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" - Today

exact measures of a primitive (?meters by ? meters)
anicg replied to anicg's topic in General Houdini Questions
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. -
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? -
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

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

trigger a keyframed animation or chop clip from Vex ?
Librarian replied to flcc's topic in Scripting
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 -
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

FLIP> Substeps on Solver or DOPNetwork?

Thanks Tomas. -
Hi there, Have you try fuse sop? Also are those two individual geometry?

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. -
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?- 3 replies

FLIP> Substeps on Solver or DOPNetwork?
anim replied to art3mis's topic in General Houdini Questions
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 - Yesterday

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

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.

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, -

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

Check value every 10 seconds and trigger animation based on value
Krion replied to Krion's topic in Scripting
@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. -
Could you upload your scene file?

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

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
