Obstacle Avoidance: Flow Fields
A quick and easy method for guiding particles / agents / things around obstacles, using Attribute Blur and Measurement SOPs.
Quick Question about the Measure Sop: my heat isn’t visible with the Measure Sop like yours. I even downloaded your Project File and have the same Issue. I’m currently using H17.5
Hi Ozzi,
you might wanna download H18 then 🙂
Cheers, Mo
Ozzi, with the Measure SOP selected press enter in the viewport. The Measure SOP has a dedicated visualization state. Works in 17.5 too.
Loved this Moritz. I added some noise via a point Vop in the solver: https://www.instagram.com/p/B6qdzF1h1q6/?igshid=18vh78jlgwm2c
Hui! Really neat pattern you’re getting out of it! Nice one.
Works really nicely as a pop wrangle inside a popnet so you can add things like pop interact and vary the drag for an organic flocking kinda thing.
My script isn’t working and the downloadable project file doesn’t work for me to compare with.
Hi James,
I just tested the scene file and it works for me in H18.5.535 – Are you getting any error message? Or rather: Which part specifically isn’t working for you?
Cheers, Mo
Im using H19.0.55 Any idea if measure sop has change? im not able to exclude the geometries from my flow field. Thanks for the tutorial btw 🙂
Hi Gus,
I have the feeling it’s connected to this: https://entagma.com/quicktip-new-grouping-behaviour-in-h19/

Hi Mo or anyone 🙂
How did you get objects in your video preview to follow the path and not to be deformed. I added sphere, connected it with CopyToPoints node to Scatter and then to solver. The animation works but my spheres got deformed. It would be great if you or anyone else can answer and help me. Thanks – NEB
I recently tried to use this technique to create guide curves to drive particles that move through a cityscape created with OSM data. However, it seems to fall apart when there are a lot of objects, in this case, buildings, for it to avoid, in which case the points seem to just want to go around everything. Any thoughts on how to control this with a denser cluster of objects so that they move more closely through dense areas. To be clear, it works when I just have a few buildings, or a single city block.
