Very well explained and yet surprisingly terse!
Thank you very much.
This is great, makes me want to mess around in blender more often
Just do it! :D
The only part lacking is the light fading on and off. It does but not individually. The entire group still is fading on and off together and that is extremely unrealistic. What should happen is each instance should have it's own fade time. Or a random time created at the time of instanciating each one. I haven't figured it out yet but a sine wave won't work. It's too cyclic. It needs to be on for about 1 to 2 seconds, off for a random time of 3 to 4 seconds for EACH instance. that would give you say X percentage on at any given time instead of what you have here. I haven't figured that out yet. Perhaps a noise texture is more random and could drive the off and on times? anyway, thanks for the vid!!!!
Yes, now with Simulation Nodes I would build it differently anyway.
You could just give every instance it's own little sine graph with just some offset and a bit randomization.
how to set the firefly move speed?
You can just increase the output of the Math Node which I set at 0:57.
That value is the base for the rotation speed, just increase the small mulitplier.
Thanks so much again!
Not sure if you check your old videos but if you do - When I try to plug "Firefly Amount" into the mesh line my points vanish! Otherwise, it's all fine. Any ideas? Also, thanks so much for making this video and putting it out there! I'm learning and it's incredibly helpful to have videos like this to assist. :D (Oh, also - any idea on how to slow them down?)
When you look closely, they disappear too in the video. I just increase the value back again in the slider on the right. When you plug something from the input to a node it will reset to it's default value (0 in this case).
To slow them down, you have to decrease the rotation change, you do that with the bottom number of the multiply node with the violet #frame in it. The bottom number, which is low is something like a factor for the rotation speed. ( 0:58 )
@@PointCloud thanks so much for the reply! I really appreciate you taking the time to help!
is there a way to get the particles to avoid each other?
I'd say not really with this method, because it is just randomized position and movement.
Maybe you can just find a seed where it looks alright.
@@PointCloud ah cool cool
i was actually wanting to build a system with a bunch of fish lazily swimming in a pond so avoiding each other. My geometry nodes abilities arent quite there though ha ha. Thank you though!
@@jamesrowsell9346 Maybe you can use boids for that instead of geometry nodes. These are like particles with a more or less controlled behaviour.
