LogInMade with Geometry Nodes for a larger city simulation project.
Sometimes, even work-in-progress R&D projects can outshine gameplay mechanics introduced by AAA developers in their big-budget titles, and this project, showcased recently by Reddit user gallifreyfalls55, is a perfect example.
Created as part of a larger city generator, the project features an impressive procedural crowd simulation with collision avoidance and seamless looping, allowing pedestrian NPCs to walk in straight lines on sidewalks without clipping through each other. This setup is powered by Blender's Geometry Nodes and utilizes character models from Anima and animations from Mixamo.
What's more, the system runs in real-time, and for the showcase demo, the creator baked the Simulation Nodes and rendered the output, with the simulation playing in real-time within Blender's viewport. Regarding performance, the author noted that it depends on the simulation's scale and the hardware being used. "Calculation time on the Geometry Nodes with 15 people (as per this animation) was 3.2 ms, and the majority of that is coming from the visualization lines," gallifreyfalls55 noted.
