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
@@obeidazakzak Great tip! Personally I’ve never found the Add Parameter Override option. It doesn’t show up for me even if I have a spare input made already, but I’ve seen it for others
Well it was there on the screen record at 4:29 ahah
@@obeidazakzak lol
@@paulambrosiussen I took a look at the ParmGearMenu.xml file and it seems that this option appears only on Sops having a verb (and wich don't already have that specific parm). So basically all HDAs and subnets will not show this option, as they don't have verbs. However, this made me discover that parameter override by dict attribute is only valid for Sop verbs, and does not work on spare parameters (only parameters being part of that sop verb).
This is amazing! Very Very Useful
I have always asked what this imaginary line means, thanks for sharing. Do you know if it is possible to link other parameter attributes this way, such as Disable, Lock and so on?
Paul, why does this exist? What motivated it?
@@erichocean8746 my guess is it’s a mechanism that got built for the sop verb execution using invoke graph. I have a video on that on my channel!
that was my guess too. i remembered that that, (dict detail attribute) is exactly what the apex invoke graph node expects. i also remember how terrible using the attribute adjust dict node is cause it won't let you do nested dictionaries or arrays. the next best option is to build up the dict in a wrangle, which is still pretty tedious.
Paul, could you link that video? i was able to find your sop verb video on invoking a compile block, but did you also do a video on using the apex invoke graph node? i know i saw something on youtube about using that node to get parms into an apex graph, but i'm not sure it was your channel.
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
i’m struggling to come up with a use case with this + sop verbs, could you share what you had in mind? thank you :)
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
I don't remember honestly, but today I needed to use it and figured why not share the knowledge :)
@@paulambrosiussen well, regardless how you did it, this is gold. :) thanks for sharing.
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?
@@gt_kenny To override a subset you can do what I showed in the video where I created a dictionary attribute called “parms” in a wrangle, where I only added a single entry. For the locked HDA, yes you would need to implement this before locking it. But it helps where you for example need to dynamically drive a ramp or multiparm.
This is insane, amazing!
Thank you!
This is available in pre-20.5 ?
@@desocrate yes works in older versions too. No need for 20.5. That was just the version I recorded my video in
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!!
1. What do you mean by hard override? You can override just a subset of parameters if you want. 2. Not that I know of. I have never found it listed anywhere, but would be happy to know as well. 3. 100% agreed lol. Super powerful feature, but Discoverability & UX is lacking
@@paulambrosiussen Cheers! by hard override I mean it totally overrides the parm with the value, no adding/mult/divide options to compose values.
@@johanboekhoven No. Replacement only
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, thanks! Check out the other videos I uploaded. It links to some written materials!
@@paulambrosiussen oh great, thank you very 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."
Hey could you join the discord? Much easier to troubleshoot than here!
@paulambrosiussen7709 Of course! I'll make a post there
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?
Hey, you can just create your own geometry with the same attribute values!
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
Beginners in what? Python or Houdini? I have seen both be able to follow along. I would say the minimum requirement is a fundamentals understanding of Python.
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?
Started using `Reference Copy` for template mesh when re-topologizing, `Invoke` functionality should come in handy too. Thank you!
Super useful, thanks 🙌
This is Python Gold Paul :)
this doesnt work. i have followed this tutorial over and over and no luck
Hey guys, I have already a folder with tons of models and Loras, I share it between a1111 and comfyUI, I just need to change the yaml file to point it to the directory. But I'm not sure how to edit it to work with Houdini. For instance I have this path "A:\a1111\stable-diffusion-webui\models\Stable-diffusion\v1-5-pruned-emaonly.safetensors" but it's giving me an error, Error Invalid source /obj/geo1/sd_tokenizer1/tokenizer Error: Error generated by Python node. The specified model does not exist locally. Because the 'Local Cache' checkbox for this node is enabled, it also wont be downloaded automatically. Specify a valid local model or disable the 'Local Cache' parameter. a I want to be able to use the folders that I have already with models, loras and controlNet, Is this possible? { "MLOPS_MODELS": "A:/a1111/stable-diffusion-webui/models/Stable-diffusion" }, { "MLOPS_SD_MODEL": "A:/a1111/stable-diffusion-webui/models/Stable-diffusion/v1-5-pruned-emaonly.safetensors" },
How to I uninstall the old one?
Amazing work! can you share the python files or make a longer masterclass about it? :)
but how to convert safetensors to ckpt?
