OpenSim creators Dirty Helga and Spax Orion released a free NPC management station to the community last week, giving world builders a streamlined way to create, preview, and manage non-player characters from a single in-world object, according to a post by Spax Orion on OpenSimWorld.
The IMAGE-NPC Machine is a streamlined NPC management station for OpenSim 0.9.x that lets creators snapshot avatars’ appearances into notecards, preview NPCs from a library, cycle animations for posing, and manage all NPCs from one linkset.
“I recently retired and open-sourced everything SimGEAR,” Spax Orion, sysop of Ozone Miniverse, told Hypergrid Business by email. “I made a free game engine for OpenSim called IMAGE.”
Spax Orion said the project grew out of frustration with the state of OpenSim game tools.
“KONK is dead and the other game engines out there are lacking,” he said. “I decided to do something about that.”
“I am dedicating my personal time to code amazing things for OpenSim,” he added.
For OpenSim world builders — who have long relied on fragmented, multi-script NPC tools — a single consolidated station is a practical upgrade, particularly for role-play regions, stores, and educational environments that depend on populated, realistic-looking spaces.
Part of a larger framework
The NPC Machine is the latest component of the IMAGE framework — short for Image Matrix Action Game Engine — a broader project that Dirty Helga and Spax Orion have been developing and releasing to the community over the past several months, according to Spax Orion’s blog.
SimGEAR was Spax Orion’s previous commercial content brand, under which he sold NPC furniture and scripted tools on the Kitely Market under the name Spax Zorin. The tools are now free and open source.
The original test platform for IMAGE is a game called Grug Assault, a drop-in game system where NPC monsters invade a region and players fight them off. The NPC Machine spun out of that work as a standalone tool for creators who need to manage NPC appearances without the full game framework.
The IMAGE framework also includes iMinstrel, a dynamic NPC command-and-control system for storytellers that can be connected to a local AI model for conversational NPC behavior, Spax Orion said on his blog.
Public debut at HG Safari
The IMAGE framework had its official launch on March 11, when HG Safari visited Spax Orion’s Ozone Miniverse grid for what the visitors believed was a stress test — and turned out to be a surprise release party, according to a writeup on the HG Safari blog.
“I have a lot of free time on my hands and if anyone else has free time, and wants to learn or even better, contribute to the IMAGE project, lets talk,” Spax Orion said during the event. “I find coding chaos to be quite therapeutic.”
What it replaces
“This replaces our old four-script system with a single root-prim engine using pure OSSL — no permission issues or orphan NPCs,” Spax Orion said in the OpenSimWorld post. “It’s owner-only and prevents unauthorized sitting.”
The orphan NPC problem — where scripts lost track of NPCs they had created and left them stranded in regions — was a persistent nuisance with older tools. The switch to OSSL functions eliminates the permission handshakes that caused the issue, according to the README included with the tool.
Spax Orion noted that the earlier ActiveNPC framework by developer Satyr Aeon, which he helped test, remains a solid tool. The new IMAGE NPC system is not a replacement for ActiveNPC, he said, but a separate approach.
Quick setup
Setup takes about 30 seconds, Spax Orion said in the post. Users rez four cubes, link them, insert the assembler script, and touch once. The machine reshapes the linkset, then self-deletes. Users then add a few standing animations and the IMAGE-NPC-Machine.lsl script to start using it.
“I have had this tool for several years and I have been meaning to share it,” Spax Orion said in the post comments.
Community response
The post drew 20 likes within a day of publication. Several community members noted they had been using older workarounds.
“I had been using the zombie creation tool found in Lani mall to make NPC appearance notecards when needed,” MrSnoodle said in the comments. “Your tool will be the better choice, so thank you.”

The tool is released under a CC BY-NC license — free to use and share, but not to sell. It is available in the OpenSimWorld script library. For OpenSim NPC documentation, see the official OpenSimulator wiki.
Visitors can see the IMAGE framework in action at Spax Orion’s Ozone Miniverse grid, which is accessible via the hypergrid at xoaox.de:7000:Atrius.
