Paul thank you a ton for this tip. I watched this video months ago, and thought "this is mind blowing" but never decided to actually use it till now. I tried it to drive Houdini vanilla nodes, like the scatter sop, or a transform sop and it worked great like in your video. But when I tried to drive parameters of an custom HDA it didn't work. I tried with a few HDAs that I created, but none seems to be working. I'm wondering what am doing wrong. Is this supposed to work on any parameter of any node regardless ? EDIT : This seems to works only with compilable nodes (I guess the compilable nodes are also the ones with a verb counter part correct ?). Also according to my 10 minutes experimentation, the option "add parameter override" in the gear menu, shows after your create a spare parameter only if the node is compilable. Now I understand the comments below about the verbs. Still super useful tip. Thank you !

installiing dependencies doesnt work :( someone has the solution ?

Thanks for this, that worked really nicely for me. I mostly come from a C/C++ and C# background so Python modules and environments can easily drive me to madness, lol. I'm glad that went so smoothly and worked as expected and you're one of the best of the best! Now, if only I could get MLOPs resuscitated ... since 20.5 I've never been able to enjoy those awesome tools again. 😢

damn does not work after installing git. shit....

Paul you are a Killer Phyton :D

I was writing the ‘detail()’ expression like a caveman. Until now 😁 Thanks

Great Tip! Thank you <3

Where did you write those codes?

What a find. how where we supposed to know! haha. Such specific steps.

the attribute from parm node is also really great for getting all your hda parameters into an internal node without having to write out a reference to each parm in a wrangle. just use ../ in the Node Path and then you can run through the dict in a wrangle and distribute the attributes to points, prims or vertices. wonderful for multiparms. if the dict stays on the nodes down the chain you can access them at any point in your node tree. your graph will also stay very compile block friendly.

Nice overview of this hidden gem ! Just wanted to add a small tip : After adding the Spare Input parm from Gear Menu, you can open the Gear Menu again and you will find a new "Add Parameter Override" entry under "Add Spare Input", this creates the "spare_parminputindex" parameter instead of doing it manually on Parameter Interface

This is amazing! Very Very Useful

Paul, why does this exist? What motivated it?

Hi Paul, I am facing an error ( ERROR: pycocotools-2.0.8-cp311-cp311-win_amd64.whl is not a supported wheel on this platform.) while installing the dependencies. I believe it has something to do with pyhton version, I did install python 3.10.6 for stab;e diffusion earlier on my system.

Fantastic, Paul! Thank You very much!

anybody knows if there is a invoke node or workaround to LOPS ?

Thank you,!

Using this technique with sop verb will be really handy. And you already made video about sop verb too. ua-cam.com/video/8xlAPideayo/v-deo.html

Very exotic method, and I struggle to understand how could I exploit it but something is tickling. Thanks for sharing

This is awesome and thank you for sharing this! All clear, and very well explained, my question is, *how the heck* did you find this out?? :D

Hey​ @paulambrosiussen I saw you mentioned this but how would you override a subset of parameters only? Another question: How do you drive something in a locked HDA? You still have to add the spare parameters?

This is insane, amazing!

Thank you!

This is available in pre-20.5 ?

Thanks!

Wow, pure black magic, thanks a lot for the tip!

Ah great info. Thank you Paul 👏

1. Is this is a hard override only? 2. Is this in the docs by any chance? 3. Also a great way to thourouhly confuse someone else using your setup, 😅 awesome info again!!

Great video!

Thanks!

Great video, thanks!

Thank you

more smoothly run unreal engine software

plz tell me your pc or laptop configration

Really helpful. Thank you so much for that. Any chance you share your sample code file with us? That would be really huge. Typed and copied everything I could see there, but there is so much more that could help us peanut brains out. Thanks so much :).

Hey Paul, following along with this today! I'm seeing the following error when hitting "install dependencies" in Houdini - do I need to set up a 3.10 python environment for pycocotools to run here? Bit stumped on the path forward. Thanks! "ERROR: pycocotools-2.0.7-cp310-cp310-win_amd64.whl is not a supported wheel on this platform."

I can't wait to try this out. ETA?

Thank you ! btw It still work for mlops 3 :)

might be a dumb question, but how do you replace the preloaded wang tile set with custom geometry?

I have problem with MLOPs version 0.1 on 19.0 When i try to open example file in every geo in mlops solver node i have same error. " Invalid source /obj/txt2img/sd_solver1/switchif1 Error: Not enough sources specified. Unable to cook the test input.. " - But it should work properly cose it example scene! machine: windows 10 i 9 end 3080 ti

It’s for beginners please inform

i accidentally deleted MLOP's shelf. is there a way to get it back? i tried reinstalling but it didnt work. thanks

I got this error (6) Could not resolve host: bootst

great tutorial! thanks a lot

Hi Paul, Thank you so much for your video. However, I have a problem with some tools. Could you please help me about it ? Btw, I couldnt find your Discord Channel to communicate.

very cool. did you ever shared your text file with all the code you copy/paste?

What are the system requirements?
