One of the things I’ve been interested in simplifying, are the creation of boids systems. I’ve tried a couple of times to do it but I get lost in more complex trig (at least for me). I didn’t notice until last night that there were some Stoke tutorials posted here. http://www.thinkboxsoftware.com/Stoke/
The second I saw the velocity field wrapping around geo I was excited because I knew you could use that for object avoidance. I spent about an hour trying to use the field as a Stoke Follow in pflow, but then I remembered you could use the field as a standard force too! That made things soooo much simpler and more graceful. What’s neat too is that if you cache out the flow and you have particle colliding - I already know a solution that I’ve used before: Using a standard Magma flow you can have a distance threshold of 0 so that if it collides with any geo, it will move along the surface normal and then continue on it’s vector.
I only had time to post this screenshot, but I’m going to try and do a more involved test when I get more time. I’m all about simplifying
