Hello
I have been working on a massive OpenWorld HDA for my team, which will assemble many other bricks, with organic logic behavior and rules driven by the artist.
Some of my multiparm have 3 levels of recursion with dozens of setting each.
- Have you been using method like Cacheif to only recompute the needed loop elements or other methods?
- I guess most of you will have choose PDG to handle the check that , straight out of the box right?
Will you convert the multiparm to a Dictionnary with Python, then to some global var to different HDA processors?
Hope it makes sense, happy new year!

Considering im building with python to texture a Heighfield , how will you sample in COP the result of the texture layering of my x diffuse map injected with the material builder? As houdini apparently can't handle more than 10, each time i have more than 9 differents texture materiax index , i have to create another pile of 9 and build the mask alpha to blend...
How could i bake the all thing?

yes, why was this removed from the new filecache and not even present even the labextended cache?
It was indeed of the most usefull feature.

That is really good unexpected news.. I mean everyone has been asked for COP improvement for years, but that update has not been claimed and i like it better than a cloud generator !
Sidefx has always put some kind of party cone bags in every of this release, it will take us sometime to discover all, thanks Sidefx!
PS: i usually disable thumbnail generation in COP, faster and more stable

Im using a volume wrangle to computer curvature for my heightfield and like the Sidefx node, im getting
Both solution are uncorrect, so my question, is it possible to solve the equation for compute curvature for a 2d volume?
First pic is sidefx method, second mine, third and last are custom but i have to get out volume2d to compute...
Cheers!

I have probably missed something with svddecomp , everytime i struggle with one direction which looks off to me..
So if i take your version, i get the reduction red plane, doesn't look that correct not?
I could improve the result with some "prefiltering", which give me the blue plane , way better already...
Have you also noticed or is it me only?

WASD is okay for me, but Is it only me but how to properly rotate with the enable mouselook up? as soon as i active this, i feel like being captured in a space highspeed space-gravity test machine , are you guys being able to gain control ? This is an old post, is it still supposedly to work?
That would be a good tool The Labs with a "walking" mode

Most of responsability is driving the procedural design Rnd for my actual client, i didn't grew up with a python around my head , but for python panel, there are some good starting template you could look around
Some could be the the sidefx USD assetgallery.py
located here or some misc repo
But it is still not a solution i will like to go in most case, i will rather like Sidefx to extend the current possibility we have right now

Yes, for my question, my friend more into pipeline than the departement i m leading , WaffleboyTom pointed me to pypanel and the example done by excellent egMatLib

Is there at least some Python hack that could without dealing deeply into the HDK allow me to display some thumbnails pictures of my menu list? And eventually to have a special window being open with all items to scroll and select one?
Do my words and need make sense? Have you done it?
I guess many of us will be happy to be able to build some better tool with this kind of possibility more directly linked to houdini current HDA dev and will make Houdini even more artistic friendly ...

To make more easy to extend the HDA tool's interface possibility?
Python state it arrived late in Houdini, but it's great progress now how could you get we are still far away from what is it possible to do Blender's in a relatively acceptable time.
For example, how could you have your HDA interface popup near the mouse arrow? or how to have a popup window with an asset library?
I might have miss something, but i feel frustrated to give my artists tools that don't have all the smooth ergonomy i would expect in 2023. Some new developpement to extend HDA tool interface will be welcomed, and hopefully without an overcomplicated way

Karma renders VDBs using nanoVDB from nvidia, cycles does not have that (yet?).
Apparently, NanoVDB has been a part of Blender Cycles since 2021, at least according to Nvidia, so why does it take so long to render volumes in Blender compared to Houdini XPU?
Interactive volumes with NanoVDB in Blender Cycles [www.nvidia.com]
Different, but a solution which is gaining popularity is GPU fluid Embergen. https://jangafx.com/software/embergen/ [jangafx.com]
We have Axiom In Houdini , but i can't seen much things done with it
No doubt we are switch to more GPU solution, If some heavy simulation may still be out of reach today GPU RAM, once you put your hand on the interactive speed , hard to come back!

