2k followers on Instagram! Thanks again to everyone who enjoys these experiments and animations, and thanks to the amazing artists on Instagram who have provided inspiration every day. You all are the best.
Thanks to the awesome Vellum intros from Entagma, I got a setup working to emit Houdini grain objects every few frames. This “sticky texture” technique is something I saw originally in the Processing community years ago, and then in 3D on GreyscaleGorilla with rigid bodies. The setup works by saving the simulation out to a sequence, UV-ing the last frame, then applying those UVs to all the other frames in the sequence. That way when played back again, it “settles” and the textures line up. I’ll clean up and post a .hip file in the next few days.
