Just my luck ffs finally have a week of free time to try to learn something and it's gone.Not saying I'm lost without it but it would help.
>>967162What's your current project, OP, or what are you planning on working on?
this is the houdini general. you've made it, op. congratulations.
The thing about Houdini is that it takes a PHD in computer graphics to even get a couple of seconds of usable output out of it as well as buying in to the ecosystem of zbrush, maya, mari, and nuke and then buying expensive motion capture suits.
>>967171That's nonsense, you're just establishing yourself as a retard if you say shit like that.
>>967172no, it's true. I'm not talking your bottom of the barrell drag and drop pyro sim, im talking about actual good FX
>>967165nothing, I'm still looking for a good intro course with no success so far. Although I have only done Houdini isn't scary so I can't say I was trying much.I found Rebelway's VEX course so I'm going to do that and hope the basic stuff will stick along the way.But if you can refer me to some source where I can learn what excatly is VOP, DOP, SOP, shop, WHATEVEROP, I'll be very happy.
>>967175>But if you can refer me to some source where I can learn what excatly is VOP, DOP, SOP, shop, WHATEVEROP, I'll be very happy.ngmigive up now
>>967175>doesn't understand contexts>going through rebelway's vex courselollmao even
>>967177>>967178you may laugh but I'm gonna make it... mainly because it's just a hobby.on another note it seems you had a proper introduction with the software so tell me where can I get to read or something about this stuff
>>967179ironically, its not even worth replying to you
Anyone using the Houdini 20 cracked version? Had your data stolen or PC bricked yet?
>>967194stop invading a good houdini thread with your poor skid row talk. You are never ever going to make it
>>967162With AI wouldn't it be better to learn Nuke?Image and asset generation will still have to be composited!!
>>967177>>967195Post your work
>>967175the documentation, faggot.
>>967245>documentationOh look a faggot on a small pony calling people faggots. Your advice is like telling people to read a dictionary when they want to learn a language. But if you learned it that way congrats you must be the biggest autist in the room wherever you go.
>>967251Is this for real?
>>967175If you are unable to find for yourself what different operator abbreviations for Houdini are, then you are mentally retarded simpleton, descended from family with long history of mental retardation. Fucking imbecile
>>967256Anon it's not that deep
>>967251>>>967254probably not, and yet I still used less words than he did. trolling skill issue.
>>967258I'm starting to realize that Houdini isn't scary is a really shitty first experiance with the software.
>>967263you need a PHD in computer graphics to get anything out of houdini. I'm Not shitting you.
>>967265it's true, that's why you should pay me 250k base salary just for opening houdini.
>>967265I'm studying computer science at a university right now so vex is quite intriguing for me it's coding with the added reward of visualization so I'm not complaining.
>>967171Indeed on the 'phd' part, I've started learning vector math on the side. Lucky I have a quick mind
Why is there nobody I can just pay an hourly rate to tutor me in this shit over zoom? I've done and understood all of the getting started tutorial shit and now I have so many specific questions on how to accomplish effects I'm going for and I just need someone to help me connect the dots
>>967331Ask away
>>967331>Why is there nobody I can just pay an hourly rate to tutor meyou can. just make a post in thinkprocedural discord. don't be surprised if you can't afford it though.
>>967175You know that VEX is not as hard as people made it out to be. I'm still far away from being an intermediate as few people pointed out because I was too retarded to read the documentation, but I don't think it was the worst pick for the second course I've ever seen for houdini.
>>967331pay a few shekels for cgwiki patreon or paypal, you'll get access to discord where all the heavyweights of vex are hanging outpost the link here once you're in pleaseor sign up for proceduralkate's patreon and you'll get once weekly private mentorship over zoomshe's so cute so I can't sign up because I would creep on her and never get a job in the industry ever againhttps://houdini-course.com/mentoring100$ for 60 minutesgood deal, very knowledgable, seems like a good dude
>>967565>100$ for 60 minutesjesus fucking christ
i'm gonna write some stuff down about solaris and karma in h20 and would appreciate it if someone could point out if i'm wrong about something:ACES:>to use aces in karma (and solaris in general) just use the new ocio settings panel, rendering space:aces cg, view transform: aces srgb 1.0>^ need a restart for this to take effect>color space rules below handle texture conversion>mtlximage node has file color space dropdown but it doesn't seem to override this rule (?)>karma ocio color transform node does seem to work in karma xpu (some youtube video suggested it didn't)lights:>they added spread to lights - still not in the usd spec, but available in the karma tab for lights as an override>karma light filters now work in xpu>karma gobo light filter does not play well with the spread light parameter - if you want a pin sharp gobo, disable spread and make the light tiny>no way to color correct hdri images on the node or in the light shadersubdiv:>rendertime subdivision is combination of two nodes>meshedit > subdivision scheme to set type>karma settings / render geometry settings to set dicing quality to set subdiv quality
>>967565I've started transitioning our team from Maya to Houdini and after looking around to see what resources there were I chose houdini-course to help get our artists up to speed. I don't know about the mentoring, but the structured courses are very very good. He's got a bunch of free videos sprinkled in there so people can check it out. Bonus: he has a normal, tolerable voice. Found that to be pretty important for me personally.Good advice about getting into the cgwiki discord. The thinkprocedural discord is retardville by comparison.>>967577Not 100% sure but sounds pretty accurate overall.>mtlximage node has file color space dropdown but it doesn't seem to override this rule (?)The colorspace stuff isn't implemented yet on the MaterialX spec side of things from what I remember.
is there really no way to drop a karma material builder with python? it's a preconfigured subnet with a bunch of inherited properties and it's a complete pain to recreate (also, why the fuck should i have to?)there has to be a way to just execute the menu item with python right?
