is pumping. These prims are named “red light” and “green light” Any prim named “red light” will show when not pumping but go transparent when pumping starts, the opposite is true for prims named “green light”

possible uses:

  • A lidded container that shows a copy of the lid hanging to the side while pumping but a lid on top when not.
  • An animated prim showing milk squirting into the tank that shows when pumping but is hidden when not.


The prim that changes to display the milk volume in the tank is named “milk gauge prim” The script changes the size of this prim on the Z axis to show filling milk. So any edits made to change the size of that prim on that access will be undone when the tank updates its contents. You can alter the “Slice” of this prim to cut back how large it can go.

possible uses:

  • large milk prim inside a transparent tank
  • made transparent and prim size read by script to change another feature to show milk fullness


The prim that is animated when pumping starts is called “bellows” if the script can’t find a prim labeled “bellows” it will grab another prim to animate, the bellows shape change is hard set in the script and so will resize itself back to original when pumping starts, and the script will only animate one “bellows” prim.

possible uses:

  • Replace bellows prim with one of your own making.
  • make transparent and have script read size changes to create another pumping effect.

So armed with these tid bits of information we want to see what you can do! We are having a Tank Mod-Off! What you need to do to participate is to take an picture or two of your custom pump tank and and upload it to our flickr group for the contest. The parts do not need to all be made by you, but it does need to be something that is not for sale AS a pump tank mod, So if you took a pre-made back back and made it into a pump tank that is fine.  Include avatar name and a link to a video if you want to show the tank in action. Five favorites will be picked from those submitted and featured in a blog post on June 3rd for voting. The winner of that will get a custom tank exclusively made for this contest from SuperNova Ind. and if I can get one I might have a custom tank mod to give away to one lucky voter in a random drawing so keep an eye out for that!
