Go, take a look. Come, say Hi. It's nice there 😊

Houdini 20.5 Sneak Peek - check out some of the upcoming new tools and enhancements that will be in the next public version of Houdini! More information to be revealed at the Paris launch on June 18, 2024.

@yannikwenk What happened to posting less and less, reading less and less, letting the platform slowly die, like we did with Facebook? 😅

@danialghods_ Do it!

was just reminded that I wanted to release an octane shading tutorial - but that´s been so long ago that I feel a certain sense of shame to do it now 😅

AAAH! i am going freelance! for the moment you can reach me at denis.j@outlook.de see y'all around! #houdini #freelance #3d #3dart #redshift #Octane

youtu.be/posFPzXqWdg Manu & Mo are back, exhausted and excited. Now you can get a master's degree with them! (Applications open May 2nd - design-digital-futures.de)

@danialghods_ @tokyomegaplex I can really recommend reading through the great Karma Pyro Shader docs. Things like the multiscatter extinction falloff can greatly reduce the bounces needed for good results. sidefx.com/docs/houdini/n…

@tokyomegaplex Oh - my bad yeah, Karma is slow. I somehow still directly associate Solaris with Karma. My main gripe with Octane volumes is that I can't make them look good lol.

So, how many of y‘all actually use Solaris? Why, why not?

@zachlieberman This demo is built around a plugin for Houdini FX, however I'm pretty sure you could built the same thing in something like Comfy UI or just using the Diffusers python module.

@zachlieberman For diffusion models, exploring the embedding space of a prompt can result in lots of weird and wonderfull outputs. We did a couple of experiments with this last year: youtube.com/watch?v=p3oVCc…

I have to give a short lecture / demonstration about generative ai coming up. what are your favorite "demos" or workshop activities ? specifically things that go beyond prompting and show how you can connect tools together? or show more what's happening "under the hood" ?

original idea is based on a concept called dubins path, a method to connect points using the shortest curves an object would need to travel. mix that math with houdini's extrusions/vdb tools and you get some interesting looking furniture

@edbrown3d You can find some models on huggingface that are trained exclusively on CC0 or Public Domain images (mitsua-diffusion, for example). Obviously they won't perform as good as models trained on the whole internet, but I think @ugstuho had good success finetuning them with his works.

There has to be an ethical, open-source alternative to LAION, and Stable Diffusion and Midjourney have to establish meta-tagging or royalty payments if they’re gonna allow named artists as prompts I can’t believe trad artists are getting fucked worse than musicians here

@3Dmattias @FreyaHolmer @entagma Yup, Mo did a little series of them in our advanced setups course on Patreon. I can also highly recommend everything about the poisson equation from Matt Ferraro. With bonus cat caustics in his blog post! mattferraro.dev/posts/caustics…

@FreyaHolmer Poisson solvers are almost magical. So much can be done with that tool. I think @entagma did a really nice series of tutorials on them a while back for houdini.

brb just gonna paint a normal map real quick

In case you're looking for the scientific term of "those Aphex Twin logo curves":

@christophertape @CellCellPress Our friends at @entagma (themselves big fans of turning scientific papers into 3D artwork) were kind enough to host this step-by-step tutorial where we show you how to use @sidefx Houdini to generate data-driven Waddington landscapes. entagma.com/houdini-tutori…

🚨New @CellCellPress cover! We’ve been working with the great @christophertape again, visualising the Tape lab’s single cell colorectal cancer signalling data in two new papers out today. But wait! There’s a lot more to this story than just the cover… 🧵

Very excited to share two papers published today in @CellCellPress describing stem cell plasticity in CRC. (1/22) cell.com/cell/fulltext/… cell.com/cell/fulltext/…

@PaulEsteves28 I'm going to hate me for this but: Just wrangles! No transform sops, no sweeps, no subdivides, nothing but wrangles. Solvers or For Loops only when absolutely necessery. Let's see how many I can do....

@chriskopic Uh oh, I summoned the vex beast!!

youtube.com/watch?v=uxevpt… #vexember is coming!! What better way to ramp up to Christmas than days filled with joyous VEX!!!!

@planetzomax @danialghods_ FDM is easier. There's a risk of burning yourself from the hot nozzle, but that's generally about it. There may be a risk of plastic particulates while printing (one study 8 years ago suggested that) but this is still debatable. I'm fine with having one in my living room 🤷‍♂️

@planetzomax @danialghods_ In terms of safety: For a resin printer you really want a cellar or garage to put the printer in. Resin is nasty stuff that I wouldn't want anywhere near my living space. FDM printing is easier.

What excites you right now?

@planetzomax @danialghods_ I had good results from the ideenbaeckerei. But that was over a year ago, don't know their quality now. But your typical resin model was around 5-10€, so easy on your wallet!

@chriskopic @danialghods_ What is your go to print service? I remember shapeways but that was always rather expensive.
