  1. FLIP - Hold tip of a snot?

    Hey guys, I'm working on this snot simulation and I need the top part of it to be "attached" to a nose. Any ideas on how to proceed? EDIT: Right now it's like this but I need to "constraint" it to a character. Thank's Alvaro Snot - v1-a.hipnc
  2. Hello, I'm looking for the best way to prevent an attribute from changing once it has reached a certain value. I'll have other benefits from this, but for now it's to control the "active" state of some points via an animated object. I'm setting a group of point with a bounding sphere grouping, then I wrangle i@active = 1 for that group. but, obviously, when a point is back out of the sphere, it's out of the group and gets a @active = 0 again. I'm wondering if it's doable in VEX (if active becomes 1 then never change again) or if there's other tricks to do that. here is a simple hip file where I move the points up when they are in group1, so for this exemple, I would like the point to never come back down if they get moved. Thank you! I've seen a way to do that in a particle tutorial, where the colours get changed and is then prevent from changing back when outside a box, but I just can't remember, and can't get my hand on that video again : / OD-F_keepattrib.hipnc
  3. Hello, I've been studying Houdini for a couple of months now, so forgive me, if this seems kind of stupid. I have a very simple scene of a ball destroying a plank of wood. I got the fracture, and and simulation running, but I was wondering on how to hold this wood in the vertical position. Basicaly, what I want to do is select the base of the fracture plank and just freeze that, still using the glue to keep everything together, so when the ball hits, everything breaks and just the bottom part stays in position. I got a box in the scene to show the range of what I want to select. Thank You. Fracture_Test.hipnc
