  1. Hi, I'm new to Houdini and I'm trying to create a dandelion blowing in the wind type of effect. So far I have the constrained the dandelion seed geometry on a sphere and have created a pop network so the dandelion seeds fly off. This is fine however I'm trying to find a way to make the particles stick to the surface and only fly off the surface when the seeds reach a certain angle ( say 20 degrees ) from the normal. I've been looking at this tutorial of how to create this effect in Maya but I'm finding it difficult to translate this into Houdini. I think you're supposed to use VOP's to create the same effect but I'm just a bit puzzled of how to do so cause I haven't used VOPs before :/. Maya Tutorial I've attached my file below. Thanks in advance! DandelionGeo.hipnc
  2. Dandelion Wire Weighting

    Hi, I was wondering if anyone could help me with this. I'm creating a dandelion simulation where the geometry is attached to each wire and all the wires are being deformed. I'm having problems as the geometry spazzes out once the dandelion seeds come off the dandelion ball. Is the any way to fix the geometry right on to the wire so it doesn't deform because I think that's what the problem is. I'm kinda new to houdini, it's probably a silly error I can't see. Thanks in advance!
  3. Dandelion Wire Simulation

    Hey folks, I am trying to create a realistic dandelion simulation and beginning to bang my head against the wall/desk. I'd like to end up with this: I have attached my (rather tortured) scene attempt. My method is to bring all the sop geometry in as one big wire sim and affect gluetoanimation and kangular on the fluff/stem. There are 3 movements that I'm attempting to capture: 1. The twitching of the fluff 2. The bending of the stem while the prongs are still attached 3. The moving of the prong/fluff when they a re broken. I am achieving the first movement by affecting the wires with wind with random activation (otherwise the wires settle to still) but I don't want this wind to affect the prongs. Basically I'm all tangled up and if anyone has any ideas it would help me out a lot. Thanks all dandelion_Test.hip
