  1. Hi guys, Just want to showcase our work in progress and ask everybody's opinion. The demo is HERE. In short, were able to transfer Houdini vertex animation to a Web Browser. To accomplish that we used Houdini texture cache tools, 3js library, and tinyexr loader which was compiled to JavaScript. We are exited about the result and looking for a project to apply it.

  2. dr strange time slices effect

    hi all so heres one for you - we all love the kaleidoscopic mirror dimension.. and the cool portals and wotnot in Dr strange... BUT can anyone suggest any ideas for how to tackle this really cool but very quick effect in houdini? At 28 seconds we see Kaecilius sort of reverse backwards into various slices as he does so.. I think its a really cool effect and one i would like to try suss out for a cg character. My thoughts are to bring alembic cg dude in, run him through a vdb and back to polys, then use a copy sop and a grid to create slices in the mesh... much like this cool tut... but how do i get that frame offset effect where you can see the slices are running at different frame times ? dunno if i'm explaining it well but does anyone have any ideas? Its something i'd love to crack! ta Ant
  3. Hello,I'm attempting to create the slitscan/timeshift effect. I'm creating a vector array in a for loop, each loop has an attrib from map and a wrangle that appends Cd to a vector array. It works when the attrib from map is always reading from the same file. When I change the attrib from map file read expression to anything that has to do with $F or the meta nodes iteration Houdini crashes. I have a test scene that has documentation and even nodes setup to create test frames to work with.If it is a matter of the way that multiple files cannot be read at once please let me know. If someone knows of a better way to read from multiple files at once and/or achieve this effect please let me know. I'm aware that after effects has this effect and uses gradients to determine which frame to look up color from. While that method is great, I'd like to be able to write the gradients/lookups in vex to achieve results. Any help greatly appreciated. -T concept_025_slitScan_v001.hiplc
  4. Hey, I'm here with an "old" question, I know it's been discussed/explained already, but I'm still struggling with getting rendering time estimations :/ I've found some info, but it's more about OSX and Linux, and it seems to be different with windows. First, I don't know how to bring up the console (don't laugh please). All I could find was to set mantra verbose level to at least 1, which is already at one by default, and that it could also be seen in the render scheduler. So I launch the render scheduler, set it to not clear completed tasks, but when I hit render to disk (rendering a sequence) the render scheduler isn't showing any info. It's only when the animation is all rendered that the scheduler display a list of task, when it's too late. Since I don't know how to bring up the console, I'm in the dark about some needed render time estimations :/ How do you guys get those info ? I'd love to at least see the total render time estimation somehow. Thanks !
  5. Time Shift Node

    I have a scene where I want to put few Dust Explosions, but Of course they would look better if they would start on diferent times. So I`m using DOP i/o and then TimeShift node just frame number minus random frames. ($F-24 for example) Problem is that on frame number 10 it is 10-24=-14 and the mantra gives me error and doesn`t render anything. What would be the best way to do it then? Thank you
  6. Adding time to cloudnoise

    Hi everyone ! I'm doing some clouds with CloudFx and I wanted to animate them a bit. For the moment I have tried to set an expression to the offset of the cloudnoise but I'm not very happy with it... The patern is sliding on the cloud which is not convincing... I am pretty new to the world of VOP but I have seen that inside the cloudnoise stands a Volume VOP (cloudnoise), I know that I have to add time inside of it, but does not understant how... Is it possible to have some help ? Thanks ! ValentinD
  7. Hi,guys, I am trying to build a digital asset here,It's a asset inside shader,I mean it's at vex builder level. And now I want there to be some parameter which link to a rotation of an object level camera. Because the rotation keep changing,so I must like write a expression for the parameter of the DA. And here is the problem,it seems that I can't write expression at vex builder level,it does not update. I know I can promote parameter to shader level,but I do want to keep it at my digital asset which is at vex builder level. So,how can I get that changing data and make it work for my digital asset? I did some test,maybe someone can check my test scene(houdini14) and help. Thank you guys. Peng.
  8. Hi everyone I#m fairly new to Houdini, and i bet there is probably a easier way to solve my problem. So what I try to achieve: I have a curve with 10 pointsl. Now I would like to copy individual Spheres onto the points of this curve - but not all at once! I have a frame range from 160 to 180 on which I would like this effect to happen. Every 2 frames (x variable number) I would like to have one Sphere being copied onto the next point of the curve. (if $F%2, 1, 0) -> copy ..basically BUT the previous one should not dissapear! Nor do I want any others to appear. In the end after a number of frames all 10 points have 1 sphere copied onto them. I tried it with the Carve SOP but the point numbers vary and the "carve end" creates an additional 11th moving point. So this is not the sollution I am looking for. I also tried a "delete" SOP with an expression, but all I managed was the points appearing and dissapearing again. And I can#t think of any way to iterate over the curve points in a way that excludes the already copied ones. Please help! I am kinda stuck. Cheers
