  1. Creating a node takes ages. What could be the problem that is making it so slow? It did this after the latest update (updated 15.5.632 to 15.5.674) Please note that we already tried to install versions as far back as 15.0 and until the latest version of 15.5. The problem keeps occurring even without virus scanners and windows defender being turned off. It also doesn't matter if it is installed on a SDD or on a HDD and all the drivers are up to date. Even if all the preferences have been deleted (in the documents directory) it stays the same and it also doesn't matter on which Houdini License server it's running: in Standalone mode or not. I'm running out of ideas to what the problem could be. If you know the solution or have an idea what it could be, let me know! Please ignore the audio in the example video below, it is in a noisy classroom with students discussing different nodes (not related to what you see, you can watch without audio)
  2. Hi, I am rendering with Arnold a scene which contains really small portion of frame. Maybe 5%. Rendering of this part is really quick as shaders are just flat colors without shading, GI, glossy etc... But rendering the rest of the frame - empty, or black area takes much more time. Is there a way to render only part of frame which contains geometry and maybe a little padding (for motion blur)? Because it would speed up my renders up to 10x times Thanks, Juraj
  3. Hi, if you could have a look at this hip, I bet I'm doing it wrong cause it's very slow. It's 2500 boxes (copysop + stamping) growing up. I scatter points on a painted grid, fuse points to avoid overlapping, attributeVOP to randomize and add a fadeout effect. I'd learn a lot if someone could point out the mistakes. Might not be mistakes, but maybe there's ways to optimize. I'm not comfortable with coding yet, so I couldn't wrangle this, but if I'm not mistaken, VOP is VEX, so I was expecting faster cooking. Could it be slow elsewhere ? the copysop? I checked "packed geo bedore copying" just to see... still slow. Or before the VOP? I unchecked "relax "iterations" in the scatter node to speed up the scattering, in case it was cooking it each frame, but no. OR the number of boxes is the pb and there's no way to optimize? I doubt that as I've got heavier scene running smoothly. if you have the time, I'd appreciate thanks, cyril. optimizeBOX.hipnc
  4. Hi, I have Houdini Indie, I am trying to simulate a cloth animation and am getting very, very slow results. I am doing a simple grid with 100 by 100 res fall into a smaller cube. On the default Finite Element Solver settings it is taking close to a minute per frame. If I increase the res of my mesh to 300 by 300 it gets close to 12 min per frame (I am running dual high end xeons, 256GB RAM, Quadro4200 and Tesla K40c). I am not even seeing good CPU utilization hovering between 9 and 12% I tried to disable substepping and setting the Max Iterations Linear Solve to 128 but it barely has any effect. Is this normal behavior or can I assume something is wrong?? Thanks,
  5. Hi, I've made a very simple scene to create the steam of a steam train, kind of cowboyish one for a little project. There is one scene where we need it to be in slow mo, like half speed. Beeing very new to houdini I would like to know if my setup is "correct/optimized" or if you have any tips to make it look better maybe, but more importantly what would be a good way to slow down the simulation, I've tested the dopnetwork time scale value but the results are not great with my scene. Thank you very much !
  6. Hello everyone, I am trying to create an effect for a project where particle is moving in a tube with constant speed. What I need is to particle gets slow down at crushed cross section (shown by red arrow in image ) and then move ahead at normal speed. Any pointers to achieve this will be helpful. I have attached a reference image to get better understanding. Thanks in advance.

  8. Hey Guys, I know this has been asked a few times, and I did some searching, but I'm still unclear on a few things. I need to retime a large RBD sim, with many objects. The time scale parm on the dop network doesn't seem to be much use (?), and I've tried messing around with using a dop import to fetch my sim, and send that into a timeshift sop, but then how do I go about caching everything out? Is there a better way to do this? with more control? less iterations? Thanks!
