  1. Hi people, I'm wanting to drop and object as an RBD sim, but have it finish in a specific xyz position and orientation. Basically, I want to drop a bunch of letters and have them form a word. At the moment, they land as I expected they would, but I was wondering if I could 'nudge' them to land in the right place? The realism of the sim isn't too important, but it would be difficult to get the feeling of them falling, if I tried to animate the letters by hand from start to finish. Can I cache the sim and add a value to it, over time, so it ends where I want it to? Can I run the sim and add to the XYZ co-ords as it's running? I could, of course, sim it in Maya or 3ds Max... convert it to keyframes... blend in a final rest pose... and import the Alembic, but I wanted to know if I could do the whole thing in Houdini before reverting to a method I actually know? Thanks

  7. hey all! Imagine you have a whole bunch of stuff, add an exploded view node, animate the scale and then you want to export that animation to unity. So far I tried using filmbox fbx with but the animation is missing in unity but shows up maya. I also tried using rbd to fbx from the game tools and packing everything to rbd before but the model aswell as the animation break in that case. what is the correct / standard way to export this?
  8. Hello! Is there a way to Animate Division Size parameter of a Smoke Object in Houdini Pyro? I tried keyframe it without success. Let's say I want 0.03 at the beginning of the shot and then slowly reduce the division size as the camera flyes away? What is the best approach of achieving this? Thank you guys

  12. What I'm looking for is an object to follow an elliptical curve, accelerating near the perigee and decelerating near the apogee. Theoretically I could wrestle with magnet forces and do a sim for this, but I feel that (1) that'd be unnecessarily complicated, and (2) that this is going to be a collider for another sim, and that might muck it up. I've tried follow path and using primuv, but I have not been able to find a way to accelerate and decelerate them as they follow the curve. I've tried something, attached, that is MOSTLY working. I get velocities from the tangent normals of the orbit curve, and a velocity multiplier based on the min and max x positions along the curve, so at the perigee the velocity multiplier is 1 (or whatever), and at the apogee it's 0.1. Using a solver SOP, each frame I transfer the curvevel attribute to the ball orbiting object at its current location, and then use @P += @curvevel. This actually works for the most part, except the orbiting object keeps going further and further out, creating a spiral orbit. Furthermore, even though I have a wrangle setting its initial position to be at point 0 of the path curve, starts farther away.(Also, I will need to figure out a way to orient it so it's always looking forward, but that will be easy enough, methinks.) I assume I'm missing something obvious within the solver SOP. This might be easy and dumb, so thanks for any help. (Also, if there's just a way better way to do this, I'm open to suggestions!) orbit_setup.hiplc

  14. Cloth wrapping animation

    So, I have a task to wrap rubber flexible mat around object. It is 1x1 meter electric insulation, and i need animation than shows how to wrap mat step by step using hands. I'm very new in Houdini, and not have experience in vex or other scripting, i'm trying to use only nodes. I came to next decision: I'm using vellum cloth as base, and some spheres in places where i grab cloth to move and drag. This spheres have vellum constraint "attach to geometry" with my cloth. And then i animate sphere moves, and simulate vellum. My problem is next - i don't need move all spheres all time, and in some moments i moving its manually, trying to simulate cloth real falling by gravity. So, how you can expect - it's weird. Does any way to detach and attach constraint attach to geometry not only at start frame, but through all my animaton time?
  15. Divider animation

    Hey people, I saw this free plugin for c4D https://www.behance.net/gallery/89028573/DIVIDER-FREE-C4D-FRAGMENTATION-PLUGIN It's pretty cool and this guy did a great set of animations with it. My question is... Anything ne have an idea of how to implement a similar system in Houdini... I would love to play with it. Thanks. Andy