So after 20 years of wait, materialX and USD is step forward but we are still dependant on the GPU hardware, there is no universal open CL code which could satisfy multiple GPU alternatives?
It's a pity for an engine which has been started "recently" we can not have something already GPU hardware agnostic.

It was more a joke, slow down , i have no clue on that
but yeah some of my old colleague, top people at Weta, Pixar,etc Autodesk, did all left almost in the same time and now works for Nvidia.
They do has an increasing monopole. While im quite in admiration for their achievement, this is also a very serious concern and potential dangerous fact
Silence is not necessarily a reason to panic , it's a long run fight...

I think the Delay is due to AI and integrating it into the core program. They probably floated the h20 stuff just to let you know it is coming at some point. Houdini has a large learning curve. If AI can drop that curve it would make sense to integrate it.
I would like to believe this, but i really doubt it's the case.
How to plan to use "AI and integrating it into the core program"? Are you not taking some serious shortcut here?
There will be a shift of paradigm at some point for many tasks we are doing now, but let's be serious it will be for tomorrow 2023.
I expect much more than a feather tool, SSS and crypto support in karma. Sidefx is not Epic or Unity with a staff of thousands, i obviously understand some priority should be taken and we have to be patient. But to a certain point. If they can't show they could keep the same pace as before and follow the rise of competitors, well that's certainly going to question my faith in my favorite tool.
Did Nvidia offer a golden bridge to steal Sidefx's best staff like they did in many other place?

Well, many people here did complain about houdini lack of modeling features and it's my right to express myself on the subject and not agree with what others consider as priority.
What does your point here bring constructively? Why is your experience and opinion so much more valuable than mine?
If Sidefx is so visionary and doesn't need such "basic advice", why are they late on achieving what over software already have reached today?
I have already posted other specific feature and feedback before. Some of my bestprogress came from what some most people would called basic things and maybe it's also what houdini missed today. Do you think i need for example a transform by center or just a full node but which could be resume by 2 lines of codes. I do not, but i could see tons of this. While when i enter a Houdini node, nothings is named, nothing is commented, or ordered... This , is what i would called a basic thing for a professional.. What do you have to say here?
Why do we have a menu entry for , attribute noise, attribute noise float, attr noice vector. Same for point wrangle, prim wrangle, vextex wrangle, while one is enought to encompass all of them and not spam my menu for nothing really pertinent. For me as well this is obviously some other basic things which i don't think it's a good idea but i imagine some others are thinking differently and possibly find this convenient and important for then. (?)
After why is it basic? I have met many people in my carrier who have these impressive pretentious talk and building complex code but poorly perform at the end , just because they lost track or have no aerial understanding of the all process.
With my respect, you *look* like one of then

Urgency
Some urgency for me is not into making Houdini a modeler like Zbrush or blender, battle is already lost. But concentrate on his strength. A *BIG* weakness for myself is how much, long complex and wacky to build user interface for tools. It's pretty much the same weakness like for realtime viewport feedback where houdini looks really outdated compared to sexy blender Eeve which day after day is gaining charming more and more people.
Sidefx needs to recognize this and react quickly is they don't want to lose a large part of their market...
Houdini is still my favorite software i tried in 30 years, but you have also to convince my clients in a world where things move very fast and you have no choice to be fast and sharp too.
There are special points i will really like to emphasize because im worried if you miss this next move, @chrism

Lots of good feedback here but just a reminder to log RFE's and BUGs for the issues you care about so that they go into a bug database, get tracked, and assigned to programmers.

Thanks you for your answer! It makes sence even if I was hoping for a more easier straight forward solution
We agree here it's one of those thing which should to something smoother isn'it?
Or maybe if vulkan come and it's ready to match Blender eeve render feedback, i could bypass LOP incase i don't need to build a USD scene