>>967565>>967582Thank you that's actually super helpful. I signed up for proceduralkate mentoring and will post updates on how it's going if anyone's interested. Just bookmarking houdini course for now since I'm absurdly poor and would have to be really strategic about what I'd shell out 100$ for
>>967781Please do post your work when you make something in Houdini, anon
>>967699i have a working solution for thisno i will not be posting it out of spite...maybe i will, later. somewhere else.also wrote a nice script for quickly soloing/previewing individual nodeskarma is fantastic
>>967812>karma is fantasticCan you tell me about this, senpai?>what are the limitations of H20 Karma XPU uniform volume?
>>967814i have no idea, anon i haven't played with it yet.the fog box is fully supported in xpu now though right?
>>967815yes
>mfw materialx compositing node options are actually pretty good>mfw retarded so like the convenience of a single uber node where i can cycle through different blend modes easilysigh, here we go again
How is APEX rigging, people?
Why is there no cone node? Why do I need a PhD to make a pyramid with a square base? Why does chatgpt make up nonexistent ways of creating this pyramid instead of just saying it doesn't know? Why is documentation required to make a pyramid with 4 sides and why does said documentation not exist? WHY IS THERE NO CONE NODE

just spent the last 2 hours trying to figure out how portal lights work in karma/solaris. i've figured it out, but i don't know if i should feel retarded or i should be angry.what i thought was the way:1. create dome light2. create rect light3. add render geometry settings to rect light and enable 'is portal'4. optionally add rect light 'portals' parm in dome light5. optionally add dome light to 'portal dome lights' parm in render geo settingsi spent way too long a/b'ing renders trying to see if any setting changed anything. nope.turns out CANNOT use a light as portal lightportal lights must be regular old geometry primsyes. you just make a plane and use render geo settings to mark it as a portal it just werks.
>>969125>solarisjust use katana
Anybody know if you can do looping fluid sims? I want to create a simple looping waterfall like pic rel
>>969993Same principle as looping video. Copy the cache, offset in time, "crossfade" the particles by using a threshold that hides or reveals particles as a function of time.
>>969993Ignore >>970015 anonJust simulate FOREVER
so are we eating good or what?everyone happy with houdini 20?
OH MY GOD THE KARMA HAIR SHADER IS SO MUCH BETTER THAN BOTH THE REDSHIFT ONES PUT TOGETHER HOLY SHIT FUCK MAXON AND THEIR INCOMPETENT GARBAGE KARMA DOMINATION
Intro to Karma Materials for Beginners in Houdinihttps://www.youtube.com/watch?v=IhkHl2Bpoc4
who here tried Stable Houdini and/or MLOPS?
>>968869>>968866>>968818>>968871The most straight forward way to make a pyramid or cone shape in Houdini is just to place down a attributewrangle write a few lines of expression code like this.int sides = chi("num_sides");float height = chf("height");float radius = chf("radius");matrix trans = ident();vector pos = set(radius,0,radius);int pts[];rotate(trans,(PI*2/sides),{0,1,0});int bottom = addprim(0,"poly");int top = addpoint(0,set(0,height,0));for(int i = 0; i < sides; i++){ int pt = addpoint(0,pos); pos *= trans; append(pts,pt); }for(int j = 0; j < len(pts); j++){ int side = addprim(0,"poly"); addvertex(0,side,pts[j]); addvertex(0,side,top); addvertex(0,side,pts[(j+1)%len(pts)]); addvertex(0,bottom,pts[j]); }>It's literally that simple.
>>976014Houdini failed to adapt to AI over the past couple of years and is stuck firmly in the past with this type of stuff. It's only a matter of time now before they file for Canadian bankruptcy
>>976017Isn't Houdini like the only 3D package that is adapting to AI? They added some features for support of AI models.
>>976036no, they didn't add anything, look at the H20 release notes
>>976039Yes, they added MLOPS
>>976042mlops is not what anyone means by adding ai to the program
>>976044Ok, so now you push the goalpost.MLOPS literally stands for machine learning operators. Which supports AI models.
>>976045machine learning is not the same as ai. You should know that.People want something that can compete with sora and sora 2/3/4 etc (it wont)
>>976046You just exposed yourself as a retard.
>>976048huh?
>>976046They're both useless scams, Cris.
>>976055I'm not him. I've been to art school, been trained by an academy award winner, have gotten professional work, and dont live in venezuela.Ai is not a scam.
>>976046MLOPS support AI models and all of modern AI breakthroughs are in machine learning.You are trying to argue semantics because you know you are wrong. I wouldn't have called you retarded if you weren't so confident while having absolutely no clue about anything.
>>976065>You are trying to argue semantics because you know you are wrong.>Can there be AI without ML?>Historically, AI preceded ML. When researchers first created AI, they didn't even have ML in their minds. An example for the use of AI without ML are rule-based systems like chatbots.

just doing a full dress vellum sim on a walking character and by default the velocity coming from the translation is pretty out of control.had to do extract the transform and move the character to the origin for a psuedo walk-in-place to get a decent result.is this standard practise?