  17. I manage to find a realistic way to position a train properly on a track. (see file attached) Wagon cannot simply be copied on an animated point on a curve as the centre is offset-ed in turns realistically. A path deformer is out of the question because of the deforming geometry This is my solution. 1) I created a 2 point line for each wagon 2) I path deformed the result 3) created a single point for each of those deformed line to copy each wagon onto, with proper vector for the wagon alignement I feel it is very complicated and i am curious for a better solution. If anyone interested to give his input. train_realistic_track.hip
  18. Hello! I have this two models, one of them is an animated mixamo fbx of a character doing a spin-attack with a sword, and the other is a katana, the mixamo model doesn't have the sword, just the hand open like holding something. I isolated some points on the hand, got the centroid and created a point there, subtracted the position of two points in the palm and the transfered that vector as a normal to the central points where the sword will be, so its aligned to the hand, kind of. This worked for the first frame of the animation but get it comes to the spin the sowrd just keeps the same angle as in the first frame, the long of the sword is correctly oriented but the blade-side of the sword doesn't follow correctly the orientation of the hand. I'm still learning houdini and I for sure missing something and I don't know how to really look up for this anywhere else. Thanks. Here are some snaps: https://gyazo.com/f6dac5288ed223ac63a6ccea8b69fce5 https://gyazo.com/018df6bf2b990d3a9cd2cb8f2b0aff6b https://gyazo.com/0e6803c89574a2899cc7c4ecf005e8fa https://gyazo.com/1f886158016b065d9fca1400ffa4e380
  19. Hair Guide Transfer Issues

    Hey guys, I'm still fairly new to Houdini and I am trying to make a hair sim for a character on a short film I'm on. I have created my groom on a static mesh of the character and I want to transfer it to the animated mesh. I've imported an alembic cache from Maya, matched topologies with the static mesh, cached that matched mesh out, then brought it back in. I want to transfer the guides to this newly cached mesh, but when I use the guide transfer node, it creates multiple instances of my groom and scatters them around the space. I have also tried the vellum constraint option "attach to geometry" with only the root points selected, hoping the rest of the curves will follow but only the root points moved. Not only that, but they didn't spread across the mesh to their correct position. At this point, I'm not really sure what to do anymore. Any recommendations are welcome. I can attach the file too but I'm not sure if that would be much use since you would need the cache files too.
  20. I am trying to animate the rotation and position of transform node inside of an object. The keys seem to be forced to linear interpolation and I can't seem to convert them to anything else or modify the handles. I can see and move the handles but they don't change the curvature of the animation spline.
  21. Hi all! I have very long string of different, fairly poly heavy, CAD models put together. I'm animating these along a curved path, and the path itself also has some animation on it. I've been using the Path Deform SOP from the GameDev toolkit, and it works, but is dreadly slow on such a long and complex object and millions of points. And dealing with adjusting from client feedback, it makes it really hard to iterate on. So.. just looking to see if anyone could think of some optimizations techniques? I was thinking to use a low poly string. Animate and adjust, having some workable feedback, then transfer that animation on to the high poly string - but not sure how to approach that. Edit: I can of course replace the low poly with the high poly at the end, but it takes 4-5 minutes to calculate per frame. So just looking to see if there are other approaches. Point deform is close. It really fast transfers the high poly to the low poly mesh, but it deforms the source too much besides just following the spline. Still tweaking on this to see if I can get acceptable results. Any tips and suggestions would be greatly appreciated. Thanks!
  22. Hi, magicians! I already broke my mind trying to solve a simple problem) I created a point infection system and for every point I copy the geometry so I want geometry to grow from every new point. It seems that I need to associate the pscale attribute with the time attribute, but the pscale grows constantly in time which is logical. In addition, all new points grow from the existing @Time value associated with the @pscale. So how can I make growing @pscale in every new point from zero and stop after few frame/time with little random pscale? Or I think it’s wrong and I need to change the approach. Maybe try to animate the uniformscale in the geometry itself through some expression? I would be grateful for any advice
  23. How to shatter animated objects?

    Hey there guys! I was playing with a little Mixamo animation I downloaded. The animation consists of a dude falling down, I want it to fracture when he falls down and have a little control over that. So I tried to import the Mixamo, convert it, file cache it and apply a simple RBD glued sim. I changed the source to be a deforming active object so the shattering applies to the animated mesh. I tried to play with the glue parameters to have more control over when I want the guy to shatter but the only results I'm getting are crashes, so I obviously think I'm missing something. Here I attach the file and the fbx. Any ideas? Thank you! Trapo. shattering_animation_01.hipncFalling Down (1).fbx
  24. Recent work from Chinese animated feature 哪吒 (NeZha), I was responsible for creating and rendering of the water effects using Houdini flip to build a guided system for water and render in Mantra, final compositing done in Nuke.
  25. I'm using a POP VOP to add some noise to my vellum geometry, but it keeps sticking to other geometry when it collides. I assume this is because the geometry is displacing before Vellum can catch it, and by the time it does it's already intersecting. How can I make this work correctly?
