  2. RenderMan IPR not working

    happybabywzy posted a topic in General Houdini Questions

    Hi guys,I ran into a problem after i installed RenderMan23 for Houdini18,click the IPR button on the shelf have no any reaction,is it a bug?

  6. Creating smooth curve from imported curve geometry

    acey195 replied to straaljager's topic in Modeling

    Hey, Welcome to Houdini! May I suggest using the convert SOP (converting it to third order NURBS) you may also find it useful to: use the facet SOP using the "Remove Inline Points" toggle and then play with the distance to remove some "oversampling" use the fuse SOP to merge nearby points in corners (to avoid having sharp corners using convert) resample with a large value for "Maximum Segment Length" to reduce the noise in your samples Or alternatively, you can also keep your geometry at polygons with the resample SOP, setting the "Treat Polygon As" dropdown to "Subdivision Curves"

  12. Use Ordered Menu to Change Parameters in Tool

    Drughi replied to grafikzeug's topic in Tools (HDA's etc.)

    If you want to keep it a subnet. This is the way to go. DropdownToChangeValues_fix.hipnc In the sliders working geo
  13. Thanks. One final step: how to make the size of a box match the measured x,y,z of a bound, not copy pasting values, but linked? And position. So the idea is to create a box that perfectly matches the size and position of a bound node.

  14. Use Ordered Menu to Change Parameters in Tool

    Drughi replied to grafikzeug's topic in Tools (HDA's etc.)

    You will need a python script for this to work. Do you want to make a hda or keep it a subnet?
  15. Hi! I want to share with you a little script I did which I find quite useful. It allows you to convert for example alembic cameras to regular houdini cameras. Additionally it can scale cameras correctly and in general bake cameras. You will find the script here: MyWebsite

    flo replied to Yao Zhuoxing's topic in Hardware

    I'm not sure this will help, but you could try an older driver for your intel graphics (version 25.20.100.6583, A06 seems to work for XPS 15, not sure what version that would be for your XPS 13 though)... Let me know how it turns out, cheers

  22. Ola @flcc here you gonna find I think some fun stuff ...file to learn triggers and how ? you know Vex so I think its easily manageable to convert attributs . plus some things to Know if not Ready trig.hipnc

  23. Solaris camera

    cubiccube replied to kiryha's topic in Lighting & Rendering

    There are some good example hip files inside of the support materials for Solaris in the h18 docs that might answer some of your questions. The download link is buried in here: https://www.sidefx.com/docs/houdini/solaris/tutorials.html
  24. Thanks Tomas.

  25. (displacement) splitted edges

    jimeng20 replied to oooskar's topic in General Houdini Questions

    Hi there, Have you try fuse sop? Also are those two individual geometry?
  26. Hi there, Also I think there are some info that I found can help you to better understand quaternions/orient and matrices. http://www.tokeru.com/cgwiki/index.php?title=JoyOfVex17 Hope this would help.

  27. Create Realistic Clouds in Houdini - VFX BREAKDOWN

    Sarkstir replied to VFX Grace's topic in Finished Work

    This looks great. I've been working with making some clouds and wanted to do something similar. How did you work in the gas microsolvers on your clouds to achieve that evolving effect?
  28. if you don't plan to cache the substeps and there is no other solver than FLIP then by setting Flip Solver substeps to 2,4 for example you should get comparable results to DopNet substeps 2 and flip substeps 1,2 etc... the most important is that your collision geo is accessible and correct at each substep

  31. For better collisions of fluid with geometry with FLIP, should you add your substeps on the FLIP Solver, or on the parent DOP Network?

  33. Only mesh flip particles that are closest together?

    jimeng20 replied to JFWfilms's topic in Effects

    Hi there, I'm sure there are a lot of different ways to do that, I will probably use point cloud to found out the how many points in the searching area. For example int pts[] = pcfind(0, "P", @P, 0.1, 10); if(len(pts) < 10){ removepoint(0,@ptnum); } So if there are less 10 points find in 0.1 meter area, blast the particles. Then you can mesh the remaining. Hope this would help.

  35. Only mesh flip particles that are closest together?

    DonRomano replied to JFWfilms's topic in Effects

    Hey, in the flip solver you have a droplet attribute. Igor mentions it in the notes at the bottom right, you can use it to detect droplets, and just before your mesh you cleanup all those droplets particles and mesh only the ones that are not particles ! Cheers,

  36. Use Ordered Menu to Change Parameters in Tool

    grafikzeug replied to grafikzeug's topic in Tools (HDA's etc.)

    Here's what I've tried. Not very successful ... DropdownToChangeValues.hipnc
  37. grafikzeug started following Use Ordered Menu to Change Parameters in Tool
  38. Hey folks, I have a simple subnet that I use to reduce the poly-count of incoming geometry. I have exposed some parameters and added the ordered menu "Level of Detail". I want to be able to use this dropdown menu as a list of presets to fill in the three values into the fields below. I then want to be able to adjust the values via the sliders. I'm sure there is a straightforward solution to this that I do not see. Thanks a bunch for your help, Felix

  39. Out of sync collision mesh and fluid

    art3mis replied to art3mis's topic in Effects

    Attached fileUpload.hiplc
  40. @Atom Thanks It seems to happen far more often than 24 frames visually. What I had in mind was that the connections basically start connected, but I want some of them to occasionally disconnect if they become too short or too long or reconnect if some come back to 'normal length' again. And then that connection would go disconnect in an eased (keyframed?) way toward the middle. And I want to check if that is needed every 10 seconds or so. If I change your %24 too longer it no longer works. I don't quite understand. Here is the result of my failed trying so far, haha.. my head hurts: CheckEvery10SecondsAndConnectOrDisconnect-elaborated2-failedTrying.hipnc and a psuedocode was written before I went and pre-implemented those CHOPs: [image] edit: Never mind guys. I think I want to go too fast... I need to break this up into smaller problems.. edit: I think first the @primnum of the created connections need to become stable and not change all the time in order for me to work on them.. somehow. If anyone has an idea, it’s still welcome.

    Hi thanks for the reply! Sorry but how would I go about checking the proximity of each point?

  43. Out of sync collision mesh and fluid

    art3mis replied to art3mis's topic in Effects

    Here's just the first 120 frames with the premesh particles and actual collision vdb. I reduced the Collision Velocity Scale to 1 from 1.5 which seems to help a bit but still an issue. I am wondering if its another setting in my FLIP solver I need to play with? collision_sync_v2.mp4
